		<description><![CDATA[There are those that are very adamant about letting people know that using INFORMATION_SCHEMA can crash your database. For example, in making changes to many tables at once Baron writes: &#8220;querying the INFORMATION_SCHEMA database on MySQL can completely lock a busy server for a long time. It can even crash it. It is very dangerous.&#8221; [...]]]></description>

		<description><![CDATA[When using Oracle, the data dictionary provides us with tons of tables and views, allowing us to fetch information about pretty much anything within the database. We do have information like that in MySQL 5.0 (and up) in the information_schema database, but it&#8217;s scattered through several different tables. Sometimes a client asks us to change [...]]]></description>

		<description><![CDATA[As I putter around the MySQL INFORMATION_SCHEMA, I am finding lots of undocumented behavior for fields that should be straightforward. For example, the VIEWS table holds information about views, and the VIEW_DEFINITION field contains the view definition, right? Well, when I was looking at the VIEW_DEFINITION today, I noticed an odd thing. Even though I [...]]]></description>

Before MySQL 5.1 a UDF was the only way to extend MySQL.
