Re: Can anyone do this ?
Hi Rus, I'm not sure I follow, but the DATE column represents the dates at which I have a certain item in stock. ie (. for from 2001-02-04 - 2001-02-06 I have Item1 in stock. However I only have Item2 in stock on 2001-02-04 AND 2001-02-06). A typical application would be a car hire company: where the Items represent a particular car model. My user requests a list of all cars available from 2001-02-04 to 2001-02-06. I can therefor only return Item1 as Item2 is not available on 2001-02-05. I hope this answers your question.

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.

Hello. On Sat, Feb 03, 2001 at 01:54:14AM +0200, [EMAIL PROTECTED] wrote: Dear Benjamin. I firstly very very thanks for your interest. This is my 3'rd mail with same question and you 're the first one who reply. Well, it might be due to the fact that you have a rather unusual use pattern. [...] Description: I am connecting from Visual Basic 6 to Mysql via ODBC DSN. When i made 94 sleeped connection after 94 can't connect to a server. It says : [TCX][MYODBC]Can't Connect to Mysql Server on 192.9.200.2 (10055) Is it fault of myodbc or mysql server? Is it normal. If there a maximum connection limit for process ? No. Your process is only limited by your OS. E.g. Linux defaults to a limit of 256 sockets per process. I don't know about Windows. I know but i tried it on 1 GB RAM and dual processor PIII 700 MHZ on winnt 4 with service pack 6 a. Well, your resources (e.g. memory) normally don't influence the default configuration automatically. That means, you should consult the usual Window NT resources (web pages, mailing lists?) how to change the process limit. [...] I think it is abnormal cause everyone is talking about 10.000 Web Hit. Sorry? You can handle 10.000 web hits with only one connection. i am not interested about web. it works. no problem. Well, it was your example. ;-) [...] Think a scenario : You connect via ODBC or Data Environment from VB then you get a recordset. You will show this recordset on a grid. (excel style spreadsheet.) if you use additem method , you can loop recordset and manually add rows into grid then close recordset no problem. but if you bound grid into that dao object then until program or form close it run as a sleep process. Well, that's the problem. It is usually (not only with MySQL) a good idea to block resources as short as possible. The suggested program doesn't do that. Even if the connection is idle, it blocks a connection. and if you even use 3 connection for program , if max sleep process is limited to 90 (due to your hardware configuration , but even if you use 1 gb ram it is limited to max 120) that means maximum 30 user will be execute your program. I assume that is only a parameter you have to change within NT. [...] i have a critical product(which is written in vb for end users) that needs at least 150 concurrent sleeped process to run. Well, but 150 concurrent connections may not be a problem even for NT *eg*. So, as said above, I suggest you check out the appropriate NT resources how to change the process limit (in hope that this is really the wall you hit, but it sounds so).

You should run:
automake
autoconf
./configure (with options of your choice)
make
You should use all latest GNU tools for the above, including GNU make,

Re: Web Interface
Thanks to everyone who replied. I got a lot of people who said I should either use phpMyAdmin or webadmin. It turns out that neither will quite do what I need it to, and I just wanted to try to get any other suggestions. In particular, the former doesn't allow one to put any kind of good security on the pages s.t. a user needs a password to do things, w/o a good deal of recoding. The latter requires root access on a server, which I don't have. Does anyone have any other suggestions? There's something written in Perl called "MysqlTool". It looks good.

Re: MySQL constantly crash on BLOB insertions...
Huang-Ming writes: Hi! I just saw this question un-answered, so in case you already got a private answer, please just ignore. hi Tim, thanks for the prompt response which is hard to be seen with Oracle and Microsoft. sorry, i should have had studied hard the manual a year ago. regarding the error, however, would the error message be better to tell users to adjust relevant configuration than only to say "MySQL gone away"? it's misleading to some serious fault in MySQL which actually is not therein, isn't it? There is nothing serious around; it just means that the server has closed the connection to the client because the server assumes that something had gone wrong. This happens, for example, when the server notices that a client is sending packets that are out of order, or too large. Nothing crashes (the server is still running), but the connection was just closed. So actually it is very much true what the server says to the client (the error message). The problem is that there are already some situations when this error can happen, so we thought that it is better to give a short error message than give a long list of possible reasons for the error. One just needs to consult the manual in order to find out a verbose explanation for the happening and the solution.

hi list, i am new to mysql. i have read through the reference-manual but still there are some things i could not answer myself. please help, many thanks in advance. --- mysql-reference-manual describes longblob as a blob column with a maximum length of 4294967295 characters but also says that one cant use this whole range yet. what exactly does this mean? how much can i use? --- chapter 11: "replication" doesnt mention any way of scheduling replication. it says after one configured and restarted the slave server it will connect to the master and then start replication. is there a way to schedule replication? can i start replication at specific times only? --- in chapter 11: "replication" i cannot find any information about replicating blob data (ok: is doesnt say it is NOT possible). can this be done? does anybody have experience in replicatin blob-data (largeblobs)? - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

And if you let me know the most proper mail-address for such feedback mails, i will use that address with pleasure. Now lets turn back to the point; The Winmysqladmin was active and the server was started. Then I wrote a pgm thats creating a database (CREATE DATABASE ...). As a checkpoint i put the error messages statement in my program and i saw that its created and when i try to run the pgm again, i saw the error message saying its already created. Also i created a table in this db and its ok, its created and when i try to run the same pgm, again i took the same message about my re-creation attemp. BUT at the same time i was checking (many times)the Winmysqladmin's databases tab and i couldnt see neither the db i created nor the table naturally. Coincidentially, it appeared later; I wanted to create a db not by sql statement in pgm, but explicitly at the databases page of Winmysqladmin. I tried to create a db with the same name i have created before (and couldnt see on the db page of Winmysqladmin but took the message in my pgm about its existance). Surely i couldnt create and i tried another not-existing db name, it was ok, its created and appeared on the db page of Winmysqladmin. Right at that time i saw that the former one appeared as well! Great! :) Also when i shut down the both server and service and restart them, i saw it appeared. Another point; when i want to shut down both the server and the service, server led(or lamp) is turning to red immediately, its ok...but the administrator icon doesnt disappear for a couple of minutes (in general around 3 minutes), sometimes never disappears. I found out the solution coincidentially: when i get my mouse over the icon, then it disappears immediately! If its a bug, its a very cute one! :) Maybe a little feedback , but maybe useful as well... By the way, thank you for this product.

RE: need some help here...
MySQl does not support FK relationship constraints. meaning that if you put a value in a FK, it won't automatically check to make sure it's a valid value in the related table. You can, however use FK's. That is how you should related your tables. It is up to you, the developer, to make sure that no bad data gets put in them though.

Hello, I am trying to craft a query that will allow me to retrieve truly unique result elements. Here's my setup: table_1 link_field varchar(20) field1 varchar(20) field2 varchar(20) table_2 -- link_field varchar(20) field3 varchar(20) Here's what I've been trying to do (unsuccessfully): "SELECT DISTINCT t1.*,t2.field3 FROM table_1 AS t1, table_2 AS t2 WHERE t1.link_field = t2.link_field ORDER BY t2.field3" imagine these contents of the two tables: table_1 --- record 1: link_foo1 foo1 foo2 record 2: link_foo2 foo3 foo4 table_2 --- record 1: link_foo1 bar1 record 2: link_foo1 bar2 record 3: link_foo2 bar1 What I want is a query that will return only 1 entry for each "link_foo" encountered in table #2 but order the result based on the contents of "field3" from table #2 and also return the corresponding data from table #1. The query I'm running shows a number of records returned equal to the number of records in table #2... although they ARE ordered correctly. What am I doing wrong? If there's no way to do what I want I suppose I could keep a list of each item encountered and skip over the next element if it has already been encountered but that seems like a lot of extra unneccessary code.

Hi Rus,
I'm not sure I follow, but the DATE column represents
the dates at which I have a certain item in stock.
ie (. for from 2001-02-04 - 2001-02-06 I have Item1
in stock. However I only have Item2 in stock on
2001-02-04 AND 2001-02-06).
A typical application would be a car hire company:
where the Items represent a particular car model. My
user requests a list of all cars available from
2001-02-04 to 2001-02-06. I can therefor only return
Item1 as Item2 is not available on 2001-02-05.
I hope this answers your question.
Thanks,

out how to do the following:

I have allocations greater than one for all days
encapsulated between the user input range.

| 2001-02-04 | 2 | 2 |
| 2001-02-06 | 1 | 2 |
++-+---+
Basically my user says he/she needs a list of what
items are available FROM a certain date TO a
certain
date. I therefor need to return all items which I
have at least 1 of for EACH of the dates within my
users range:
I have tried using BETWEEN but it fails (ie.
If my user says: from 2001-02-04 to 2001-02-06,
using
BETWEEN MySQL returns Item2 even though I do not
have
Item 2 listed for 2001-02-05.
Here is where I'm at:
mysql SELECT t1.*, t2.*
- FROM Table1 t1, Table2 t2
- WHERE t2.date BETWEEN "2001-02-04" AND
"2001-02-06"
- AND t1.id=t2.table1_id
- AND t2.no_of_Items =1;
++---++-+---+
| id | Item | date | no_of_items |
table1_id |
++---++-+---+
| 1 | Item1 | 2001-02-04 | 3 |

| 2 | Item2 | 2001-02-04 | 2 |
2 |
| 2 | Item2 | 2001-02-06 | 1 |
2 |
++---++-+---+
What I need is a query which will generate the
following result:
++---++-+---+
| id | Item | date | no_of_items |
table1_id |
++---++-+---+
| 1 | Item1 | 2001-02-04 | 3 |

| 1 | Item1 | 2001-02-05 | 2 |
1 |

Installing binary distributions in non- standard locations.
I have been trying to install 1.3.23.29-solaris 2.6 binary distribution. But as a neophyte to MySQL I cannot seem to start the client software. I have varied from the standard procedure (By necessity) to install it to a non-standard directory (/ss/mysql) so I have had to add the --defaults-file=/ss/mysql/data/my.cnf flag to the various commands. so I have successfully started the safe_mysql command with the defaults-file flag. When I type the suggested mysqladmin --defaults-file=/ss/mysql/data/my.cnf -u root -p 'password' I get an access error: mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user: 'root@localhost' (Using password: YES)' I am confounded by this, since the same procedure for linux worked perfectly. (differing directory root.) Does this look familiar to anyone? thank you, Jack Summanen - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: Setting up data model
If you mean you link table techadress to table domains, and then billing admin adress to techadress, then i think you'r odd.. You should learn some about 'normalization', look for it on the web or in a book. I'd suggest something like this: Customer client_id clientaddr_id ..details... Domains domain_id client_id//references customer techaddr_id//references addresses billaddr_id// " adminaddr_id// " name type ...info... Adresses address_id type name addr city country .etc... If you'd like to have more than three addresses, you just add an extra table, and skip the '..addr_id' 's from domains: domainaddresses da_id domain_id address_id type This table then links the domain to n addresses. good luck, rene - Original Message - From: "Kevin O" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, February 05, 2001 6:31 PM Subject: Setting up data model Hello all, I've got a few questions about setting up a data model for a database I'm creating. I want to set it up to be most efficient and would like input from anyone that has the time. I'm setting up your basic customer database, except I'd like to allow for a customer within a customer option. Not everyone will have this, but for those that choose to, it will be available. Here is basically what I have: 1) I'm a web hosting company and would like for each customer to have the ability to have multiple domains under their account. (this is the easy part, just a basic customer database) 2) Each domain however will need the ability to have up to 3 addresses associated with it. For example, Administrative, Technical and Billing Contacts. Now, the question is how do I set this up to be the most efficient storage of the data? My thought is Main Customer Table | | Domain Table | | TechAddress Table-- --AdminAddress Table | | BillingAddress Table Am I way off here? I will be checking for things like if each of the addresses being entered are the same as the main address in the main customer table. I know this is very confusing. Can someone please help?

Ooops, I forgot to notice that you required consequetive days. This query works for me: select T1.*, T2.*, count(T2.id) as c, concat(T2.id,T2.d) as x from table1 as T1, table2 as T2, table 2 as T3 where T1.id=T2.id and T2.id=T3.id and T2.d='2001-02-04' and T2.d='2001-02-06' and T3.d='2001-02-04' and T3.d='2001-02-06' group by x having c=3; Uglier, but seems to work ok. Of course, you'll have to change the having c=3 part to refect the number of days in the interval. Or maybe there is a mysql date subtraction routine for that... What I need is a query which will generate the following result: ++---++-+---+ | id | Item | date | no_of_items | table1_id | ++---++-+---+ | 1 | Item1 | 2001-02-04 | 3 | 1 | | 1 | Item1 | 2001-02-05 | 2 | 1 | | 1 | Item1 | 2001-02-06 | 2 | 1 | ++---++-+---+ _ Do You Yahoo!?

There is no server-side cursor handling on mysql so unless you
are using something other than MyODBC to emulate cursors you must
treat all recordsets as static.

query questions
Hi all, I have a few questions about query structure. 1. COUNT(*) Is there anything wrong with using SELECT COUNT(*) FROM bleah or should I be using SELECT COUNT(someField) FROM bleah 2. Is two queries a lot less efficient than one? Background: I have a table with about 20 fields of business Information. How much information needs to be displayed depends on what "packageID" the business has. So, if I look at all the business is one category, I may get 20,000 records returned. However, only 10 of those may need all twenty fields returned. Currently I'm using one query, SELECT * FROM business WHERE categoryID='$categoryID' LIMIT $pageStart, $pageEnd //this is to only return five records per page But in one case, where I have to join two tables, the temporary table it creates is too big. Would it be a lot slower to say: SELECT * FROM business WHERE categoryID='$categoryID' packageID='1' LIMIT $pageStart, $pageEnd Display these results, using a counter to keep track of how many are returned (in case less than 5 are) Then do another query SELECT (here list the fields necessary) FROM business WHERE categoryID='$categoryID' packageID='2' LIMIT $counter+$pageStart, $pageEnd Hope this makes sense.

update log sequence
I'm running mysql with --log-update=update_log with no extension, so every time I flush the logs I get the next sequential number appended as an extension to the new update_log file. If I flush the logs regularly every day, that sequence number will continue to grow - is there any way to reset the update_log sequence number back to .000? How big will it grow? Will it ever recycle itself? TIA.

Simple question
Hello, I always wanted a gui interface to use on my win 98 pc to connect to mysql, and create/edit tables. However, i always get an access denied error, saying I'm not allowed to connect to the mysql server. However, via telnet, I am fine. The support for the software sucks, and all the other programs I have tried suck, don't work, or are in german. What gui interface is good to connect to a mysql server to create/edit db's/tables, and if you use it, how in the world do you connect? I can connect to the server via telnet. Just fine. But via the software, I get permission denied. Any way I can set it up on my server to allow such a connection out of telnet? Thanks Joel
Re: Multiple AND on many-many-table.
Steve Ruby wrote: Does anybody know what is the fastest way to run a large multiple AND type query on a many-many table and the least memory hungry. For example if I have create table test (id int, value int); which has many-to-many on id, and value I want to do a select like select id from test where id in (select id from test where value in (1,2,3) and id in (select id from test where value in (4,6,7) and id in (select id from test where value in (1,6,25) So I must return users that qualify for at least one value in several lists, obviously this is somewhat easy with subselects... Without subselects I'm doing this, can anybody tell me of a better way? create table temp (id int not null, key (id)) type=heap; insert into temp select id from test where value in (1,2,3); insert into temp select id form test where value in (4,6,7); insert inot temp select id from test where value in (1,6,25); select id from temp, count(*) as numlines from temp group by id having numlines = 3; drop table temp; there will be anywhere between 1 and 10 of the above lists for this query so then I return the qulified useres by doing this on the heap table where the having part is equal to the number of lists that were checked. Obviously the temp table can get very large depending the query, currently this seems pretty fast, but I'm concerned that it will blow up on me as I get more id values anybody know a better way? A self join comes to mind but if there are many users and say 10 questions then the length of the self join result before the WHERE is userlines^10 which can be a very big number. Not knowing how HAVING is optimized i've decided for now to go with one table per question (each of the ANDs) and do a join (max of 10way) against a temp table for each question... still doesn't sound like the best route but it will have the same amount of data in it as if I did one big table and seems like it would be quicker to update the keys on the smaller tables better ideas appreciated. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: need some help here...
Just my opinion, but I prefer numeric keys that the users *can't* see, to alpha keys that the users can see: 1. numeric keys are faster 2. using numeric keys that the user can't see allows you to open up(for UPDATE) ALL the fields that the user can see including a field like School Name. Problem with alpha School Name: If you allow the users to change the school name, you'd have to change *ALL* occurrences of the old school name to the new school name - in all tables/rows that reference the old school name - could be a big programming effort. If you don't allow the users to change the school name, they might be unhappy - or maybe you allow users to submit a form saying they want to change school name from a to b, and you write a program which goes through the database changing every occurrence of a to b. Again, a lot of work, and users who are probably unhappy. Solution: Instead of having the School Name be your primary key, have a field called school_id that the users can't see or update - once assigned to a school, that school_id is the primary key to that school's info forever. If another table/record needs to refer to a particular school, you store the school_id in that table/record, instead of storing the school name. Since the users can never update the school_id, you don't have to worry about writing extra code to update all the occurrences of a to b - you can then allow users to update the school name field without affecting the key - the school name is just another data field. This may not be the best example for me to demonstrate why I think numeric keys are better - maybe in this case the School Name never changes for any of the schools. But if it could change, then numeric keys could be the answer. MySQL auto-increment fields are great for this, and Oracle has a similar type of field called a "sequence". Where it makes sense, my preference is to use an auto-increment INTEGER field as the primary key to a table. Keeping the numeric keys used for basic retrieval separate from the user viewable/updatable fields makes for a smaller, less-complex, and more flexible program. Again, just my opinion.

Only degrees have a number as the key, with School name and the key of the previous table entered as fields, to link everything together.

Query Help
Hello, I have a table of 26 million rows that I need to query. The table is a keywords database with the keyword and a pointer to what page it came off of. (pageid|keyword) The problem is that when I use the following query is the group by make the query take about 14 seconds to do. However, if I remove the group by portion it finishes the query in less then .10. Here is the query: SELECT count(pageid) as n, pageid FROM keywords left join deleted_keywords on keywords.keyid = deleted_keywords.keyid where deleted_keywords.keyid is null and (keyword = 'Big' OR keyword = 'Brown') group by pageid having n = 2 limit 100; I need to be able to query the database and only return pageid's of pages that have every word on it. The left join is used so that I do not have to delete from the database all day, I just do a flush once a day in the wee morning hours. This table gets queried about 600 times a second, so having a 14 second query creates such a backlog that the system becomes unusable. Any help would be really appreciated.

Re: Re[2]: Serious MySQL internal deadlock
Hi,
unfortunately I can't set up a scenario that easily reproduces the problem. The
last lockups happened on saturday and today (monday). What I can confirm is:
1. It doesn't seem to be a slave related problem. During the last two lockups I
checked the master as well as the slave statuses, all were in sync. I then
issued 'slave stop' on both slaves, killed the master (TERM), restarted it and
then issued 'slave start' on both slaves then continued syncing just fine.
2. The lockup always happens when there's a concurrent insert and a query.
Today I just looked at some performance statiststics (a web page with 6
generated performance graphics) when the lockup occured. 5 of the 6 graphics
were complete, the last one didn't complete and the database lockup was back
again.
What I could do would be to send you the database schema and some of the php
report scripts.
Fortunately I managed today to react fast to retrieve the process list
(attached). Looking at it, could it be that the problem occurs when a query is
processed on a table and more than one insert to the same table is pending?
The termination of id 584 didn't help. All further inserts were stuck in state
'System lock' (all but 1) or 'Opening table' (1, this was the successor of id 2
which I killed to test what would happen after a reconnect) and all further
queries were stuck in state 'Opening tables'.
As a remainder: I already tried mandatory write locks for the inserters and
mandatory read locks for the queriers which didn't help.
I didn't check, if more than one database is affected by the lockup.

Is it a bug???
I have been using MySQL for ecommerce work for quite some time. One problem that just recently arose was a duplicate key error during db restoration. The culprit lies in a table which has an auto_incremented, not null defined integer field called "id". There is an entry which was adjusted, by me, to have an "id" of 0 (instead of 1). When mysql attempts to restore this table, after a backup, it complains that the entry (which previously had the "id" of 0) now has an "id" of 72, and is invalid as there already is an entry with an id of 72. Basically it seems that restore cannot allow for a zero value, if the field is an auto_incremented, not null primary key. This seems like a serious problem, since many ecommerce table designs use a zero value in such a table to represent a catalog base. Is there any solution in mysql?

Get 'yes', 'no', or 'either' query ?
Hi. Hey I have been using a query in a search with prioritized criteria. In five different qualification fields, the first one filled in would produce the specific search. Name, City, Zip, (C)enter or (I)ndividual... If name city empty and zip filled in, all that zip would appear. No problem. Now I have a situation where I do not want *all* zips to appear but only those belonging to either (C)enter *or* (I)ndividual. That is still no problem. That is simple 'zip' *and* 'type'. But now, if 'type' can be *either* (C) or (I), and we want to see *all* the zips, I get lost. It seems like it should be simple but I cannot make a third option of the input form to look for *either* in the same query. This is to be done for 3 out of the 5 fields in the same input form. I could probably do it with *lots* of if/thens but I'd rather not if possible otherwise. Can someone suggest something. Thanks much, in advance.

WEB to remote MySql server
Hello, I would just like to ask the list's members of this setup: We have rented a Win2000 web server in the US with a 50GB transfer/month in the internet. The server currently holds our site's asp web files, SMTP/POP server and MS Access database files. The Access files holds the list of users of our asp pages and allowed email users. Our web application presents a login form which is checked against the list of users in the database. Everytime a member logs in or signup, the Access database will be used. Over here in the Philippines, I have several servers each more powerful than the one in the US except that our internet connection is only 128kbps with burst of up to 256kbps. I plan to distribute the load of the US server by moving some of the services to our local facilites. Will there be connection problems if I move the database to a MySql server to our local site an still retain the web server in the US? Or is it better to have MySql running in the US server and have a duplicate or slave MySql server here in our local site. I also plan to move the email servers here and email users will also be checked against the database. Thanks in advance. * Jonor Lacuesta Systems Administrator Philippinemail.com "Send free postal letters to the Philippines FREE" http://www.philippinemail.com - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?
