FW: CSETI Announcement - Urgent Disclosure Project Update
Please read and forward. -Original Message- From: James [mailto:[EMAIL PROTECTED]] Sent: 14 February 2001 21:39 To: Young, Stuart; Raf; Nicky Gosney; Nick; [EMAIL PROTECTED]; John Boddy; Iain; Green, Karen; Darren S; Andy; [EMAIL PROTECTED] Subject: FW: CSETI Announcement - Urgent Disclosure Project Update -Original Message- From: Tony Craddock [mailto:[EMAIL PROTECTED]] Sent: 14 February 2001 05:35 To: [EMAIL PROTECTED] Subject: CSETI Announcement - Urgent Disclosure Project Update Please Post and Distribute As Desired Since August of 2000, the CSETI Disclosure Project has recorded the testimony of over 100 military, government and related witnesses to UFO events and projects from around the world. The testimony of these courageous witnesses creates a permanent archive with the most profound implications as it constitutes dozens of first-hand, often top-secret witnesses to UFO events, internal UFO -related government projects and covert government activities related to UFOs, Extraterrestrial Intelligence and exotic energy and propulsion system projects. These 100 witnesses constitute the tip of a larger pool of over 400 prospective witnesses, many of whom would prefer coming forward first in formal Congressional hearings --which we hope will follow the upcoming planned disclosure event. This testimony is on broadcast quality digital videotape and audio tape. Printed transcriptions of the testimony are currently being created. We are requesting that any further military, government, government- contractor or related witnesses to UFO events and projects contact CSETI Director Dr. Steven Greer immediately for inclusion in the briefing materials and the upcoming disclosure event. Such witnesses may contact Dr. Greer via the CSETI website at www.cseti.org http://www.cseti.org/ or at 540 456 8302 (government witnesses only should use this number, please). Additionally, any other substantial, supporting evidence, such as government documents, high quality UFO photographs and videotaped images, hard evidence etc. should similarly be referred to the project for inclusion in the final briefing materials and disclosure Press Conference. The date for the Disclosure Press Conference and related activities in Washington DC has been set and will occur in the Spring of this year (2001). Prior to the Disclosure Press Conference we will be conducting private briefings for key leaders in society, government and related institutions (for example, members of the US Congress, White House staff, scientific and religious leaders etc). If you have good access to such leaders and can assist with arranging a briefing please contact Dr. Greer as soon as possible. This body of testimony is being edited and the over 100 hours of testimony will be condensed into a 2 hour briefing video. Additionally, a written briefing document consisting of witness testimony transcripts, government documents and important case material and policy papers is being prepared for use in the briefings and in the Disclosure Press Conference in Washington. The Disclosure Press Conference will present many of the government witnesses in person, and the other evidence and briefing materials will be available to the media at that time. People with excellent national and international media contacts who can assist pro bono with media coordination are invited to contact Dr. Greer also. Unfortunately, a documentary containing this witness testimony will not be available as there are insufficient funds to complete such a project. We would like to thank all of the supporters and contributors to this historic effort and especially the witnesses who have come together to let the world know the truth about this very important matter. Anyone who would like to help support this effort is invited to make a tax-deductible contribution to : The Disclosure Project, PO Box 265, Crozet Va 22932. Further updates will be issued as the date for the event approaches. Again, we would like to thank our many supporters for their assistance in and dedication to disclosing the truth.

Order of the update log
Are entries in the update log recorded in the *exact* order that the SQL 'hits the database'? I am using mysql version 3.22.22. I would normally assume the log was accurate but someone just told me that with mySQL log entries can be out of order by a few seconds because different mySQL processes write to the one log file. Thus they have to wait for the other to complete. Is this true? Also, are log entries written in the order that the SQL requests come in, or in the order that the requests are completed?

Win2K and MyODBC?
Hi, When I ran the application that uses myodbc as the interface to the mysql server (linux) on a Win98 platform, it works fine. But when I transferred the application to a Win2K pc and run it, I cannot even get through a connect. I have already granted access for the Win2K pc to access the mysql server with the correct username and password. I tested it using the mysql gui and it connects fine. Are there any known problems when using myODBC with Win2K? Or are there any write ups on what needs to be done to get myodbc to work in Win2K environment? Thanks, Li Sze

Re: Help please: getting the total from the results of SUM
hi rus, It seems my first question was not very clear. I wanted to use a function that I don't know if it exists or if there is some way to do this. Its name is TOTAL and what it does is add all values ignoring the GROUP BY clause, unlike SUM that is affected by GROUP BY. So from a bigger table than what I had below: Event_Num, Name, Amount 1 Name1 15 2 Name2 15 3 Name3 30 4 Name1 45 5 Name2 20 6 Name3 35 I can get the following output: Name, Amount, Total, Percent Name1 60 16037.5 Name2 35 16021.875 Name3 65 16040.625 So if the function TOTAL exists, I can do this: SELECT Name, sum(Amount) as Amount, TOTAL(Amount) as Total, 100 * Amount/Total as Percent from table1 where ... GROUP BY Name; and TOTAL would give me the TOTAL of all Amounts so I can use it to calculate for percent. I want can do this calculation in one line. :) Currently I use two SELECT statements, the first to get the total, then use that value to calculate for the percent. jerome From: "Rus" [EMAIL PROTECTED] To: "jerome auza" [EMAIL PROTECTED], [EMAIL PROTECTED] Subject: Re: Help please: getting the total from the results of SUM Date: Thu, 15 Feb 2001 00:47:49 +0300 Did you try select count(*), sum(amount) from table1; you also can use ... count(if(field=value,1,NULL)) ... - Original Message - From: jerome auza [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, February 14, 2001 2:49 AM Subject: Help please: getting the total from the results of SUM Hi, Is it possible to get the total from the results of SUM in the same SQL statement?

RE: Can't connect in Windows 2000
Hi James, Yes this IS mysql related as MySQL does not support a Telnet connection to it :) You can either use the mysql.exe utility in the mysql\bin directory to use your mysql server or try one of the many MySQL GUI clients available in the Contrib section of www.mysql.com ,for ex. http://www.scibit.com/Mascon which will get you started fast.

Try to connect to your server with the mysql client and type: show processlist; This will show you what query it is working on. Maybe you need to start the mysql client with the -A option to prevent it from reading table info (which might wait for the query that mysqld is working on). When the cause is still not clear to you, then post the output of the 'show processlist' to the mailing list. Maybe we can help then.

Compiling MySQL for other character sets
Hi all, Would like to ask a few questions on how to go about compiling support for a multibyte character set into MySQL. When I compile by default without specifying any character sets, it's supposed to compile in ALL character sets. Yet, when I try to run a mysql daemon that was compiled in this manner, the option "--with-character-set=gb2312" will result in an error that says they can't find the specified character set. Why is this? When I compile using the "./configure --with-charset=gb2312" does it mean that ONLY the gb2312 character set will be used? what do I do to specify that mysql is compiled with a few character sets? When I run mysqld with the "--with-character-set=gb2312", what kind of behaviour can i expect when i sort normal Latin ascii text then? I'm running 2 websites that searches a mysql engine when running a search, one English website and one Chinese GB website. When mysql is running the default ISO-8859-1 character set, the Chinese website wouldn't work correctly. When running the gb2312 character set, the Chinese website works, but I'm worried about the English one then, hence my question. If possible, I'd like to avoid having to run 2 instances of the mysql daemon, and consequentually 2 instances of the Apache daemon as well.

Re: SELECT help
Sir, haven't you posted this before? It looks familiar. You can't apply an aggregate function to an entire table if the SELECT statement has a GROUP BY clause. The aggregate function will return totals for the groups, not for the entire table. Bob Hall Can someone help me combine this statement ... SELECT d.*, b.invoice_id FROM domain_info d LEFT JOIN billing_info b ON d.domain_id=b.domain_id WHERE billing_cycle = '12' OR billing_cycle = 'Z' OR billing_cycle = 'C' GROUP BY domain_name with this statement ... SELECT sum(ammount_due) FROM billing_info WHERE domain_id = $domain_id AND status = 0 The code is for billing software to manage the accounts of my server clients. In the first statement I am selecting information about each domain from the table domain_info that are billable for this billing cycle. Also in the first statement I am checking to see if any invoice_ids exist for the domain in the table billing_info. If there are no ids, the code knows to add a setup fee to the charge. If there are ids, then they domain has already been charges in the past and been billed for the one-time setup fee. The second statment gets the entire ammount owed from the table billing_info. Anytime a domain incurs a charge (positive) or pays an invoice (neagtive), a line is added with this in the ammount_due collumn. I can't seem to get an error free result ... can anyone offer suggestions on some working codes that gets both of these statments into one? Thanks!

Re: Can anyone do this ?
Sir, 99% of the time, if someone can't create a TEMPORARY table, it means that they're using an earlier version of MySQL that doesn't support temp tables. The best thing to do is to update to the most recent version. If you can't update (e.g. if MySQL is being maintained by a web hosting service), then you will have to create a persistant table, and then delete it before ending your session. If you're going to be using the table frequently, you can leave it in your database and just empty it before or after each use. Bob Hall Hi Bob/ All, I cannot get the creation of the TEMPORARY Table to work: The select statement works fine: mysql SELECT table1_id, Count(date) as c FROM Table2, Table1 - WHERE Table2.date BETWEEN "2001-02-02" AND "2001-02-06" - AND Table2.table1_id=Table1.id - GROUP BY Table1.id HAVING c=3; +---+---+ | table1_id | c | +---+---+ | 1 | 3 | +---+---+ 1 row in set (0.02 sec) mysql CREATE TEMPORARY TABLE counts - SELECT table1_id, Count(date) as c FROM Table2, Table1 - WHERE Table2.date BETWEEN "2001-02-02" AND "2001-02-06" - AND Table2.table1_id=Table1.id - GROUP BY Table1.id HAVING c=3; If I manually create this counts table and work with that I do get the desired output: mysql CREATE TABLE count (table1_id VARCHAR(10), c VARCHAR(10)); Query OK, 0 rows affected (0.06 sec) mysql insert into count VALUES (1,3); Query OK, 1 row affected (0.01 sec) mysql select * from count; +---+--+ | table1_id | c| +---+--+ | 1 | 3| +---+--+ 1 row in set (0.00 sec) mysql SELECT Table1.*, Table2.* - FROM Table1, Table2, count - WHERE Table1.id=Table2.table1_id AND Table1.id = count.table1_id - AND Table2.date BETWEEN "2001-02-04" AND "2001-02-06"; ++---++-+---+ | id | Item | date | no_of_items | table1_id | ++---++-+---+ | 1 | Item1 | 2001-02-04 | 2 | 1 | | 1 | Item1 | 2001-02-05 | 2 | 1 | | 1 | Item1 | 2001-02-06 | 2 | 1 | ++---++-+---+ 3 rows in set (0.02 sec) Do you have any idea where I'm going wrong ? Kind Regards, -- Frank Sir, create a variable day_count with the count of days in the user-supplied range. Then set up the following temp table. CREATE TEMPORARY TABLE counts SELECT table1_id, Count(DISTINCT date_field) as cnt WHERE data_field BETWEEN min AND max GROUP BY id HAVING cnt = day_count; Now you have a table with the IDs of items that occur at least once each day in the user-supplied range. You don't need the DISTINCT if each item can only have one record per day. Now some inner joins should get the results you want. SELECT table1.*, table2.* FROM table1, table2, counts WHERE table1.id = table2.table1_id AND table1.id = counts.table1_id AND date_field BETWEEN min AND max; I haven't actually run this, which means that there's probably a mistake or three.

Re: Can anyone do this ?
Hi: the way I handle this situation is: "create temporary table if not exists tblName (somefld I need, etc.) select iptable.* (or field names) from myTable where bluemoon = yes" Works every time for me.

Kind Regards, -- Frank Sir, create a variable day_count with the count of days in the user-supplied range. Then set up the following temp table. CREATE TEMPORARY TABLE counts SELECT table1_id, Count(DISTINCT date_field) as cnt WHERE data_field BETWEEN min AND max GROUP BY id HAVING cnt = day_count; Now you have a table with the IDs of items that occur at least once each day in the user-supplied range. You don't need the DISTINCT if each item can only have one record per day. Now some inner joins should get the results you want. SELECT table1.*, table2.* FROM table1, table2, counts WHERE table1.id = table2.table1_id AND table1.id = counts.table1_id AND date_field BETWEEN min AND max; I haven't actually run this, which means that there's probably a mistake or three.

Re: Table timestamps? More specific control of SHOW TABLE STATUS command
Atle, your suggestion is for the last time a record was updated. I am interested in the entire table. The closest that I have seen thus far is: SHOW TABLE STATUS The Update_time field is most likely what I am after. However I was hoping to do something more like select Update_time from table(x) status Giving me one value back - the Update_time for table "x" of current database. Perhaps this is a candidate for function extension? Jay You might be able to use this, depending on your needs: from http://www.mysql.com/doc/D/A/DATETIME.html [snip] Automatic updating of the first TIMESTAMP column occurs under any of the following conditions: The column is not specified explicitly in an INSERT or LOAD DATA INFILE statement. The column is not specified explicitly in an UPDATE statement and some other column changes value. (Note that an UPDATE that sets a column to the value it already has will not cause the TIMESTAMP column to be updated, because if you set a column to its current value, MySQL ignores the update for efficiency.) You explicitly set the TIMESTAMP column to NULL. [/snip] .. Atle On Wed, 14 Feb 2001, Jay Lawrence wrote: Hey all, Is there a way to quickly obtain the last time a table was updated/touched?

Server configuration denies access to the data source
Within the last few days we've started having serious problems with our database. We have no problems connecting to it using "mysql" and "mysqladmin". For instance, this command lets us into the database just fine: mysql -ucustomer -p customer_database The database seems to be working correctly. However, many of our customers are having troubles getting their Java servlets and/or JSP pages to connect properly. Note that these customers have existing applications that have been working correctly for some time. They have not made any changes, nor have we. Now, all of a sudden, they are getting these errors in their error logs: Cannot load connection class 'java.sql.SQLException: Server configuration denies access to data source'. This is happening to multiple customers at the same time. The only way we can fix the problem is to shut down the mysql database server and restart it. Any idea what might be happening? We are running on RedHat 6.2 with mysql 3.22.32 from RPM. Thanks for the help!

SQL executes on command-line but not in PERL
Hi, everyone, I've recently run into a strange phenomenon. I try to tun the statement "update accounts set loggedin=10 where username='user'" -- works fine from the command line. But I used it in a PERL DBI situation and it does NOTHING -- no error, nothing. I know the PERL code is fine, because I've tried substituting the $sql variable (containing the statement) with other statements just for test purposes, like for example changing some other fields -- and it works fine. In fact, I tried a combination statement, "update accounts set users=10, loggedin=10 where username='user'" and the users field updates but the loggedin field does not. Both are int(11) columns. And the very same statement works PERFECTLY from the command line. Does anyone have ANY idea? I've been busting my brains and trying all kinds of things -- with NO success. Thank you in advance, Laszlo Szijarto

Re: taxes
This is not as easy (conceptually) as it sounds. You have to know the current state tax plus any county taxes applicable. If you set up a table with this information, you can cross reference the location of the buyer with the table, calculate the appropriate taxes, and charge them accordingly. You must also make sure to record the taxes that were paid so they can be paid to the appropriate tax agency. Not an easy task. There are sources out there for all of this information and you can get tax tables on a CD that can be imported. Brady...

Embedded MySQL: Opinion Please
Hi! I've been monitoring this list for a while now (re: lurking), I've seen only passing comments about embedding MySQL, so I thought I would come out and directly ask the MySQL community for your opinions, or better yet, actual facts - based on experience. I am evaluating MySQL / Linux for use in a line of deeply embedded, multi-node, real-time SCADA products. Where: deeply embedded = headless platform, no user interaction (not even via telnet), no administration interaction, required to operate for years without restart. multi-node = 1 to N processor boards, sharing a common bus (VME, CPCI), not SMP. And, * Database size: between 10K - 250K records - where once the records have been created, they are only updated, typically between several 100 to several 1,000 UPDATES / second. * No moving parts (no fan, no hard disk, no CD, no floppy, no noth'n). * Memory size is not an issue (can add more as required); CPU power is not an issue (re: Moore's Law) (The actual requirements are not as extreme as depicted here, but I want to push the envelope.) I am convinced that MySQL / Linux will work in such as environment. But, the real question(s) is: Can they (MySQL / Linux) work in such an environment, continuously, without error or failure, or requiring operator intervention, for years on end? For this environment, is the MySQL / Linux combo a good idea? Or, should I stick with Linux, but seek out an alternate DBMS? Or, should I drop Linux and go with Windows CE, or some other RTOS? Or, should I stop being a software developing and become a sheepherder?

Urgent Call for Participation
NuSphere has been asked to chair the MySQL track for the upcoming O'Reilly Open Source Conference (July 23-27 in San Diego, CA) and the deadline is virtually here -- decisions must be made by next Tuesday, Feb. 20. This is very short notice but we need your input by end of day tomorrow, Feb. 16. The original call for participation issued by O'Reilly closed on February 1 and some of you may well have submitted presentation and/or tutorial ideas through that avenue. If so, please resubmit those suggestions to me for review. If you hadn't yet submitted a proposal, we urge you to do so now. The information we need is the same as that outlined at O'Reilly's site at: http://conferences.oreilly.com/oscon2001/call.html but instead of sending the submission to them, you'll need to send it directly to me at [EMAIL PROTECTED] And remember, we're solicting specifically for MySQL-related talks and tutorials. Please note - travel and expenses are *not* being covered. Individual presenters are responsible for their own expenses. There is, however, a small stipend for the half-day tutorial. If you have any questions, please feel free to contact me at the number below, or via email.

Index not used for order by when more than 1 field selected, nowhere clause
Hi, I'm having a hard time figuring why mySQL does not use the index when sorting a table without any where clause when I include more than 1 field in the select part. To resume the case, I created a temp table with 3 single fields, added an index (see bottom for more details), ran 2 queries with explain: This one is fine, uses the index: mysql explain select isbn from tmp order by isbn\G *** 1. row *** table: tmp type: index possible_keys: NULL key: isbn key_len: 13 ref: NULL rows: 1000 Extra: Using index 1 row in set (0.00 sec) Adding just an extra field to the select and no longuer is the index used: mysql explain select isbn,author from tmp order by isbn\G *** 1. row *** table: tmp type: ALL possible_keys: NULL key: NULL key_len: NULL ref: NULL rows: 1000 Extra: Using filesort 1 row in set (0.00 sec) When used with the real table which has 160k rows and is called within a complex join that works fine (0.04 sec) and uses index until I add an order by clause, then takes 12secs. Help or hints on fixing the above will probably fix my real problem. Thanks for any help. Further details below, including mySQL version (3.23.30) and OS (RedHat 6.0).

Re: SQL executes on command-line but not in PERL
Thank you, Ryan, but the PERL code runs perfectly if I try it on any other field. It just doesn't run on THIS field. It's not a SPECIAL field in any way (like PRI Key or Unique or anything like that). When I run it in a compound statement like "update accounts set users=10, loggedin=10 where username='user'" -- the users field updates but the loggedin field does not. Both fields have exactly the same definition int(11). Plus the exact same query updates BOTH from the command line -- though only the one field in PERL.

sometimes hanging queries
I've been having a problem for quite awhile now with a particular query
sometimes taking a long time. The query in question is a web-based
search for messages in a bbs archive. Every time a message is added to
the bbs each word in the message is parsed out and added to the
'search_messages_archive' table. It is based on the 'Slapping together
a search engine...' article on phpbuilder.com.
When the query hangs the server load spikes and can cause other queries
to fail.
The tables involved in the query are:
mysql show columns from search_messages_archive;
++---+--+-+-+---+
| Field | Type | Null | Key | Default | Extra
|
++---+--+-+-+---+
| word | char(50) | | MUL | |
|
| message_number | mediumint(8) unsigned | | MUL | 0 |
|
++---+--+-+-+---+
mysql show columns from messages_archive;
+-+---+--+-++---+
| Field | Type | Null | Key | Default

+-+---+--+-++---+
| message_number | mediumint(8) unsigned | | MUL | 0
| |

| |
| message_area| varchar(100) | | |
| |
| topic_number| mediumint(8) unsigned | | MUL | 0
| |
| topic | varchar(100) | | |
| |
| message | text | | |
| |
| post_date | date | | | -00-00
| |
| post_time | time | | | 00:00:00
| |
| user_name | varchar(40) | | MUL |
| |
+-+---+--+-++---+
14 rows in set (0.00
sec)
Here is the query 'EXPLAINED':
EXPLAIN SELECT DISTINCT messages_archive.message_number FROM
search_messages_archive,messages_archive
WHERE messages_archive.message_number =
search_messages_archive.message_number
AND search_messages_archive.word IN ('warmoth')
LIMIT 0,11;
+-+---+-++-++--+-+
| table | type | possible_keys | key
| key_len | ref
| rows | Extra |
+-+---+-++-++--+-+
| search_messages_archive | range | word,message_number | word

| messages_archive| ref | message_number | message_number
| 3 | search_messages_archive.message_number | 19 | Using
index |
+-+---+-++-++--+-+
+
Now here are the results of the query:
From the slow query log (26 seconds):
# Time: 010215 11:24:06

# Time: 26 Lock_time: 0 Rows_sent: 11
SELECT DISTINCT messages_archive.message_number FROM
search_messages_archive,messages_archive
WHERE messages_archive.message_number =
search_messages_archive.message_number
AND search_messages_archive.word IN ('warmoth')
LIMIT 0,11;
The same query run from the command line: (only .39 seconds!)
mysql SELECT DISTINCT messages_archive.message_number FROM
search_messages_archive,messages_archiveWHERE
messages_archive.message_number = search_messages_archive.message_number
AND search_messages_archive.word IN ('warmoth')
LIMIT 0,11;
++
| message_number |
++

| 1675 |
|679 |
| 1021 |
| 1226 |
| 2560 |
++
11 rows in set (0.39 sec)
Even now as I run the query from the web browser again it is very fast.
I just have not been able to track down what causes this query to be so
slow at times and very fast at others.
MySQL version: 3.23.32
OS: SuSE Linux (2.2.10 kernel)
System: PIII w/ 256Mb RAM
Let me know if more info is required
TIA.

Re: Restart server when it hangs?
Hi Alan, Sounds like you need to do some tuning, you are running MySQL low on resources. This is one situation MySQL does not handle well. You need to adjust the login class to have more memory for instance you could create a class named "sql" and place it in your login .conf, then use vipw to change to login class of the mysql user. I have attached an example. You could also just use the daemon class. #Add more relaxed memory for database users sql:\ :path=/bin /usr/bin /usr/contrib/bin /usr/X11/bin:\ :datasize-max=128M:\ :datasize-cur=64M:\ :maxproc-max=128:\ :maxproc-cur=64:\ :openfiles-cur=6000:\ :radius-challenge-styles=activ,crypto,skey,snk,token:\ :stacksize-cur=64M:\ :tc=auth-bsdi-defaults:\ :tc=auth-ftp-bsdi-defaults: On the PHP errors Are you using the latest PHP 4.0.4pl1 or are you using the contrib, I would guess the contrib, try the latest PHP.

Query/Left Join problem
Hi there. I'm having a problem with a couple of tables I'm using and finding some missing records and I was hoping someone could help me. Here is the setup. I have a table that is called "perms". Within here I have a bunch of columns, only 2 of which are important. ID which is an auto increment field and is my primary key for this table. mass_mail which has a value of 'Si' or 'No'. +---+--+ | mass_mail | count(mass_mail) | +---+--+ | No| 2871 | | Si| 8854 | +---+--+ The second table I have is called "newsletter_subscription". This table also has a bunch of columns member_id which is the only important one. There is one record in newsletter_subscription for each record within perms where mass_mail='Si', plus a few records (almost 100) which have a member_id of 0. When I do this: select count(*) from newsletter_subscription where member_id0; I get: +--+ | count(*) | +--+ | 8857 | +--+ As you can see there are three more records in the newsletter_subscription table that should not be (8854/8857). So to find those three records I try this: SELECT newsletter_subscription.member_id FROM newsletter_subscription LEFT JOIN perms ON newsletter_subscription.member_id=perms.id WHERE newsletter_subscription.member_id0 AND perms.id IS NULL; I get: Empty set (0.11 sec) I need to find the three extra records that are in newsletter_subscription and remove them. How would I go about finding them. I also checked the newsletter_subscription table to make sure that it did not have any duplicate member_id's other then the few records with a member_id of 0. The way I did it was to do this: SELECT member_id, count(member_id) FROM newsletter_subscription GROUP BY member_id ORDER BY 2 ASC Then I look at the last couple of lines and see this: | 11922 |1 | | 0 | 73 | +---+--+ 8859 rows in set (0.10 sec) Is there a faster/easier way to do this? something like WHERE count(member_id) 1 (although I know this does not work in that query) Thanks, Roger Ramirez Senior Developer TodoBebe.com - Todo lo que quiere saber de su beb.

Re: taxes
Actually its even more complicated than this. There are city taxes and other taxes on other boundaries. In addition the rules as far as what things are taxable vary by locality. For example, some localities charge taxes on shipping and others don't. Brady Orand wrote: This is not as easy (conceptually) as it sounds. You have to know the current state tax plus any county taxes applicable. If you set up a table with this information, you can cross reference the location of the buyer with the table, calculate the appropriate taxes, and charge them accordingly. You must also make sure to record the taxes that were paid so they can be paid to the appropriate tax agency. Not an easy task. There are sources out there for all of this information and you can get tax tables on a CD that can be imported. Brady...

RE: Index not used for order by when more than 1 field selected, no where clause
Hi, I think you are mis-understanding the information provided. What the "using index" note means is that the isbn column is part of the index, and since that is all that is selected, the index file is used to provide the data, the data file is not touched. Since there is (usually) less data in the index file, and it is more organised, the query takes less time. Adding the author to the query means that the query now has to go to the data file to get the information, and since there is no restriction on isbn, the entire table is scanned for records to provide the result, which is then sorted. If you had an index of (isbn, author), then the index file would still be used. The clue is in the 'possible keys' value - NULL means that no keys are available that would help in providing the query. Can someone else tell me and Francois, when the index is used like this, is the result pre-sorted, so the order by is trivial, or is a sort still performed.

I implemented something almost identical to this setup in 1999. It worked well with Netware 4.11 (with IP enabled on the network) and mySQL 3.22.x running on both a Solaris and FreeBSD box. It should work fine with newer versions of Netware controlling the network. There are the standard integration issues with MS Access (search the myodbc list for these) and some issues with deploying a shared installation of MSAccess on Netware (contact me privately if you want more info), but other than that it went swimmingly well.

Re: Embedded MySQL: Opinion Please

I've been monitoring this list for a while now (re: lurking), I've seen only passing comments about embedding MySQL, so I thought I would come out and directly ask the MySQL community for your opinions, or better yet, actual facts - based on experience. I am evaluating MySQL / Linux for use in a line of deeply embedded, multi-node, real-time SCADA products. Where: deeply embedded = headless platform, no user interaction (not even via telnet), no administration interaction, required to operate for years without restart. multi-node = 1 to N processor boards, sharing a common bus (VME, CPCI), not SMP. And, * Database size: between 10K - 250K records - where once the records have been created, they are only updated, typically between several 100 to several 1,000 UPDATES / second. * No moving parts (no fan, no hard disk, no CD, no floppy, no noth'n). * Memory size is not an issue (can add more as required); CPU power is not an issue (re: Moore's Law) (The actual requirements are not as extreme as depicted here, but I want to push the envelope.) I am convinced that MySQL / Linux will work in such as environment. But, the real question(s) is: Can they (MySQL / Linux) work in such an environment, continuously, without error or failure, or requiring operator intervention, for years on end? For this environment, is the MySQL / Linux combo a good idea? Or, should I stick with Linux, but seek out an alternate DBMS? Or, should I drop Linux and go with Windows CE, or some other RTOS? Or, should I stop being a software developing and become a sheepherder?

Re: Index not used for order by when more than 1 field selected, no where clause
15/02/01 15:14, Quentin Bennett, [EMAIL PROTECTED]: Hi, I think you are mis-understanding the information provided. What the "using index" note means is that the isbn column is part of the index, and since that is all that is selected, the index file is used to provide the data, the data file is not touched. You're right. From Explain doc: Using index The column information is retrieved from the table using only information in the index tree without having to do an additional seek to read the actual row. This can be done when all the used columns for the table are part of the same index. Adding the author to the query means that the query now has to go to the data file to get the information, and since there is no restriction on isbn, the entire table is scanned for records to provide the result, which is then sorted. If you had an index of (isbn, author), then the index file would still be used. That's where I don't get it, I don't want to sort by author, only by isbn. Why does mysql needs to resort to a filesort while it has all the ISBN neatly ordered in an index? Can someone else tell me and Francois, when the index is used like this, is the result pre-sorted, so the order by is trivial, or is a sort still performed. Yes, how can we get mySQL to use an index for doing an order by? Must I create an index for each and every possible fields combination? Thanks for your lights on Using Index Quentin.

I'm having a problem with a couple of tables I'm using and finding some missing records and I was hoping someone could help me. Here is the setup. I have a table that is called "perms". Within here I have a bunch of columns, only 2 of which are important. ID which is an auto increment field and is my primary key for this table. mass_mail which has a value of 'Si' or 'No'. +---+--+ | mass_mail | count(mass_mail) | +---+--+ | No| 2871 | | Si| 8854 | +---+--+ The second table I have is called "newsletter_subscription".

sometimes hanging query - more info
*
I left out a piece of probably important information the first time:
search_messages_archive contains 11.5 million records.
messages_archive contains 760,000 records.
Thanks.

I've been having a problem for quite awhile now with a particular query
sometimes taking a long time. The query in question is a web-based
search for messages in a bbs archive. Every time a message is added to
the bbs each word in the message is parsed out and added to the
'search_messages_archive' table. It is based on the 'Slapping together
a search engine...' article on phpbuilder.com.
When the query hangs the server load spikes and can cause other queries
to fail.
The tables involved in the query are:
mysql show columns from search_messages_archive;
++---+--+-+-+---+
| Field | Type | Null | Key | Default | Extra
|
++---+--+-+-+---+
| word | char(50) | | MUL | |
|

| |
| user_name | varchar(40) | | MUL |
| |
+-+---+--+-++---+
14 rows in set (0.00
sec)
Here is the query 'EXPLAINED':
EXPLAIN SELECT DISTINCT messages_archive.message_number FROM
search_messages_archive,messages_archive
WHERE messages_archive.message_number =
search_messages_archive.message_number
AND search_messages_archive.word IN ('warmoth')

+-+---+-++-++--+-+

| messages_archive| ref | message_number | message_number

+-+---+-++-++--+-+

Now here are the results of the query:
From the slow query log (26 seconds):

The same query run from the command line: (only .39 seconds!)
mysql SELECT DISTINCT messages_archive.message_number FROM
search_messages_archive,messages_archiveWHERE
messages_archive.message_number = search_messages_archive.message_number
AND search_messages_archive.word IN ('warmoth')

11 rows in set (0.39 sec)
Even now as I run the query from the web browser again it is very fast.
I just have not been able to track down what causes this query to be so

Otherwise, you will not receive any future updates. Cyber Digital, Inc. - OUTLOOK Overview Cyber Digital, Inc. (OTC BB: CYBD) is a leading manufacturer, software developer and provider of a vast array of high performance Internet products such as routers, gateways, firewalls and servers for the creation of digital broadband and virtual private network (VPN) applications and services. Cyber Digital is also a manufacturer and software developer of advanced digital voice switching infrastructure equipment for private and public switched voice network operators worldwide, especially for developing countries. The Company's mission is to become the leading provider of: i. digital broadband products in the U.S., and ii. digital voice switches to developing countries. Unlike its competitor's products, Cyber Digital's products are neither labor nor capital intensive but are software intensive. This capability in contrast to that of its competitor's makes its products more affordable for both voice and Internet network operators worldwide. All digital voice switching and Internet Protocol (IP) infrastructure products are based on the Company's proprietary operating system software, which provides high performance, reliability and functionality. Recent Developments * During the year 1999, Cyber Digital forged an alliance with ATT to enter the high-speed Internet access and virtual private network (VPN) markets. Since, then as Cyber Digital has proven its Internet products, the main focus is to market its products through distributors in the U.S. * During the year 2000, Cyber Digital developed its Cyber Business Internet Gateway (CBIG) and Cyber Internet Access Network (CIAN) distribution router. * On November 30, 2000, Cyber Digital enters the Nigerian Telecommunications market to provide 10,000 lines of its CDCO and CTSX digital voices switches for public switched network applications by its lowest offer of $26 million to NITEL in partnership with Sidney Telecommunications (Nigeria) Ltd. * On January 16, 2001, Cyber Digital jointly announced with Sidney Telecommunications their expansion into the PABX market. The initial order for 10,000 CSX PABX reflects approximately $4 million in revenues. * On January 23, 2001, Cyber Digital enters the $5 billion Internet firewall appliance market with the introduction of its Cyber Firewall (CFW) series standalone IPSec (Internet Protocol Security) firewall appliances. Outlook During the next twelve months, the Company expects to derive its revenues from two of its core business segments: i. Domestically, the Company will initiate sales of its firewall and virtual private network (VPN) appliances to small and medium size businesses. The Company expects to ship 1000 firewall units generating $12 million in gross revenue with an approximate net income of $2.4 million; and ii. Internationally, the Company currently has a backlog of $30 million to supply to Nigerian telecom market with its digital voice switches. The Company expects to deliver $30 million of these switches resulting in an approximate net income of $7.5 million. In Conclusion We are uniquely positioned to become the leading provider of digital broadband products and digital voice switches because: * We forged an alliance with ATT to enter the high speed Internet access and virtual private network (VPN) markets thus reducing marketing risk. * Customer testimonials confirm our business model is proven thus reducing business risk. * We have fully developed our CBIG gateway, CIAN router, Firewall and Servers thus eliminating development risk. * Simple do-it-yourself installation software for gateway, router and firewall appliances thus eliminating the need for costly specialists. * Cyber Digital products offer cost savings in excess of 50% over competitors' offerings thus reducing sales risk. * Our broadband solution brings the Internet closer to users thus eliminating bottlenecks, reducing network delays and increasing reliability thus reducing any performance risk. Our solution will make the Internet as reliable as telephone networks. * Captive Nigerian telecom market customer with orders backed by irrevocable letters of credit thus reducing profit risk. * Captive Nigerian telecom market customer wants 2 million lines by year 2003 thus reducing market share risk.

Re: [OT] C program warnning (Just a test i try to understand C in order to build my mysql client program)
Hi.
You know, this question is off-topic on the MySQL list.

Hi folks,
I am trying to compile a simple program to play with mysql. But i am

I am too paranoic when compiling my programs, so i activate all warnning
(at least i try) flags to gnu c compiler.
The problem occurs when type conversion: type conversion is automatic
when a functions takes a single pointer to const anything, but when
there is a double pointer to a const type and i pass double pointer to a
non const type i run into problem? Why in the later case conversion is
not automatic? the former is.
This is a FAQ, see e.g. http://faqs.jmas.co.jp/FAQs/C-faq/faq, section
11.10. For a somewhat better explanation have a look at the C++ FAQ
(and also applies to your C program):
http://reality.sgi.com/austern_mti/std-c++/faq.html#C1
The summary is that one could bypass the const qualifier c() adds (not
in your example, but in general).
Here is the simple code (just to test):
#include stdio.h
int
t(const int *i)
{
printf("%d\n", *i);
return 0;
}
void
c(const char **reg)
With C++, you can declare it as
void c(const char * const* reg)
but this does not seem to be allowed in C (I am not used to C anymore,
but gcc 2.95.3 complains).
{
while (*reg)
printf("%s\n", *reg++);
}
int
main(int argc, char *argv[])
{
int i;
char*reg[] = {
"Gustavo",
"Vieira",
"Goncalves",
"Coelho", "Rios", NULL};
The other way is to declare "reg" to what is really is, instead:
const char *reg[] = ...
This will also work with C.
The solution of the C-FAQ is dirty (as it opens the hole again because
of which the auto cast is not made) and should IMHO be avoided, if
possible.
Bye,
Benjamin.

I want to report the ranking of an album's plays (against all other albums ) for
every city over a time period.
National album ranking for "Beatles #1" between 1/1/2001 and 2/14/2001 :
New York #1
Chicago #2
Boston #1
Miami #3
Right now the current approach involves looping over every city making 2 queries.
First query to get the total # of plays for this album for the time period in that
city. Next query to figure out how many other albums for that city for that time
have total play sums that are greater, which is the Rank.
foreach $cities as $this_city
{
$this_album_total_plays = "select sum(total_plays) from album_by_city
where album_id = $album_id
and city = $this_city
and date = $StartDate and date = $EndDate";
$rank = "select album_id, sum(total_plays) from album_by_city
where city = $this_city
and date = $StartDate and date = $EndDate
group by album_id
having sum(total_plays) $this_album_total_plays";
echo "$this_city $rank";
}
Is there a way to do this with fewer queries or perhaps temporary tables for greater
speed ?

I haven't used EXPLAIN before.
There are indexes on each column.

There are about 100 cities or regions that are used for ranking.

I didn't write the Oracle queries but they used sub selects and all kinds of not

I want to report the ranking of an album's plays (against all other albums ) for
every city over a time period.
National album ranking for "Beatles #1" between 1/1/2001 and 2/14/2001 :
New York #1
Chicago #2
Boston #1
Miami #3
Right now the current approach involves looping over every city making 2 queries.
First query to get the total # of plays for this album for the time period in that
city. Next query to figure out how many other albums for that city for that time
have total play sums that are greater, which is the Rank.
foreach $cities as $this_city
{
$this_album_total_plays = "select sum(total_plays) from album_by_city
where album_id = $album_id
and city = $this_city
and date = $StartDate and date = $EndDate";
$rank = "select album_id, sum(total_plays) from album_by_city
where city = $this_city
and date = $StartDate and date = $EndDate
group by album_id
having sum(total_plays) $this_album_total_plays";
echo "$this_city $rank";
}
Is there a way to do this with fewer queries or perhaps temporary tables for greater
speed ?

Well, I see no principle problem here. The servers I administer run about 200-400 days without interruption (then the counters get interrupted by hardware/software upgrades ;-) Exceptions are massive internet accesses (so called slashdot effect), but with enough memory and some reasonable limits set, one gets even this stuff stable (not responsive, but stable). What you have to have a look at is anything which is incremental, mainly log files and such stuff. Either disable or rotate those. What I would do is make a test install, then leave it alone for some time and then compare all file sizes and assure that the growing files will be no problem or handle them with cronjobs. For case of emergency (i.e. if some program crashes anyhow), there are several solutions for watchers available, which can restart them (although, as I said, I did not need that stuff until now on x86 boxes). For this environment, is the MySQL / Linux combo a good idea? The question is whether the support for your hardware is stable. If so, I would dare to say that I get the software part stable, too. Or, should I stick with Linux, but seek out an alternate DBMS? MySQL is rock solid if you avoid newly added features and have tested your queries once to be supported. I won't say anything about other DBMSes, because I use none intensively enough to justify a opinion on it. Or, should I drop Linux and go with Windows CE, or some other RTOS? Well, I am biased there, but I would really avoid Windows. ;-) Other RTOS are probably a good idea, as someone else already said. Or, should I stop being a software developing and become a sheepherder?

Re: Good tutorial sites
I have got the same confg and works perfect. WinNT Linux MySQL.
Why dont U directly edit the user table of mysql DB.
Let Host be '%' and give some username password.
mysql insert into mysql.user
values('%','username',password('passwd'),'Y','Y','Y');
For test purpose let all priv fields be 'Y'.
Then try again it shud work.
Cheers!

Re: Index not used for order by when more than 1 field selected, no where clause
Hi. On Thu, Feb 15, 2001 at 03:53:39PM -0500, [EMAIL PROTECTED] wrote: 15/02/01 15:14, Quentin Bennett, [EMAIL PROTECTED]: [...] Adding the author to the query means that the query now has to go to the data file to get the information, and since there is no restriction on isbn, the entire table is scanned for records to provide the result, which is then sorted. If you had an index of (isbn, author), then the index file would still be used. That's where I don't get it, I don't want to sort by author, only by isbn. Why does mysql needs to resort to a filesort while it has all the ISBN neatly ordered in an index? You have to look at it the other way around: If MySQL uses the index, it has one of two possibilities. First: 1. Read the whole isbn index, and for each row 2. seek the record in the data file and get author from it. This is quite slow because of the random file seeks needed. Second: 1. Read the whole isbn index (since you have no restricting WHERE clause) 2. Read isbn,author from the whole data file in unsorted order (you need isbn, too, else MySQL wouldn't know where the authors belong too) 3. Sort isbn,autor (using sorted isbn, so using selection sort?) This is still slower than MySQL's approch: Third: 1. Read isbn,author from the whole data file in unsorted order 2. Sort isbn,autor as "Second" additionally has to read the index file from disk with no additional benefit. I don't know how to express that elegant, but the problem is that by including author to the queried fields, you have an unsorted column which requires a full sort. "Second" is never the best way. MySQL uses "First" up to some percentage of the amount of records (30% I believe), then uses "Third", because reading the data in file order (unsorted) and sorting is usually faster than random seeks (due to index usage) over that percentage of records. Can someone else tell me and Francois, when the index is used like this, is the result pre-sorted, so the order by is trivial, or is a sort still performed. If the index is used, the data is read in-order and therefore the sort is skipped, AFAIK. Yes, how can we get mySQL to use an index for doing an order by? Must I create an index for each and every possible fields combination? There are several reasonable approaches and which to use depends on your environment and usage. One is almost the one you propose, but not indexes for all combinations, but only for the common ones (you are restricted in the number of indexes). Since the time difference is quite large, your data file seems to be quite big and you may want to consider to split it into two tables, if the scanned fields (like author,isbn) are relatively small compared to the rest of the record. One table would contain all small fields that are needed in the full table scans and the other table the rest. On the other hand, you may question yourself whether these full tables scans are really needed that much (it sounds rather unusual).
