Re: sizes
Mattias,

ENUM has a storage requirement of 1 or 2 bytes. If you have up to 256
ENUM values to choose from, you need 1 byte, if you have more, it will
take 2 bytes. TINYINT will always need 1 byte.

Can't set timeout on MyODBC/MySQL from an ADO/ASP program on Windows XP?
Hi, I've tried without success to set a timeout for SQL queries on a MySQL server (version 4.0.12 - so far the latest production release) running on a Windows XP SP1 box. The calling program is a Web site developed in ASP (going through ADO to access MyODBC...). I tried many different methods but there is no way I can STOP a SQL query that takes too long to execute (like... more than 5 minutes) and RAISE AN ERROR to the calling application (in that case an ASP page).

Autoincrement/last_insert_id race safe?
A programmer just asked me about a possible race condition, and I didn't know what to answer: If I insert a line using autoincrement, then ask for last_insert_id() am I guaranteed to get the same ID I just inserted?

RE: mysqladmin -u root -h myhost password 'new-password' fails
You guys probably need to start mysql with the --skip-grant option and fix the allow tables... See the mysql.com website or google.com for lost password mysql Thanks for the tip about how to proceed. Just so we don't lose track here, the point of the bug we're reporting is that mysql_install_db is telling us to do something that doesn't work (and, even worse, leaves the [EMAIL PROTECTED] user without a password). So either mysql_install_db should be changed to say the right thing, or the command should be made to work :). I do not know enough to even guess what the underlying problem might be.

Bug Report, timestamp columns
Hi Mysql, This is a bug report. There are two cases, because the bug is quite old, I detected it the first time a year ago on a 3.23.44 with MyISAM, but I thought it would be fixed soon, sorry. This bug happens in 4.0.8 too with MyISAM tables. Test Case 1 --- Operating System: Linux Intel, SuSE 6.3 (Kernel 2.2.13) Processor : ADM K6-2 400 System RAM : 128M Disk Subsystem : SCSI-2 (dpt) FIle Sytem handler : ext2 MySQL version: mysql-max-3.23.49a-linux-gnu-i686 Table Handler: Derkeley DB. Symptom : Two colums are updated insted of one. ---the script starts here create database prueba; use prueba; create table pr (a int, b timestamp, c timestamp, d timestamp, e int) type=bdb; insert into pr values (0, now(), now(), now(), 1); select * from pr; # # Insert a delay here !!! # update pr set c=now(); select * from pr; the script ends here- the output from `mysql -t pr1.sqlsal' client is: +--++++--+ | a| b | c | d | e| +--++++--+ |0 | 20030324145209 | 20030324145209 | 20030324145209 |1 | +--++++--+ +--++++--+ | a| b | c | d | e| +--++++--+ |0 | 20030324145304 | 2003010110 | 20030324145209 |1 | +--++++--+ As you can see the colum `b' is updated, too.

Strange Query
Don't know if this has already come through to everyone, if so I apologize. Ok, here's the deal Table1 is a master list holding ID numbers, and related information sent by clients Table2 is a queue that utilizes Table1.ID numbers, and updates other information on the current state of a job associated with these ID numbers within Table2. This table is used only as a queue, so the Table1.ID numbers come and go as jobs complete. There can be multiple instances, or 0 instances of Table1.ID on Table2. Table3 is a log that contains even more information concerning the Table1.ID numbers, and associated processing information from Table2, and information of further processing, shipping status, tracking numbers, etc. There can be multiple instances, or 0 instances of the Table1.ID number on Table3. So, what I am trying to do is this: Table1 holds this info(simplified): MasterID(Unique) int NumberRequested int Table2 holds this info(simplified): MasterID int OrderID(Unique) int Table3 holds this info(simplified): MasterID int OrderID(Unique) int JobState bool What I need to extract, within a single statement, is this: For each MasterID on Table1 What is the NumberRequested Does the MasterID exist on Table2, if so, how many times? (QUEUED) Does the MasterID exist on Table3, and if so, How many times with JobState TRUE (GOOD) How many times with JobState FALSE (BAD) If the NumberRequested is greater than QUEUED+GOOD, then return a 1 as (UHOH) So, looking for a return like: MASTERIDNUMBERREQUESTED QUEUED GOOD BAD UHOH 1 105 4 1 1 2 1010 0 0 0 3 108 2 1 0 4 106 0 4 1 5 100 100 0 6 100 5 5 1 This is what I tried: SELECT Table1.MasterID AS MasterID, Table1.numberofcopies AS numberrequested, SUM(CASE WHEN TABLE3.jobstate=0 AND TABLE3.MasterID=Table1.MasterID THEN 1 END) AS good, SUM(CASE WHEN Table3.jobstate=1 AND Table3.MasterID=Table1.MasterID THEN 1 END) AS bad, SUM(CASE WHEN Table2.MasterID=Table1.MasterID THEN 1 END) AS queued, (CASE WHEN numberrequested queued+good THEN 1 ELSE 0 END) AS uhoh FROM Table1, Table2, Table3 GROUP BY Table1.MasterID; Help please?

Transaction support
Hello, I experiencing a problem I hope someone here can help with: I have several C-coded clients running and performing inserts and updates on a database. I would like to make sure that the -entire- client session is atomic. i.e. if a client dies in the middle of the computation (not uncommon) then all of the updates are rolled back. I take it I can do that by using InnoDB tables and transactions the problems: - the number of updates and inserts per client is large ~ 10,000 or so inserts/updates on many tables. I need ALL of them to be one single atomic operation. is there any limit on the size of a transaction. any way to increase such a limit? - if the client dies in the middle of the computation it obviously won't be able to issue an explicit rollback. what happens in this instance. is possible to set things up so that an automatic rollback takes place. - this might be tricky. but during most inserts my C program retrieves row ids (using mysql_insert_id() function. this id is then used in subsequent inserts. would that still work with transactions. i.e. without committing an insert to a table, what would mysql_insert_id return? - would performance with such large transactions be substantially degraded? this is rather important issue for me. I'd really appreciate any help in this regard. many thanks in advance Murad -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: sum() using group, and duplicates problems...
The DISTINCT is almost usless when done on a GROUP BY clause. Also DISTINCT operates on the entire row and not just on the field. ie It will give you DISTINCT measurement, sum(val), pcfver, hour, release. And not just DISTINCT measurement results. Serge.

MySQL 4.0 Questions....
Hi, I am using MySQL 4.0 (with Embedded Server) on a Mac OS X (Darwin) machine. I am using the C API of MySQL in my programs. I have a few questions regarding this. 1) When I compile my programs with the g++ 3.1 compiler, i get the following warnings: ld: warning multiple definitions of symbol _qsort /usr/local/lib/mysql//libmysqld.a(libmysys_mf_qsort.o) definition of _qsort in section (__TEXT,__text) /usr/lib/libSystem.dylib(qsort.So) definition of _qsort ld: warning multiple definitions of symbol _regcomp /usr/local/lib/mysql//libmysqld.a(libregex_regcomp.o) definition of _regcomp in section (__TEXT,__text) /usr/lib/libSystem.dylib(regcomp.So) definition of _regcomp I believe the files in the directory /usr/lib/ are not mysql files i don't want to delete them as well... Is there any solution for this??? I am not sure whether these warnings will cause any serious problems... 2) When I am using an Embedded Server, will i be able to connect to a normal mysql server running on a different machine by specifying the appropriate arguments in the mysql_real_connect() function? 3) I also have another question. The maximum size of a table in MySQL is determined by the type of the machine. If the size of a table goes beyond this limit, what will happen? (will MySQL take care of creating another table and dumping the excess data into that or the sytem will give an error message) I would really appreciate if anyone can help me on these questions... thanks, Babu... -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

MySQL 4.0 Questions...
Hi, I am using MySQL 4.0 (with Embedded Server) on a Mac OS X (Darwin) machine. I am using the C API of MySQL in my programs. I have a few questions regarding this. 1) When I compile my programs with the g++ 3.1 compiler, i get the following warnings: ld: warning multiple definitions of symbol _qsort /usr/local/lib/mysql//libmysqld.a(libmysys_mf_qsort.o) definition of _qsort in section (__TEXT,__text) /usr/lib/libSystem.dylib(qsort.So) definition of _qsort ld: warning multiple definitions of symbol _regcomp /usr/local/lib/mysql//libmysqld.a(libregex_regcomp.o) definition of _regcomp in section (__TEXT,__text) /usr/lib/libSystem.dylib(regcomp.So) definition of _regcomp I believe the files in the directory /usr/lib/ are not mysql files i don't want to delete them as well... Is there any solution for this??? I am not sure whether these warnings will cause any serious problems... 2) When I am using an Embedded Server, will i be able to connect to a normal mysql server running on a different machine by specifying the appropriate arguments in the mysql_real_connect() function? 3) I also have another question. The maximum size of a table in MySQL is determined by the type of the machine. If the size of a table goes beyond this limit, what will happen? (will MySQL take care of creating another table and dumping the excess data into that or the sytem will give an error message) I would really appreciate if anyone can help me on these questions... thanks, Babu... -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Data entered in PHP not appearing in mySQL
Do a print $testField; first. I think what might be happing is that you have register
globals turned off (as you should it's a security problem).
Try:
$sql = INSERT INTO testTable values ('', '${_REQUEST['testField']}');
and see if that solves your problem.

Re: Problem starting 4.0.12 server
Yes, probably. I've never used a mysql rpm, so I don't know how they're packaged. /var/lib/mysql is an odd place to stick that socket though. I've always seen it in /tmp or someplace similar (and world readable). errno = 13 -- Permission denied Make sure that directory is owned by mysql, ie $ chown mysql database dir $ chmod 700 database dir It seems rather odd that an rpm would stick anything in /ul/mysql. Did you move the stuff there and create a symbolic link to it? That won't necessarily perserve permissions and ownership. If you're having that much trouble with the rpm, a source build may or may not be what you're looking for. I'd go that route, but any of my co-workers can attest to the fact that I'm an obsessive compiler. -jeff On Wed, 2003-03-26 at 15:49, Saul wrote: From: Jeff Kilpatrick [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Organization: Date: 25 Mar 2003 21:08:56 -0600 Does the mysql user have permission to write to /var/lib/mysql? -jeff Well, it didn't.

Well, I could... except that the documentation, as far as I'm concerned, leaves a lot to be desired. -jeff On Wed, 2003-03-26 at 15:49, Saul wrote: From: Jeff Kilpatrick [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Organization: Date: 25 Mar 2003 21:08:56 -0600 Does the mysql user have permission to write to /var/lib/mysql? -jeff Well, it didn't.

RE: Beginner question - Preventing Duplicate Entries
Add a UNIQUE INDEX to the table you are inserting to. You will then get an error if you try to insert a second time with the same values. Alternativly you could use perform a select and then an insert within the same transaction, determining whether something exists in the db before inserting. This of course would require transactions supported by InnoDB tables and not supported by MyISAM. ~Wynne -Original Message- From: Wileynet [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 26, 2003 2:04 PM To: 'mysql users' Subject: Beginner question - Preventing Duplicate Entries Is there a sql statement that would not allow the same entry twice.

It seems the only way to edit the orderNum is, delete the children (purchaseOrder_items) or move to a tem table, then edit the parent orderNum and add back the children with the new orderNum, This is to many transactions. Is there any better way to edit foreign key values Of course I can switch to the a upper mysql version(4.0.8), if that is the only solution, which one is recommendable??

RE: granting privileges using wildcards
That would grant the user select on everything in every database no matter what host they are coming from. He wants to only grant on specific tables, and did not mention anything about allowing from all hosts. To answer the original question, I have tried a lot of different ways, but the only solution I have found is granting on the entire database or specifing each table in the tables_priv table. I go with the second option because although it is more work I like only allowing as much access as needed. The wild cards just don't seem to work in this instance.

Controlling replication of GRANT/REVOKE queries?
My replication was going fine until the slave attempted to execute a REVOKE query referring to a user that didn't exist on the slave. That caused an error and brought replication to a halt. I'm using replicate-wild-do-table to set the databases I want to replicate. If I'm not replicating the mysql database, it seems that the slave shouldn't be attempting to execute GRANT and REVOKE queries it receives from the master. Is there no way to prevent this?

Re: Transaction State handling in Mysql.
Hello Ramanan- First off, make sure you create tables of type InnoDB, Berkeley, or Gemini. [My]ISAM tables don't do transactions. The simplest way to do a transaction is mysql BEGIN; mysql # successful edit mysql COMMIT; or mysql BEGIN; mysql # failed edit, or dropped connection implies mysql ROLLBACK; To create non-isam tables, append TYPE = InnoDB or similar to create statements. You can convert current tables using ALTER TABLE, but each type must be compiled in and setup in my.cnf One caveat: be sure all the tables affected are of one of the above types or you won't get a full rollback, leaving you in a crazy state with some badly updated tables (right guys? I think I read that in the docs a couple years ago). -jeff On Wed, 2003-03-26 at 22:33, [EMAIL PROTECTED] wrote: Hi all, I want to execute a set of Insert,Update and Delete if any one of the statement fails then I need to rollback all the statements.

Re: MYSQL Database - followup
Your spelling of PRIVILEGES is also spelled wrong =) specifying GRANT ALL PRIVILEGES on *.* to a user will make that user a member of the superuser group such as mysql, just without the GRANT OPTIONS, meaning that user's login wouldn't be able to GRANT other users. if you want to specify the database just do a mydb.* meaning all tables within the mydb database. then, mysqlflush privileges; i hope that helps.

RE: Passing data between the web to an Intranet
Steve, Hopefully I am correctly interpreting what you want to do. While I don't have anything of this kind in operation, I did come close to implementing it as a solution to a problem that I eventually found another way around. My proposed solution was to have a script set up on the web server that, when browsed to, would output a list of records from a MySQL database. This would be a 'hidden' script not linked to by any other pages so that a casual browser of the site would not accidentally come across it. A script on the internal intranet could then be cron'd to browse to that page, slurp up the output of the remote page and store it in MySQL locally. The local script could be triggered manually each time an update is done, or there could be, perhaps, a database entry on the remote server that is set to '1' whenever data is changed. The '0'/'1' is output first and the local script could then test that first and either proceed with data capture or break the connection if nothing has changed. Hope this is useful!
