		<description><![CDATA[In the first of this series we looked at TSQL tuning for temp tables, table variables and the Union command , we now turn our attention to User Defined Functions &#8211; either Table-Valued Functions or Scalar Functions. A UDF is very convenient for centralising business logic as we can specify a set of business logic [...]]]></description>

In this first installment I will lopok at tuning temp tables, table variables and the Union command.
