mysqldump bug ?
Hello, I'm using mysql-max 3.23.49 binary distribution. I use mysqldump utility to dump tables from my DB. for example: mysqldump --opt -u root -p EFDB users users.sql users.sql file contains: -- -- MySQL dump 8.21 -- -- Host: localhostDatabase: EFDB - -- Server version 3.23.49-max-log -- -- Table structure for table 'users' -- DROP TABLE IF EXISTS users; CREATE TABLE users ( user_id int(10) unsigned NOT NULL auto_increment, name varchar(50) NOT NULL default '', login varchar(20) NOT NULL default '', password varchar(16) NOT NULL default '', email varchar(50) NOT NULL default '', org varchar(128) NOT NULL default '', country char(3) NOT NULL default '', description varchar(128) NOT NULL default '', PRIMARY KEY (user_id) ) TYPE=InnoDB; /*!4 ALTER TABLE users DISABLE KEYS */; . . . INSERT follows. - Now take a look at the line saying: /*!4 ALTER TABLE users DISABLE KEYS */; This means that alter table query will be executed only if MySQL version is 4.00.00 or higher. When i try to use mysql utility to import this dumped file (mysql -u root -p EFDB users.sql) I get the NO SQL QUERY ERROR. This is probably caused by misplaced semicolon ; at the end of the line. In my case, alter table query is ignored because my MySQL version is 3.23.49. Then mysql utility tries to interpret ; as the end of empty SQL query. I think, this semicolon should be placed within the /* */ comments.

COUNT UNIQUE
Given a table with some non-unique column theCol, what is the most efficient way to count the number of different values in theCol? I guess you can use a temporary table as a subselect: CREATE TEMPORARY TABLE tmp SELECT UNIQUE theCol FROM theTable; SELECT COUNT(*) FROM tmp; DROP TABLE tmp; But this seem obscenely inefficient- it's a situation just screaming out for a summary function: SELECT COUNT_UNIQUE(theCol) FROM theTable; Does such a function exist in mySQL?

Many processes in SHOW PROCESSLIST;
Hi, We use mysql 1.23.47 as a database for our PHP based accounting system. We use mysql_pconnect() to get a connection to the DB. This morning we couldn't log in because mysql sent back a 'too many open connection!' (or someting like that) error message. If I use the command SHOW PROCESSLIST than I can see many 'Sleep' processes. If I try to kill some processes by KILL processnumber than newer processes appear in the list. Is there any way to kill all of the hanging processes? And why are so many processes if we use mysql_pconnect() which uses the same connection what the PHP user opened before? Thanks in advance!

In my case I have mySQL access on a Web server where I have NO access to the server-level options. What is my best option of making a backup of the database and tables that I use? if you can use PHP in your site, then you would use phpMyAdmin. Thats a really handy piece of software. You just put it somewhere in your web via ftp like your other web pages and off you go. Preferably you put it in a password protected directory. It has an interface to mysqldump and lets you down- and upload database-dumps. There is just one problem. Some ISPs limit the run time of a PHP action. This might timeout the script before it can finish the dump. Also, what is my best option if I want to move this database and its tables from one ISP to another? mysqldump can include in the dump all commands to rebuild the database at the new ISP. - 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?

Corrupt table content
Hi.
I just saw that one of the tables in a pretty big MySQL-database here
was corrupted. Checked the table with isamchk (yes, it's an
ISD/ISM-database, not MYD/MYI), and found some errors, but corrected
them. But, still the content are pretty .. uh, bad, and the backup isn't
all that recent...
Is there any way to restore this? Does MySQL store some kind of backup
of the tables itself? Or do I just have to dump in a backup ?
Some neat samples of one of the varchar-fields in the table:
\r^?\xa1\xce\xce\x9c^E^X\n\x85:\xe6t\xe2\'k\x

Re: Re: Problem with MySQL, ODBC, MS Access
Sorry I´ve tried it but I didn´t succeed. When writing: update tPruefBesch set fdatetime = fTimestamp, datetime and timestamp wont have the same value. I don´t know why, but there is the same fault. I´ve created a small database to show my problem. That´s my table in MySQL 3.23.41. create table tTest (fTimestamp timestamp(14), fCounter int auto_increment not null, fData1 int, fData2 int, primary key (fCounter)); It´s connected via ODBC 3.51 with Access 2000. I´ve installed Service Pack 2 and MDAC 2.70. Here is the description of my database. When you enter Frm_Test you will see three buttons. Button Test 1 will insert value 1 in column data 1. (When you insert a different value auto_increment will count correctly but it is necessary for my database to have the possibility to insert the same value.) Button Test 2 will insert value 1 in column data 1 und value 5 in column data 2. Button Delete first record will delete the first record. So -. When you first click several times on Test 1 you will consider that auto_increment counts correctly. But when you now click eg 10 times on Delete first record and then click eg 12 times on Test 1 you will see that Counter will show 10 times the same number and then go on counting correctly. The next problem is that when you click on Test 1 until auto_increment counts correctly and then click on Test 2 you will see that value 5 is inserted correctly in data 2, but when you delete 10 records it will 10 times insert the value in another recordset. Note that you will not see that the counter has the same value, because of the requery. You will see the counter is counting correctly but the value is inserted at another place. The problem is that the record pointer will not point to the current record after refresh but to another random record. I hope this will help you understanding my problem.

Re: InnoDB frightens me...
Hi! I'm in the same position as Steve: Considering switching from MyISAM to InnoDB because of the row-level locking capabilities. My application has quite a lot of updates/inserts mixed with selects, and is starting to suffer from the table-locking policy... And like Steve, I'm also scared! :) I've been working quite a lot with MyISAM-tables and I have a good feeling for how it works (backups, data-files, index-files, size of these files, etc) But with InnoDB, I'm - hmmm - confused - that's probably the best word to describe it! The auto-extendible-feature on the todo-list is a great thing! That's one of the big concerns I've had with InnoDB. Another concern is the actual file size - I understand that InnoDB-tables will use a lot more space than the same table in MyISAM... Question is HOW much more (the largest table I currently have is ~2 Gb datafile, 360 Mb indexfile) I'm also confused with how it all works with tablespaces, log-files etc. Is all this common knowledge with transactional databases? If I'm not interested in transactions, do I have to care about all that? And all these limits and parameters! To quote from the InnoDB-documentation: Note that data files must be 2G in some file systems! The combined size of data files must be = 10 MB. The combined size of the log files must be 4G. Hmmm - does any of this put any limitation for my application? (it's a retorical question - I know it depends on my app, but you get the point: It's a lot of new things to learn and consider before switching) And what about backups? Now I'm using mysqldump every night to backup my database - will that be ok for InnoDB too? (I know that it _works_ but what about performance - will it take longer to make a dump with InnoDB-tables? I have to take the website offline while dumping so it's important) I have been looking forward to online-backups, and it is on the todo-list for MySQL 4.1 - will that feature work with InnoDB-tables as well? I noticed that hotbackups is also on the todo-list for InnoDB, but that it will not be free... So... As you can see I'm a bit confused, and I think a lot of people are! It seems to be a whole lot more to learn, more administration, tweaking, etc with InnoDB than with MyISAM. Maybe I'm wrong, but I get that feeling from reading the InnoDB-docs... Maybe some of this confusion and fear could be avoided with a section in the InnoDB documentation that describes InnoDB from a MyISAM-point-of-view :) Explaining how all common things, principles and routines with MyISAM works with InnoDB. I'm sure a lot of people have very good knowledge of MyISAM and comes from the same direction as I do... Thanks for your time! :) /Tobias Steve, I added an item to the TODO list at http://www.innodb.com/todo.html .. May, 2002: Make a data file auto-extendible.

Re: AW: syntax Q
Excuse me for jumping in.
UPDATE table SET a=$a
1. I assume the double quotes in your original message are meant to highlight the
problem statement.
2. As written, you are attempting to set an integer type column to the string literal
consisting of the characters $
and a. MySQL rejects this for either syntax error or type mismatch, whichever comes
first in its parsing.
3. When you place the quotes around $a, PHP replaces it in the SELECT statement with
the value that the variable $a
represents before sending it to MySQL. You'll need to refer to the PHP manual for
more detail.
I trust you had a restful nap.

Betreff: Re: syntax Q
Hello Andreas,
I just encountered the following: let $a be a numeric php
expression,
a
the corresponding integer field in a table. When I say: UPDATE
table
SET a=$a it denies the update. When I say: Update table SET
a='$a'
it
performs the update. Uhm, now I am wondering. Isn't 'something'
supposed
to be a string?
Agreed.
What does the SQL CREATE statement look like?
What does PHP's assignment of value to $a (and relevant statements
leading up to it) look like?
Are you sure (the PC thinks) they are both integers?
Created with phpmyadmin, column type integer(10). Value to be
inserted
comes from a method=post script at no point treated other as a
numeric...
=uh-oh, my theory is looking shaky!?
However such conclusion (numeric) may not be the case. Try running the
'form' and inserting a specific integer value, eg 7.
Put a debug routine like this into the PHP after the POST is processed
and before the MySQL call:
echo Value of a appears to be $a~;
if ( $a == 7 ) { echo PHP says it is seven; }
else { echo PHP says it is not seven; }
if ( $a === 7 ) { echo PHP says it is integer seven ; }
else { echo PHP says it is not integer seven ; }
echo BR;
(code not syntax checked)
Please advise,

RE: text data cut off at space
You have to enclose the data in quotes or it cuts off at the first space.
Example:
$resultID = mysql_query(INSERT INTO data_table (name, address) VALUES
($name, $address),$connect);
This will cut off the text at the first space in the text field
This is the method that worked for me:
$resultID = mysql_query(INSERT INTO data_table (name, address) VALUES
('$name', '$address'),$connect); //notice the quotes
I am assuming that the $name and $address are coming from a form. Hope this
helps

Re: InnoDB frightens me...
Hi Heikki, I don't know if this has been requested, but what about a tool to 'pre-create' dataspace? This tool would allow someone to create a new dataspace, then a quick restart (After adding the name of the space to 'my.cnf') and the new dataspace is available! Maybe just extract the pieces from MySQL code and make it a separate tool? I know I don't want to have a server shutdown while it creates 10GB of Dataspace! Of course autoextending is one answer. One could just create a small dataspace and let it autoextend.

Meaning, that if I put , This Blob's for you! in the column, the value of MYSQL_FIELDS.length = 65535 (max of BLOB type) and MYSQL_FIELDS = 21. When I update a few rows and put, That's OK man, but you still can't have my BLOB! in a few columns, the values for the length of the fields are returned funny, or at least, I don't understand why they are returning they way they are. Meaning the value of the new column length are all set to MYSQL_FIELDS.length = 65535 (again, max of BLOB type) and MYSQL_FIELDS = 49. EVEN ON THE UNCHANGED ROWS! Yuk! A little experimentation showed that if I select on only unchanged rows, the length is returned as 21. But, if the result set has one of the changed rows in it, the length of all blob fields is returned as 49, when (at least to me) it should be 21 or 49. In other words, it returns as the BLOB max_length value the value of the longest blob in the result set, NOT the max_length of each row. I inserted (and updated) some records in the table with BLOB contents It's all about the BLOB and I see the same result. It returns not the length of the BLOB for the row, but the length of the longest BLOB field in the result set. We are running MySQL 3.23.46-Max on RedHat 7.2 Question: 1) How do I get the actual length of the BLOB column in the row, without storing a separate column to maintain BLOB length manually?

Dynamic SQL
Using UltraDev 4 with Phakt 1.2.1, linking to a MySQL server 3.22.23
I want to develop a SQL SELECT query where I can vary what customers are
listed depending on the value of various form fields.
For example if the check box surname_all is ticked then all customers are
displayed if not then it displays all customers where the surname lies
between surname_from to surname_to.
I couldn't find an appropriate way of handling this in MySQL directly so my
aim was to determine the SQL portion outside the query and then append it to
the query:
if ($surname_all == -1){
$surname_query = WHERE surname between $surname_from and $surname_to;
} else {
$surname_query = ;
}
NB - If $surname_all = -1 then it has been ticked.
And then I would declare my SQL statement as
SELECT * from customers.$surname_query
UltraDev doesn't like this and so I would appreciate any help in either a
better way to code it in UltraDev or a SQL statement that would achieve the
same aim.
Thanks for your help

Replication code from 3.23.25-beta to today.
Hello, I'm looking to port a MySQL replication set that runs 3.23.25-beta to a later version of MySQL. I understand that the format for the binary log changed from .25 to .26 and again at 4. It appears, from looking at the code for 4, that it looks at the version of the replication master and if it's a 3.x master it will use the appropriate format. I've yet to find the correct logfile structure but would like to work with the version 4 code to make it check for the really-old version of the binary log and work with it. Therefore, can someone point me to the logfile structures? Am I attempting the impossible by trying to get version 4 to read a binary log of 3.23.25?

Re: LOAD DATA INFILE and how to ignore garbage lines at end ofload file?

Using UltraDev 4 with Phakt 1.2.1, linking to a MySQL server 3.22.23
I want to develop a SQL SELECT query where I can vary what customers are
listed depending on the value of various form fields.
For example if the check box surname_all is ticked then all customers are
displayed if not then it displays all customers where the surname lies
between surname_from to surname_to.
I couldn't find an appropriate way of handling this in MySQL directly so my
aim was to determine the SQL portion outside the query and then append it to
the query:
if ($surname_all == -1){
$surname_query = WHERE surname between $surname_from and $surname_to;
} else {
$surname_query = ;
}
NB - If $surname_all = -1 then it has been ticked.
And then I would declare my SQL statement as
SELECT * from customers.$surname_query
UltraDev doesn't like this and so I would appreciate any help in either a
better way to code it in UltraDev or a SQL statement that would achieve the
same aim.

RE: Dynamic SQL
Thanks for that.
It's actually more the UltraDev/Phakt thing I'm having problems with. I just
wondered how you would set the SQL statement in such a way that UltraDev
wouldn't complain - it doesn't like SELECT * from customers.$surname_query.
Do you know of a good way of handling conditional statements in MySQL?

extra max() function possibly very useful?
Hi,
What would the plausability of a function like this being implemented in the
future.
create table mytable (id int, val char(255), hits int);
insert some data...
select max(5,hits) from mytable group by id;
This would allow selecting of the top 5 rows for each id according to the
hit column.
Without this function it means the code must be written manually as,
foreach(id) {
select * from mytable where id='$id' order by hits desc limit 5
}
which is obviously quite inefficient where the domain of id becomes large.
Any input from the developers about the possibility of this functionality
would be much appreciated.
Richard

Re: extra max() function possibly very useful?
Because that wouldn't give the correct results.
I want the top 5 rows for EACH id.
A short example would be,
mytable:
IdValHits
1 a 10
1 b 15
1 c 17
2 q 200
2 r 205
2 s 101
2 t 50
3 zz 10
3 yy 20
3 xx 30
3 ww 40
3 uu 50
select max(2,hits) from mytable
Id
1 b 15
1 c 17
2 q 200
2 r 205
3 ww 40
3 uu 50
This is the top two rows for EACH id...
without this functionality i have to do
select distinct cid from mytable;
foreach(cid) {
select * from mytable where cid='$cid' order by hits desc limit 2;
}
Which means the table is reread over and over. With this extra function we
could reduce the reads to at best once.

Re: LOAD DATA INFILE and how to ignore garbage lines at end of load file?
Is this a true export? Because I've never had garbage lines in my files.

The problem is Oracle puts garbage lines at the end of it's output files. As you've noted, the problem is Oracle. If you're using Unix, you could use tail to see how many of these lines there are and wc to count the total number of lines in the file. With that information, you can construct the proper value of n and use head -n to get only the initial part of the file that contains the non-garbage lines. Or you could reverse the order of the lines in the file (expensive?) and then use IGNORE n LINES in your LOAD DATA statement to ignore the first n lines. Better if you can get Oracle just to suppress these lines in the first place. Perhaps someone else will have a suggestion how to do that. Lines like 300 rows selected and input truncated to 9 chars as well as empty lines. When MySQL loads these files, I'm getting rows inserted for the empty lines at the end of these files. Can I get MySQL to ignore empty lines at the end of these files? or if anyone has Oracle experience can I get it to suppress the output of these line?

There has been talk of this before.

Deleting duplicate records
Hi to all, I'm new using mysql. I'm trying to load data from a text file to one of my table. This text file contains duplicate records. My question is how do you tell mysql to delete duplicate records and load just the ones that are not duplicate? I already tried the REPLACE and IGNORE key words but is I dont get the result that I want. Any idea Thanks in advanced.

That means there will be more open connections to the database server. If you have a sufficient number of Apache (or whatever) children, you can easily over-run MySQL.

Can't restart MySQL after innodb table filled up
I'm having problems restarting a MySQL server after a certain table reached maximum capacity. I managed to dump my entire database to a flat file before I restarted the server however when I tried to re-import my data the operation failed. My database size set to 500M in the innodb section of my my.cnf file. I'm running RH 7.2, kernel 2.4.19pre1 with 512M of RAM and have rebooted the server without any change in results. I've also upgraded MySQL-Max from 3.23.48 to 3.23.49a using the RPMS on mysql.com. I've tried removing all the innodb files within my database directory and MySQL seems to build the new 500M file properly but then crashes with the following message in the mysql.log: 020304 11:33:01 mysqld started 020304 11:33:02 InnoDB: Database was not shut down normally.

Web server performance
I am currently implementing a database-ran webserver dll: Info: Ms Visual C++ MySQL ++ 1.7.1 MySQL-nt 3.23.47 MyISAM db. 3or 4 Queries in the application Biggest Query: 66,000 records using LIKE something% Question: I am currently using a connection every time I query, but since this is a static dll, can I somehow keep a connection open for all the queries? I have tried just opening a connection before(one connection for the app, all threads use it), but sooner or later, the queries start causing exceptions and then returning no error until the dll faults because the connection closes. Is there a way to tell the database that the connection needs to handle multiple queries in a parrallel manner? Any other speed tweaks if I have to open a different connection for each query?

RE: Slient install - Win32 Mysql
I have the same problem (silent install). In details: I run setup.exe with command line options -r to create response file needed for silent installation in InstallShield. By default it is created in the windows directory with name setup.iss. Then I move this setup.iss to the same folder as setup.exe and try to run setup.exe -s to perform the silent setup, but it fails. The log file contains: [InstallShield Silent] Version=v4.90.000 File=Log File [ResponseResult] ResultCode=-3 According to IS documentation: -3 Required data not found in the Setup.iss file. Even if I set verbose this is all I have. I didn't find the source for the InstallShield project in the source distribution (I searched for *.ipr, *.rul). What a pity! With the IS project source in hand it would be a piece of cake to handle this situation. BTW this silent setup thing is working with another software (I tryed it with J2RE 1.4.0 - I had to collect the exracted stuff from the temp directory during installation but then it worked all right). Maybe there's a bug in the InstallShield version used (it is an old 5.x version). Maybe there's a bug in the IS project for MySql. Maybe I'm doing something wrong. But I guess it makes *no sense* that everyone writes his/her own silent setup for MySql when there is an official one already. Thanks, Attila -Original Message- From: Gerald R.

Re: Can't restart MySQL after innodb table filled up
Erik, this is probably not a bug. Your log files probably are not the ones which belong together with the current data file(s). When you start the database it tries to use the obsolete log files in recovery. From the manual: If something goes wrong in an InnoDB database creation, you should delete all files created by InnoDB. This means all data files, all log files, the small archived log file, and in the case you already did create some InnoDB tables, delete also the corresponding .frm files for these tables from the MySQL database directories. Then you can try the InnoDB database creation again. It is best to start the MySQL server from a command prompt so that you see what is happening.

merge problems under 3.23.47?
Short version: I have 2 identical tables and I created a merge table to query them all at once (v 3.23.47). I can select on only two of the four keys in the table. Attempts to select data from the merge table WHERE column = xxx always return 0 rows for the other two keys. Queries using WHERE column LIKE xxx do work, but of course they're very, very slow. The problem seems to arise when the total line count of the two tables reaches 20. Long version: I have 2 tables that look like this (it's dhcp lease polling information): CREATE TABLE t1 ( ip_address_id INT UNSIGNED, cm_mac_id MEDIUMINT UNSIGNED, cpe_mac_id MEDIUMINT UNSIGNED, hostname_id INT UNSIGNED, starts DATETIME, endsDATETIME, KEY (ip_address_id), KEY (cm_mac_id), KEY (cpe_mac_id), UNIQUE KEY (ip_address_id, starts) ) TYPE=MyISAM RAID_TYPE=STRIPED RAID_CHUNKS=2 RAID_CHUNKSIZE=1024; I'm merging them together like this: CREATE TABLE t_merge ( ip_address_id INT UNSIGNED, cm_mac_id MEDIUMINT UNSIGNED, cpe_mac_id MEDIUMINT UNSIGNED, hostname_id INT UNSIGNED, starts DATETIME, endsDATETIME, KEY (ip_address_id), KEY (cm_mac_id), KEY (cpe_mac_id), KEY (ip_address_id, starts) ) TYPE=MERGE UNION=(t1, t2); These queries work fine: SELECT * FROM t_merge WHERE ip_address_id = 1234; SELECT * FROM t_merge WHERE ip_address_id = 1234 AND starts = '2002-03-02 00:59:05'; SELECT * FROM t_merge WHERE ip_address_id = 1234 AND cm_mac_id = 5678; SELECT * FROM t_merge WHERE ip_address_id = 1234 AND cpe_mac_id = 5678; DELETE FROM t_merge WHERE cm_mac_id = 5678; DELETE FROM t_merge WHERE cpe_mac_id = 5678; These queries return 0 rows: SELECT * FROM t_merge WHERE cm_mac_id = 5678; SELECT * FROM t_merge WHERE cpe_mac_id = 5678; These queries work correctly, but of course very slowly: SELECT * FROM t_merge WHERE cm_mac_id LIKE 1234; SELECT * FROM t_merge WHERE cpe_mac_id LIKE 1234; In testing, the problem only arises when the total line count of the two mapped tables reaches 20.

difference between two times
Hello,
I am trying to get an accurate (nearest 15 minutes would be
fine) difference between two times that I have in my database. They are
both of type time, and are in the format 00:00:00.
For example, if I want the difference between 09:20:00 and 10:43:00, I
would like it to give me 01:23:00 as the answer, but all I have been able
to get it to do is give me one. It is rounding to the nearest hour.
I found this query which seems like it would work, but gives me a NULL
result set:
SELECT DATE_SUB('11:48:02', INTERVAL '10:37:37' HOUR_SECOND);
I am trying to do all of this from PHP, so if you happen to know of a way
to make it do the subtraction in PHP without losing all accuracy, please
let me know.
Thanks for any help you can offer.

Deleting rows from logging db efficiently
Using MySQL 3.23.40 App is logging db with 130 clients to a central MySQL db with 2 million events per day. Aged events of over 7 days are no longer required. The central table is myisam type with fixed size (datetime, enum and foreign keys only). Selects are done infrequently while inserts are done throughout the day. What is the fastest delete possible and still keep table optimized? Here are two ways that were developed. Either algorithm is done once a day when server activity is at a minimum. The first technique is in the documentation, the second technique is twice as fast. Delete rows and optimize DELETE FROM table WHERE etime2002-02-25; OPTIMIZE TABLE table; The time to delete 2 million rows is 24 minutes. The time to optimize is 18 minutes. Total time is 42 minutes. Transfer only newest data to no-index temporary table LOCK TABLES table t READ; INSERT INTO table_tmp SELECT * FROM table WHERE etime2002-02-25; TRUNCATE TABLE table; UNLOCK TABLES; INSERT INTO table SELECT * FROM table_tmp; The time to insert 10 million rows into temporary table is 3 minutes. The time to truncate table is 5 seconds. The time to insert from temporary table back to primary table is 18 minutes. Total time is 21 minutes. Does anyone know of a different approach of deleting rows while keeping the table optimized? Would welcome any comments. David PS1 Optimized table is defined as no deletes to table without a subsequent optimize. If deletes and inserts are done simultaneously, query times go up drastically. This slowdown is documented. PS2 Hardware is a 4 cpu Solaris with key_buffer=1024M thread_concurrency=8. Only other db in mysql is used infrequently. --- David E Lopez email: [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?

Can't create a new thread
Hi! One of the users on a webserver I'm running are having some serious problems connecting to the MySQL server. He get's the following error: mysql error: Can't create a new thread (errno 11). If you are not out of available memory, you can consult the manual for a possible OS-dependent bug. I've been reading the MySQL manual about some problems with old versions of glibc and RedHat 5.1, but this is a Debian testing-server running MySQL version 3.23.47, and glibc version 2.2.4.

Re: difference between two times
lastout and firstin contain times such as 13:28:01 and 13:27:54.
If I use the query you gave me from within phpMyAdmin, the result I get is
7 seconds, exactly what it should be...but I do not know how to use PHP to
get the correct result, it is giving me 23. I am accustomed to using
mysql_result to get results but it needs to know the result variable
($result), the row (should be 0?), and then the last one is usually the
field name, but in this case I don't think I have one because I'm asking
it to select a math operation, so where does the result go, and how do I
get it with PHP? Thanks.

Paul,
You're awesome...thank you. One more question pertaining to this...
I'm accustomed to selecting a variable and using something like this:
$firstin = mysql_result($result,$row,firstin);
to set my variable.
What do I want to do here to get the right result into my variable?
$query2 = SELECT SEC_TO_TIME(TIME_TO_SEC('$lastout') -
TIME_TO_SEC('$firstin'));
$result2 = mysql_db_query($database, $query, $connection) or die
(Error in query: $query. . mysql_error());
This isn't working, I get 23:
$total = mysql_result($result2,0);
I guess it depends on what the values of $firstin and $lastout are, and
how you're displaying the value of $total. It's hard to say anything
without seeing more of the code.
Thanks again!

For two times t1 and t2, compute the difference in seconds like this:
SELECT TIME_TO_SEC(t2) - TIME_TO_SEC(t1)
If you want the result as a time value, pass it to SEC_TO_TIME():
SELECT SEC_TO_TIME(TIME_TO_SEC(t2) - TIME_TO_SEC(t1))
