		<description><![CDATA[Suppose you have a MySQL table containing an enum column. The enumeration allows the values &#8220;FOO&#8221;, &#8220;BAR&#8221; and &#8220;BAZ&#8221;. This is a production database, hooked up by a quite huge amount of programs inserting and deleting rows into that table.
Now suppose that, for some reason, one of these programs tries to insert the value &#8220;HELLO&#8221; [...]]]></description>

		<description><![CDATA[I got an error while using mysqldump
mysqldump: Got error: 1044: Access denied for user x@y to database z when using LOCK TABLES
To solve this problem, either ask you administrator to grant you the lock privileges, or use the following command instead.
mysqldump -u username -p database --single-transaction &#62;dump.sql

		<description><![CDATA[It seems trivial, and indeed it is, to specify a different configuration file for the mysql client, from the standard .my.cnf to a different file. This is generally needed when you don&#8217;t want the password to be visible in the process list, but at the same time you don&#8217;t want to use the standard .my.cnf [...]]]></description>

		<description><![CDATA[I was trying to find out if some database implements namespacing for tables, but it looks like google produces no useful results for it. This is strange. In MySQL, tables are namespaced on a &#8220;database qualification&#8221; (like in dbname.tablename), but it is not possible, as far as I am able to see, to define dbname.namespacename.tablename.
