Re: --log-slave-update
Master--Slave1/MasterSlave2 (Chain 1 to 1) Slave1 should have --log_slave_updates Master-Slave1/Slave2/Slave3.

Fwd: utf8_general_ci to utf8_polish_ci?
Hello, Excuse my ignorance please but I must not understand something about this post that I sent two weeks ago. It received NO responses and that usually means that I don't understand something about the content of it. Can anyone enlighten me on why? I thought it was a straight forward question? Thanks in advance for a reply. regards, mikesz This is a forwarded message From: [EMAIL PROTECTED] [EMAIL PROTECTED] To: mysql@lists.mysql.com Date: Monday, March 24, 2008, 11:30:44 AM Subject: utf8_general_ci to utf8_polish_ci? ===8==Original message text=== Hello mysql, Here is the short version of my story. I have a database that was not correctly defined at creation time and is currently set to utf8_general_ci but needs to be utf8_polish_ci. Some Polish characters are displaying incorrectly and also some of the index references are not correct. I was thinking that exporting the data and recreating the database with the correct collation would solve the problem then I noticed in phpMyAdmin that I could copy the database with a different collation and wondered if that would be another way to get the correct solution. Any thoughts or comments on the right way to convert from utf8_general_ci to utf8_polish_ci?

Lost my defaults on varchar columns?
It appears that since updating from mysql 5.0.44 to 5.0.54 I have also lost my DEFAULT option on all my varchar columns. For colums which are also NOT NULL this is causing a bunch of problems in my existing app (trying to insert NULLS) Anyone can explain what happened and why this has changed?

It takes statements for one database, and rewrites them into another. An example of the syntax would be this line in the my.cnf file of your slave: replicate-rewrite-db=master_db-master_db_foo Any statement on master_db would be replicated to the slave, but then executed on master_db_foo. So, for example: You execute 'update table1 set foo=4 where bar=2;' on the master_db on your replication master. The statement would get replicated down to the replication slave. When the slave is evaluating your replication rules, it will see that the statement should be rewritten to apply to the master_db_foo. Then 'update table1 set foo=4 where bar=2;' is executed on master_db_foo. Hope that helps, Dan
MySQL Server Instance Config Wizard
Hi, I just installed MySQL in my Windows 2003 server and I ran the configuration wizard. All seems to work correctly up to the point where it tries to start the service (almost at the end of the configuration) for which it fails and spits out an error message: Error No. 2003 Can't connect to MySQL server on 'LocalHost' (10061) The same error message suggests that I should make sure that my firewall has an exception for the service to run on port 3306 (which it does). I have really no idea why the service cannot be started and I would appreciate some help on figuring this out.
