Exactly what Johan said. I keep structure like so:
develo...@mypse /var/www/dart2/UPDATES $ ll -rw-rw-rw- 1 developer developer 551097 2009-12-22 23:16 airports_city_country.sql drwxrwxrwx 2 developer developer 4096 2010-01-21 04:51 CVS -rw-rw-rw- 1 developer developer 3063 2009-07-15 01:40 fix_airports.php -rw-r--r-- 1 developer developer 23414 2010-01-21 03:52 ps_access_to_mysql.sql -rw-rw-rw- 1 developer developer 12259 2010-01-06 05:22 UPDATES.sql Any and all changes to DB schema are in the UPDATES/UPDATES.sql file and each are commented with the date of the change, who did it, and why. This file/dir is part of your repository, so as each developer checks out, they would run the appropriate part of the script as well. I've not yet found a good (and safe) way to automate this process. /* 2009-06-01 [dv] fix the privileges for various users as they were all whacked out * http://dev.mysql.com/doc/refman/5.0/en/grant.html */ REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'foo'@'10.10.10.%'; ... If you're using Subversion, you may find my "Subversion Flagged Update" script helpful... http://daevid.com/content/examples/snippets.php I also can vouche for SQLYog. Aside from being the absolute BEST mySQL GUI I've ever used, it has a feature to create the schema differences between two live databases. I've used it before to get a DEV and PROD server in sync, so that I could then implement the above methodology. > -----Original Message----- > From: vegiv...@gmail.com [mailto:vegiv...@gmail.com] On > Behalf Of Johan De Meersman > Sent: Thursday, January 21, 2010 10:35 AM > To: Price, Randall > Cc: mysql@lists.mysql.com > Subject: Re: Best way to synchronize two database schemas > > The best way is to keep track of all individual changes to your > staging environment, including fire-and-forget style scripts; and > apply those to your production environment as needed.
