Re: Addnew problem
are you using something like this? ::
set dbconn = server.createobject(ADODB.Recordset)
dbconn.open dsn=yourdsnname;uid=;pwd=;driver=mysql
sql = SELECT * FROM tablename
recordset.open sql, dbconn
insert = INSERT INTO tablename (column1, column2) VALUES
('valueforcolumn1', 'valueforcolumn2')
dbconn.execute insert
It's much easier that way. 2nd Question: The only thing I can think of is
if you are using a WHERE clause. You must be new to this. (by the way,
cool name dude). Make sure that database is connecting and you have the
right recordset settings.

Subject: Addnew problem
Hi,
When i create a webpage in frontpage in ASP code, de Addnew function to
add
a record in my mysql database does not function properly.
The record is inserted , but the other first existing record will be
deleted.
What is going wrong here ?
ALso when i create a new database with a column ('test') for example, it
is
not possible to add records when the database is empty, so i have to
manualy
add a record in the database first.
What is here the problem.
thanks
Vincent de vilder

Same Sockets problem for MySQLGUI but with a different twist.
First - I read the Readme file several times. Second - I went though your listserv where you very politely redirect everyone to the Readme file Third - I'm a newbe to linux and MySQL (Microsoft'er looking for the other world) and I don't know what a socket file would be called or where I would find it. I've searched the drive using whereis and looking for sock or socket but I don't find anything. Could anyone take mercy on a Win2K geek and give me step by step instructions on finding or building this sockets file. Maybe I'll convert completely one day :-) Cheers, Randy - 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?

How to use JOINS
OK, well, mysql has LEFT JOINS, right? OK then, in that case, how the heck do I use them?! I need to join 14 tables (with the exact same structure, columns) together and view all of there contents with a WHERE clause like this: SELECT * FROM t1, t2, t3, t4, t5, etc ORDER BY date DESC or SELECT * FROM theworks WHERE userid = 'userid' Any suggestions?

JOINs are used to bring together related records (related in the RDBMS sense of related) into larger records composed of columns from each table. A UNION allows you to treat several similarly structured tables as if the are one large table. MySQL doesn't yet have UNIONs (4.0 will), but it does have MERGE tables which allow you to combine several tables into a sort of virtual table against which you can write queries.

Video game programming????
Hi I was just browsing thru the amazon.com site and just happened to read a customer review on the MySQL (other new riders) book by Paul DuBios and Michael Widenius. It has a wierd review from someone which says I was extremely dissapointed to say the least. This book doesn't even begin to cover **video game programming in mySQL**, not even the basics. In fact, it doesn't cover **video game programming at all**. . blah blah . The line that caught my attention was the one which are inside the ** symbols. Now, this was something new to me.So, i just thought if anyone could tell me more on this. What's video game programming got to do with MySQL ?? and what does he mean by this.

Also, it looks just like marketing talk so i refuse to form an opinion from that. I beta tested Gemini before things got interesting. The technology *is* good, but it's also rather controversial (as you've noticed). So could somebody more enlightened than me please fix us up on the technological benefits/drawbacks on these table types? Gemini provides crash recovery, record-level locking, and high levels of concurrency (as their documentation probably says). It really does work--or did when I last tried it. Also, I would very much love to hear about these legal problems. mysql.com still says But the products they [NuSphere] have shipped are and continue to be in GPL violation.. Nusphere gives you an Gemini GPL Source download. One of the two must be wrong :-)) Let's just say that it's rather complex. The mail archives for this list already contain a fair amount of information on the topic. And there's a lot of information that you simply won't get until the legal stuff is all over.

Thanks Will, to avoid further misunderstandings - the escapefeature of backslash is fully understood. The problem is that the 3d party sw or the myODBC doesn't understand that the inbound text SHOULD HAVE backslash but does exactly whats expected - escape the next char. What I'm asking is - is there any configurable way that ODBC can be made to add that extra escaping backslash needed other than recompiling ODBC which isn't an option for the moment. anyone have clue !?? again, thanx in advance peter Will French [EMAIL PROTECTED] 09/12/01 10:20AM mySQL sees back slashes (\) as escape sequence characters.

Re: MySQL on Mac OS X?
I haven't run mysql personally on my OS X box yet but I do know of some who have and there seems to be a current problem with getting mysql to quit properly. I think that will be fixed with Mac OS X 10.1 which is coming out sometime this month. Other than that go to www.versiontracker.com and click on the OS X section and do a search for SQL you will find a lot of tools to help you out.

RE: Video game programming????
database, sql, query, table database, sql, query, table (I hate 123box.co.uk) Im not gonna go into long discussions of game programming in here. But the reason most people dont use a database backend for most modern games is more a matter of speed than anything else. You cant get an average of over 45fps in anything but a simple game, if you are storing the data in a database. Its much faster to use a c++ class, or good old c struct to store data than use an interface to a database. Im sure there are many types of games where a database would be suitable. But most 'video games' are all about high-speed constant action which require incredibly fast data processing. Im not against MySQL at all, its great for my work requirements, im just not sure its suitable for a 'video game'.

SUPPORT FOR UNICODE
Hi everyone, I am not a user of MYSQL yet, but shall be soon. I needed to know if MYSQL has begun to support UNICODE (UTF- 8) as rest of the RDBMS' have adopted it to meet the language needs of non-english countries. And I am just hoping that amongst so many MYSQL users probably some one would be having first hand information. pls do tell thanks, Priti - 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?

I need that join. WHY? Because it's ambiguous if I dont have it. I'm not entirely sure, but it sounds like you might be confusing a JOIN with a UNION. JOINs are used to bring together related records (related in the RDBMS sense of related) into larger records composed of columns from each table. A UNION allows you to treat several similarly structured tables as if the are one large table. MySQL doesn't yet have UNIONs (4.0 will), but it does have MERGE tables which allow you to combine several tables into a sort of virtual table against which you can write queries.

Re:error in sec index entry update
Brian, the error message means that you updated a secondary key of a row but InnoDB did not find the index entry in the secondary index. The bug may be due to an error in purge, insert buffer, or the buffer pool. I am currently running tests on this and studying it. Could you please run CHECK TABLE on the table webassign.rosterInnoDB and send the output to me? Also the CREATE TABLE statement would help in hunting the bug.

Re:ERROR 1073: create InnoDB tables!
Hi! You can probably circumvent the problem by adding an extra VARCHAR column where you put the first 255 characters of the blob column. Or maybe you could generate an artificial primary key with auto-increment, for example? Regards, Heikki http://www.innodb.com Hi, I tried create table specify type=InnoDB.with the following script: create table objects(uri blob not null, primary key uriIndex (uri(255)), classname blob) type=InnoDB;I'm getting the following error ERROR 1073: BLOB column 'uri' can't be used in key specification with the used \ table typeThis is what I found in the mySQL docs: * Only the MyISAM table type supports indexing on BLOB and TEXT columns. When putting \ an index on a BLOB or TEXT column you MUST always specify the length of the index: CREATE TABLE test (blob_col BLOB, index(blob_col(10))); I could change the uri to varchar but... * Values in VARCHAR columns are variable-length strings. I can declare a VARCHAR \ column to be any length between 1 and 255, just as for CHAR columns. That's not very good, we can choose- transactions but uri limited to 255 chars - no limit but also no transactions Is it supported ? If yes, please let me know how?Any help is welcome. - 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?

Crash Recovery
I have a table with over 26 million records that experiences a high volume of traffic. Recently, query results became a little screwy; upon investigation it was found that the table and the index were fouled up. The results of an isamchk on the table yielded: Checking ISAM file: /usr8/hydrology/measurement Data records: 27034726 Deleted blocks: 0 - check file-size ./bin/isamchk: warning: Size of datafile is: 11 Should be: 3554138 - check delete-chain - check index reference - check data record references index: 1 ./bin/isamchk: error: Found key at page 1024 that points to record outside datafile ISAM-table '/usr8/hydrology/measurement' is corrupted Fix it using switch -r or -o and on the index yielded: Data records: 27034726 Deleted blocks: 0 - check file-size ./bin/isamchk: warning: Size of datafile is: 11 Should be: 3554138 - check delete-chain - check index reference - check data record references index: 1 ./bin/isamchk: error: Found key at page 1024 that points to record outside datafile ISAM-table '/usr8/hydrology/measurement.ISM' is corrupted Fix it using switch -r or -o Trying to fix the table as suggested results in the datafile being reduced to a file size of 0 bytyes. Before the fix it is over 4Gigs. I have tried several different options for isamchk including the --quick,which does not kill the data file but still does not work. So the question is: since the isamchk can detect the 27 million records, what is my best hope for getting them all out. select * results in garbage any thoughts would be appreciated. I can get about 90% of the records out with carefully crafted where clauses, but I am a little concerned with the integrity of them. What is the probability that the integrity of these records can be trusted. They look ok and a few random checks that I have done show no problems. thanks to all. Kevin Kotun, P.E.

Re: error in sec index entry update
Brian, your table seems to get corrupt only temporarily. It suggests I have a bug in the interplay of UPDATE and purge. Probably no need to reimport the table. About keys: there is no need to define the same key as the primary key and a non-primary. Thus the key roster_ is unnecessary. Thanks for the info.

If your problem truly is disk I/O, you can try using the InnoDB table type, which caches both index and table data in memory. -- Dan Nelson [EMAIL PROTECTED] - 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?

Copying from one table to another.
Hello, I'm new to MySQL, so forgive my ignorance. I'd like to copy data from one table to another. I have one table I've made from a filemaker database. And one that contains my main data. I want to update the main data from the Main file using the data from the filemaker file. Each row has a unique zip code, and the zip code is in each of the files, so I thought I'd use that as an index field, but with no luck. What I've tried so far is this, and it doesn't see to work. Update tbl1 set CategoryInTable1 = CategoryInTable 2 where ZipInTable1 = ZipInTable2; I've also tried: Update tbl1, tbl2 set CategoryInTable1 = CategoryInTable 2 where ZipInTable1 = ZipInTable2;and Update tbl1, tbl2 set tbl1.CategoryInTable1 = tbl2.CategoryInTable 2 where tbl1.ZipInTable1 = tbl2.ZipInTable2; I thought to do an Insert-Select, but I can't since I want to update the table I'm selecting from. Any help would really be appreciated.

RE: Can't get MySQL to use available memory (performance very slow)
I believe the answer will be for you to create a single index on *just* the cust column. (I assume that a specific cust id occurs only once or a few times in the whole table.) This will allow MySQL to use that index to find the small set of records (quickly) where cust=1, then to screen the email value against that set of records.

Kevin: A database is, in some sense, a container for your tables. It sounds like you want to compose a new container. Thus, To list your databases (containers): mysql show databases; ... it seems that the list should contain your dbb and mysql, probably also test. To create a new database (container): mysql create database new_dbb; Next, you would be able to use new_dbb; and begin creating tables in it, using the 'create table' SQL statement.

Re: Copying table V.2.0
I think you need a new approach. It appears that update does not support the join you are attempting. It seems that you are trying to update the value for a column from one table with the value of a column from another table.

Urgent Assistance
Hi group,
I am in need of assistance with a database and php query we are trying to
achieve.
Basically we are have a form where one field searches a field in the mysql
database and the other searches for keywords using the MATCH query.
What we need to do is for the user to be able to enter a date or keyword and
for it to query the database. Is it possible to do alternate queries based
upon what the user is entering. So we would like to be able to do a sql
elseif statement, but I am unsure if this is possible.
Here is out current code:
$sql= SELECT *, MATCH (auction, email, website) AGAINST ('$keywords') AS
score FROM ukcalendars WHERE date = '$date' HAVING score != 0 ORDER BY score
ASC LIMIT $limitvalue1, $limit;
But we need to be able to also do:
$sql= SELECT * FROM ukcalendars WHERE date = '$date' LIMIT $limitvalue1,
$limit;
But I am unsure how I can achieve this, if at all possible.
With thanks

Comparing Dates
I have a date comparison problem that I'm sure is simple enough but I'm just
not experienced enough to figure it out. I simply want to grab every entry
in a given table that has been entered within the last three days.
I'm using Perl so I first start with a Perl timestamp and convert it to a
MySQL timestamp.
($sec,$min,$hr,$mday,$mon,$year,$wday,$yday,$isdst) = localtime(time);
$year = $year + 1900;
if ($mon = 9) { $mon = 0$mon; }
if ($mday = 9) { $mday = 0$mday; }
if ($hr = 9) { $hr = 0$hr; }
if ($min = 9) { $min = 0$min; }
if ($sec = 9) { $sec = 0$sec; }
$currenttime = $year$mon$mday$hr$min$sec;
Now I want to select all entries that are = ($currenttime - 3 days)
It would work most of the time if I just subtracted 300 from
$currenttime, however wouldn't things get messy at the beginnings of every
month? For example, with a good, regular date like 20010915103934
(09/15/01), subtracting 300 would give me 20010912103934 (09/12/01).
That would work. However, if $currenttime = 20010901103934 (09/01/01) and I
subtracted 300, I would get 20010898103934 (08/98/01). See, that would
be completely screwed up.
How can I accomplish my goal? Please forgive the MySQL newbie for his
stupidity.
Thanks,

I am trying to create a MySQL SELECT statement using PHP where I am
getting a filtered list back by a date in the database formatted as
-mm-dd where the date falls between a one week window that is in
constant motion.
For example, take todays date (as a julian calendar number) and a
date that is set 7 days in the future (also as a julian calendar
number and find all rows in the database where the date field (as a
julian number) falls between the julian number of the window, i.e.
today and one week from today.
The SELECT statement that I came up with is this
SELECT *,DATE_FORMAT(birthday,'%M %d'),
DAYOFYEAR(DATE_FORMAT(birthday,'$yr-%m-%d'))
FROM table_name
WHERE DAYOFYEAR(DATE_FORMAT(birthday,'$yr-%m-%d')) = $yday AND
DAYOFYEAR(DATE_FORMAT(birthday,'$yr-%m-%d')) = $yday_hi;
The PHP variables $yr, $yday, and $yday_hi are set as
$yr is the current 4 digit year
$yday is the current julian calendar date for today
$yday_hi is the julian calendar date one week in the future.
You're making this way too hard, I suspect. To find all birthdays from
a target date to the target date plus a week, do this:
... WHERE birthday = $target_date
AND birthday = DATE_ADD($target_date,INTERVAL 7 DAY)
This select statement works fine until I get to December 24th of any
year, and the $yday_hi goes beyond the actual number of julian days
in this year. So I have created an if statement that says if the
date in the future is bigger than the julian date for December 31 of
this year, then subtract the 2 and set the date in the future as the
difference.
For example, if there are 364 days this year, and today's julian
calendar date is 360, the one week in the future would be (360 + 7)
or 367. So subtract 364 from 367 which is 3 and set the $yday_hi
variable to 3.
This makes the numbers work. So if today is December 30th (or 364)
the week in the future date would become Jan 6 (or 6 as a julian
date).
It is at this time that the select statement look like
SELECT ... WHERE birthday = 364 (today) AND = 6 (one week from today)
My select statement will ONLY work if $yday is smaller than $yday_hi.
Is there a way to make MySQL understand that I need dates at the end
of the year, and at the beginning ??
I hope that makes sense.
Chad

Re: MySQL: Unable to save result set
That error message is coming from PHP, not from MySQL. PHP generates that error message when, for some reason, the number of fields returned by a MySQL query was greater than zero, but the return from mysql_store_result() or mysql_use_result() was zero or NULL. The PHP code which checks those values is very dependent on the version of MySQL you are using. The check for valid fields is different for version before and after MySQL 3.22.24, and the query execution is different before and after MySQL version 3.21.99.

For example if you have a table CREATE TABLE xyz ( c CHAR(30) NOT NULL ) Then you can rename c to d like this: ALTER TABLE xyz CHANGE c d CHAR(30) NOT NULL To answer your next question :-), no, you can't do it without repeating the column definition. - Deryck H - http://www.comp-u-exchange.com -- Paul DuBois, [EMAIL PROTECTED] - 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?

Designing a recovery plan for MySQL
I got an idea and thought i would ask around about a recovery plan about databases? Currently all i do is dump the databases on to a share on an NT box thru a SMB share from the RH 7.1 Linux DB server. The NT box is a Compaq CL1850 which is 2 Compaq 1850 server with a shared SCSI array. The NT box is backed up on a 6 hour interval.

SQL Expert Needed
Hi Guys, here goes..
SELECT count(page_searchwords.word_id) as score, page_data.id, filename,
title FROM page_data, pagewords, page_searchwords WHERE
(page_searchwords.media_type='static' AND pagewords.id =
page_searchwords.word_id AND page_data.id = page_searchwords.id AND
LCASE(pagewords.word) LIKE LCASE('%hit%')) OR
(page_searchwords.media_type='static' AND pagewords.id =
page_searchwords.word_id AND page_data.id = page_searchwords.id AND
LCASE(pagewords.word) LIKE LCASE('%two%')) GROUP BY page_data.id ORDER BY
score DESC;
Hi Guys, above is one of the SQL queries my PHP codes makes up to search my
database. That is what it looks like for a two words search, i.e. hit two.
It looks like the following when it does a one word search, i.e. hit
SELECT count(page_searchwords.word_id) as score, page_data.id, filename,
title FROM page_data, pagewords, page_searchwords WHERE
(page_searchwords.media_type='static' AND pagewords.id =
page_searchwords.word_id AND page_data.id = page_searchwords.id AND
LCASE(pagewords.word) LIKE LCASE('%hit%')) GROUP BY page_data.id ORDER BY
score DESC;
I'll now explain the tables to you.
I have the follwing tables in my database.
table: page_data table: pagewordstable:
page_searchwords
++--+---+-+ ++-+
++-++
| id | filename | title | contents | | id | word|| id |
word_id | media_type |
++--+---+-+ ++-+
++-++
| 1 | 01_title | ABC | information | | 1 | wtc || 2 |
1| static|
| 2 | fileAA | foo | wtc | ++-+
++-++
| 3 | foobar | bar | content | | 2 | information || 1 +
2| static|
++--+---+-+ ++-+
++-++
It works like this.
page_data has the webpage information in it, when the page get's update the
SQL I have written get's all of the keywords from the page. It then get's
the id's from the pagewords table (i.e. pagewords.id), adding the words if
it is not already there. Then once it has all of the id's from pagewords
(i.e. pagewords.id) it adds the information to the page_searchwords table.
The page_searchwords.id column contains the equivalent of the page_data.id
column. page_searchwords.word_id is the equivalent of the pagewords.id
column and the media_type is any of the following three strings; static,
pdf, news.
The search works like this it. It sorts through the page_words table and
get's the id of the words the user is searching. In the example above if the
user search's for wtc and information, the id's it would retrieve are 1 and
2. Once it has these id's it then searches the page_searchwords table and
retrieves any row which has a word_id value of either 1 or 2 (being wtc or
information respectively). Once it has this it then write the search results
out to the browser using the following columns from the page_data table; id,
filename, title.
I then also have another table:
table: news
++--+-+--+
| id | headline | content | date |
++--+-+--+
| 1 | newHead | contentH| 11.01|
++--+-+--+
| 2 | header | bulding | 12.01|
++--+-+--+
This is much the same as the page_data title. I also have the contents of
the news pages being update into the pagewords and page_searchword tables.
What I need to know is how to look through these at the same time, and get
the new id, headline and content out of the database.
Does anybody have any idea? This does make sense doesn't it? Let me know if
it doesn't thanks.

How about simply backing up the mysql server itself, instead of copying the data over the wire to another machine? If all you do is inserts, and can tolerate having to rebuild the indexes on recovery, you don't even need to take the system down. Just back up the raw database files. If you want a consistent snapshot, you can mysqldump to a local file which you then back up, or create a slave mysqld for backup purposes that you shut down during the backup. That way your main databse is always active. -- Dan Nelson [EMAIL PROTECTED] - 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?

That's a lot of connections per second? Can you use persistent connections? It would save a lot of overhead. Half and half, at the moment .. We had a problem that when we connected to multiple database servers from PHP using persistant connections, it would get confused. By confused I meant 1.) It would 'leak' MySQL connections. Somehow it 'forgot' it had an open connection. 2.) It would pick the wrong server. Each server has specific information on it, in seperate database/tables. The persistant connection code would actually hand back the wrong database handle and the queries would fail. We had to disable persistant connections because of this. Ouch. I hadn't heard about those problems before. It's probably worth testing again, 'cause it will give you a nice boost--especially at that connection rate. Our current my.cnf file: [mysqld] skip-locking set-variable= key_buffer=384M set-variable= max_allowed_packet=1M set-variable= table_cache=400 set-variable= sort_buffer=10M set-variable= record_buffer=10M set-variable= thread_cache=8 You might increase the thread_cache quite a bit. It'll bypass the need to create/destroy threads all the time. It may not give you a big improvement, but it can't hurt. The reason I'm asking is because of the MySQL page on Linux-specific notes. Which basically said you can have lots of threads, providing your key-cache is low. Wonder what that really means... or at least what the rationale behind it is. Have you experimented much with they key_buffer? Any noticeable difference if you double it or cut it in half? I'm trying to get as many threads as I can , and get MySQL to be ram-happy for speed as well. A good plan. ;-) Any changes for this many connections/ram that would be suggested? How are things looking in SHOW STATUS? Any red flags that you've noticed? Any slow queries? Slow queries are actually watched with a fine-tooth comb. I catch anything slow, I first smack the programmer along side the head, then throw Paul's book at them. I attempt to optimize it where possible, or just drop thier table and force them to do it over again. Hahhahahah... Well, that's good to hear, I suppose. The queries themselves seem to be pretty well optimized, I just wanna make sure the config I've got can scale. :) I know the feeling. I'm used to servers with a few hundered connections, with 512 MB of ram .. Not what they want, which is a few thousand, with 2gb of ram.
