Re: Maximum statements per connection problem
John, - Original Message - From: John A. Sullivan III [EMAIL PROTECTED] Newsgroups: mailing.database.mysql Sent: Sunday, June 08, 2003 7:58 AM Subject: Maximum statements per connection problem I am having a nightmare of a time getting a single transaction across multiple tables to work in Borland's Kylix3 with MySQL. It appears that the Borland driver is saying that the MySQL database only supports a single active statement per connection. When I issue an explicit begin transaction, that appears to count as an active statement. When I then try to issue the update (or insert or delete) statement, that appears to be the second active command for the existing connection. Since the Borland driver says the MySQL database is only allowing a single active command per connection, it clones a new connection to handle the update statement. Of course, this new connection knows nothing of the transaction that was begun by the original connection. This renders transaction support impossible with Borland's dbExpress and MySQL (even with InnoDB tables). Is there a way to configure MySQL to report that it will allow multiple active statements per connection? Otherwise, I'm not sure what to do if I want to use transactions (a must for my current project). Thanks. people have been complaining about this on Borland mailing lists for at least a year now. I saw a Borland employee reply there a couple a weeks ago that the MySQL transaction support is coming to dbExpress. Since Borland is marketing their own database Interbase, they have somewhat conflicting interests here. I believe feedback to Borland or their newsgroups can speed things up. -- John A.

However, this self join mysql SELECT a.string, b.string FROM text a, text b WHERE a.string = 'something' and b.string = 'other' and b.string_id = a.string_id+1; is comparatively slow (over a minute to retreive 20 rows), suggesting that indexes are not used. Does anyone know how to optimize this query, or know of another way to select string x, if the next string is y?. An obvious answer would of course be Do you really need a mysql table for this?

Re: passwords in mysql 4.1.0-alpha
Renán, I installed the version 4.1.0-alpha of mysql in Windows XP. At the beginning and in general everything works very well. But I have a problem of incompatibility (I guess). When users are created with passwords, those users cannot be connected. Mysql says: Client don't support the authentication protocol required by server, consider upgrade client. What happen The length of the password hash (in the mysql.user Password column) has changed from 16 (MySQL 4.1.0) to 45 bytes (MySQL 4.1.0). You can still use the old hash length, but this is sort of tricky, and documentation about this is about to be released in the near future. Unfortunately, there will be yet another change regarding the Password column in 4.1.1 that makes documentation of that behaviour a bit more complicated. Anyway, what you describe above is a typical problem that arises when you create a new user (with GRANT) or change an existing user's password (e.g. with SET PASSWORD), and then try to connect as that user with an older client (e.g. mysql from 4.0.13). Trying to connect as that user from a new client should be no problem.

Are you sure it gets this far? Your line above won't compile because of
a missing and a missing ).
$result = mysql_query( SELECT register_id from table_register WHERE
$ssecurity_record = ssecurity_record );

Please, If someone know how to print the record value and Select function in php
send to me.
Read the manual, check return values, etc. If you're running PHP in
apache, then check the error_log and use the error_log() function
instead of print as I use in the code above.
My code above is untested BTW.

Fred.

Re: Replication over SSL

Yes, you could certainly use something like stunnel or an ssh tunnel to forward a port between two machines and do replication over that. Here's a couple of articles that may help: http://www.guydavis.ca/projects/oss/docs/ssh_mysql.jsp http://www.stunnel.org/examples/mysql.html One thing to keep in mind is that when you want to connect to a MySQL server via a non-standard port on your local machine, you need to specify the host to connect to as '127.0.0.1', and not 'localhost'. When using 'localhost', MySQL generally tries to connect using a local Unix socket, and ignores the port you specify.

Load Data Local Infile
OK, tearing my hair out here... I am trying to get a LOAD DATA LOCAL INFILE command to work. It works when I start the MySQL client with --local-infile=1, but never in any other situation. Starting without this option, or submitting the request through PHP or Lasso results in the command isn't supported error. I have tried a million different my.cnf changes, but no luck. Is there any way to tell MySQL to default to allowing LOAD DATA LOCAL INFILE instead of having to specify it in the client login? I'm trying this with both version 3.23.51 and 4.0.12-max. The even odder thing is that I can get it to work fine on another machine running the pre-built 3.23.51 binary from entropy.ch. AND, if I move that build to the 3.23.51 hand-built machine, the error returns. Any ideas GREATLY appreciated.

MYSQL privileges System
Hello: I was wondering if anyone had any advice to a couple questions. 1) Can I add additional columns to the user and db tables of mysql. These would be for administrative purposes only. 2) I'm trying to figure out how the privileges effect the system. I understand what each one does, but haven't found a clear explanation of what the difference is in the db table and the user table. If any one can explain this I would appreciate it. 3) I'm looking to come up with the most secure set of privileges for the user and db tables. I want the users to be able to select, insert, delete, create tables, just the basic functions on their database only. Multiple databases are hosted on the same mysql server. Thank you for your help in these questions. Mike Walth CinoFusion -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Linux install problem
Having run MySQL successfully for a while in a WAMP environment, I'm trying to set up on Linux now (and am a real Linux newbie). I'm using the 4.3.1 version that came as an RPM with SuSE 8.2. The problem is - it doesn't work. Here's where the various elements have installed to: /usr/bin various mysql progs scripts, incl mysql mysqladmin mysql_install_db safe_mysqld etc /usr/sbin mysqld /var/lib/mysql mysql.sock mysql.log linux-bin.001 etc when I run mysql_install_db (in /usr/bin), it creates the 'mysql' dir in var/lib/mysql - so the path to the default database files becomes: /var/lib/mysql/mysql/ From /usr/bin, I run: safe_mysqld --user=mysql and get the message Starting mysqld daemon with databases from /var/lib/mysql but then the daemon shuts down straight away. When I look in the log file, I find: /usr/sbin/mysqld: Can't find file: './mysql/host.frm' (errno: 13) It looks as though the mysql_install_db has put the files in the wrong place. Can anyone give me some advice as to how I sort this out...? Thanks. Steve

1) Any ideas where I might begin to look to find out what is the
problem? Yeah, i'm already considering getting a different host for my
domain since alot of the back end stuff I care about fails to work at
this host -- but their uptime for my web pages is so good.
2) Are there any common configuration/installation/user errors that
contribute to a database not accepting data in the rows?
A. register_globals is turned off, so the the global variables aren't set.
B. The php user does not have 'Insert' privileges.
run SHOW GRANTS FOR [EMAIL PROTECTED]
3) what else might you suggest?
A. Use mysql_query() || die(mysql_error()) construct instead of
guessing at what the error is.
$qry=INSERT INTO foo VALUES('$bar', '$baz', '$bohica');
$res=mysql_query($qry) ||
die ('PError :BR' .mysql_errno .' ' .mysql_error() .'P');
B. add a debug function:
function debug($fl, $ln, $msg='') {
global $debugon;
if ($debugon)) {
printf(\n!-- Debug %s %s:\n, $fl , $ln);
print_r($msg);
echo \n --\n;
}
}
$debugon=1;
$qry=INSERT INTO foo VALUES('$bar', '$baz', '$bohica');
debug(__FILE__, __LINE__, $qry);
Then look at page source to see if the query is what you think it is.

forming foreign keys
Hello Mysql list, I try to create foreign keys in a innodb database. I read through some threats and the manual, and several online resources, but somehow I am missing something. What I try to do is recreate the keys and their functions of the mysql database (privilege database) as a innodb database, including foreign keys to illustrate the relations. The copy of the mysql privilege database is called mysql_privileges_db_inno. The 6 tables structure host, user, db etc. was copied to the innodb database and then modified with ALTER. Now when I try to create a foreign key I get the famous Error 1105 which tells me that I didnt form the request for the foreign key proberly. mysql ALTER TABLE db ADD FOREIGN KEY (User) REFERENCES user (User); ERROR 1005: Can't create table './mysql_privileges_db_inno/#sql-2e8_10.frm' (errno: 150) Could anybody be so kind pointing me to the right direction ?
