Definition of mysql_server_init
Hi All I am trying to port my MySQL code on HP-UX, and am anuable to link my code as I am getting the standard functions like mysql_query(), mysql_store_result() etc as undefined. I am currently linking my code with libmysqlclient_r.a. Do I need any other library to be linked as well?? -- Bye for now, Nishant God Gave Me Nothing I Wanted, He Gave Me Everything I Needed !
Query not using indexes?
Here is a query I'm trying to run. It doesn't look like it is overly complex and, granted, it's joining on a few tables, I wouldn't imagine it would take 6.5s to execute. SELECT TRIM( users.username ) AS username, TRIM( games.game_name ) AS game_name, CASE WHEN 0 != UNIX_TIMESTAMP( MAX( collections.modified )) THEN TRIM( MAX( collections.modified )) ELSE TRIM( MAX( collections.created )) END AS modified, TRIM( users.hide_inventory ) AS hide_inventory FROM collections INNER JOIN users ON users.id = collections.user_id INNER JOIN game_pieces ON game_pieces.id = collections.game_piece_id INNER JOIN games_sets ON games_sets.id = game_pieces.games_set_id INNER JOIN games ON games.id = games_sets.game_id GROUP BY users.username, games.game_name ORDER BY users.username; 167 rows in set (6.49 sec) Table collections has 76,328 rows Table users has 291 rows Table game_pieces has 5,491 rows Table games_sets has 29 rows Table games has 3 rows Table games has a FK for games_sets which has a FK for game_pieces.

Make sure that all joined fields are of identical types, otherwise the query executor must cast each and every join value, which may be affecting the query time...

Copying DB to new structure
We have a moderately sized database, more than 5GB in size, several million rows and 70 tables. We're running MySQL 5.22 and the database uses innodb throughout with multiple foreign keys in use. During development the structure of several tables has been changed many times, such that we now have a number of rendundent columns. We've created a new, empty database with our proposed new structure and I'm now looking for the most efficient way to get our existing data into this new structure, dropping any data in columns that no longer exist. Can anyone propose a sensible way to go about this? Because we're using innodb, dropping columns one at a time takes an age as every index is rebuilt. Just laoding the database from a mysqldump file takes about five hours so I'm pretty sure we'll want to load data from our old database into the new db with the new structure - if anyone can recommend a strategy to do that, or suggest an alternative, I'd be most appreciative!

account that can only do backup
Hi, I want to create a MySQL user account that can only do database backup but nothing else. What privileges does such an account need?

MySQL 5.0.27: character problem
Hello, I'm using MySQL version 5.0.27 under Windows XP professional. I have a text file with some SQL commands (I create a few tables and insert some rows into them). I noticed that all columns where I tried to insert a swedish character, that character got corrupted. But it works if I type the same explicitly in mysql monitor. What do I need to do so I can use command files and still have proper handling of swedish characters? - Eric -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
definition of Created_tmp_files in show status
According to the mysql reference manual, the definition of this field is: How many temporary files mysqld has created. Can someone elaborate on this? What causes mysql to create a temporary file? I see something indicating it may be associated with replication. In our environment (which has replication) we see counts for this variable in the tens of thousands.

Re: Replication Problem? - SOLVED
It turns out that I have a binlog-ignore-db option configured for
another database. If you have even one of these you must make all
updates in the default database if you want them to be replicated. This
is a change in behavior from 4.0 to 4.1. We upgraded from 4.0 to 4.1 to
5.0 the same day which explains why we did not see this behavior sooner.
I removed the option from the config file and just used
replicate-ignore-db instead and all is right in the world again. Hope
this helps someone else down the road. Thanks for all of your helpful
information and suggestions.

Tell the slave to restrict replication to statements where the default
database (that is, the one selected by USE) is db_name. To specify more
than one database, use this option multiple times, once for each
database. Note that this does not replicate cross-database statements
such as UPDATE some_db.some_table SET foo='bar' while having selected a
different database or no database.
An example of what does not work as you might expect: If the slave is
started with --replicate-do-db=sales and you issue the following

USE prices;
UPDATE sales.january SET amount=amount+1000;
The main reason for this just check the default database behavior is
that it is difficult from the statement alone to know whether it should
be replicated (for example, if you are using multiple-table DELETE
statements or multiple-table UPDATE statements that act across multiple
databases). It is also faster to check only the default database rather
than all databases if there is no need.
If you need cross-database updates to work, use

You can run a select * from mytable and see whether any columns are in order; that's about it. Note that if records were inserted/deleted since the sort, no column may be completely in order. And a related question: how to determine which is the index #2? I guess if I look at the order of indexes in the 'SHOW CREATE TABLE name' report that will do it. Is that the right way? Is there more official way?

Unfortunately, MySQL refuses connections from external IP's that aren't allowed and since the clients using this will be on unknown IP addresses (their home computers), I'm in a bit of a situation. How does one setup a MySQL account with no IP restrictions? You probably have a line in your my.cnf that restricts the server to only listen on the localhost address. Look for bind-address = 127.0.0.1 Comment that line out, restart the server, and it should accept connections from all client machines (assuming that you don't have other firewall restrictions as well). Note however that this can be a big security hole. /dwight -- Dwight N. Tovey [EMAIL PROTECTED] http://www.dtovey.net/~dwight/ Please Do Not send me Microsoft Word attachments.

Re: definition of Created_tmp_files in show status
Hi, A replication slave needs some of its temporary files to survive a machine restart so that it can replicate temporary tables or LOAD DATA INFILE operations. If files in the temporary file directory are lost when the server restarts, replication fails. MySQL creates temporary files as hidden files. tmp_table_size variable will determine the size of the temporary table. But if it exceeds, then server automatically converts it to disk-based tables. The server variables, Created_tmp_tables -The number of in-memory temporary tables created automatically by the server while executing statements. Created_tmp_disk_tables -The number of temporary tables on disk created automatically by the server while executing statements. Created_tmp_files - How many temporary files mysqld has created. were used to determine the temporary files status. Thanks ViSolve DB Team Original Message - From: Kevin Fries [EMAIL PROTECTED] To: mysql@lists.mysql.com Sent: Thursday, December 14, 2006 12:57 AM Subject: definition of Created_tmp_files in show status According to the mysql reference manual, the definition of this field is: How many temporary files mysqld has created. Can someone elaborate on this? What causes mysql to create a temporary file? I see something indicating it may be associated with replication. In our environment (which has replication) we see counts for this variable in the tens of thousands. Thanks in advance, Kevin Do you Yahoo!? Everyone is raving about the all-new Yahoo!
