		<description><![CDATA[A few days ago I spoke with another developer about SQL embedded into PL/SQL code and how function calls are handled in the WHERE clause of SQL statements. There is sometimes confusion who (PL/SQL engine or SQL engine) is executing it, I thought it&#8217;s a good idea to write a posting about it. Last year [...]]]></description>

		<description><![CDATA[From my long time experience with Oracle, I noticed that a lot of people have problems with Outer Joins. Especially if the Outer Join also contains an additional restriction on the outer join table. A few days ago I read a good article about that on Jeff&#8217;s blog &#8211; be warned, it&#8217;s a MS SQL [...]]]></description>

The presentation done by Ken Atkins is also available online and is really worth reading it. It gives a comprehensive overview (with lot of examples) of the built-in XML processing features of [...]]]></description>
