Sometimes you have a stored procedure that returns a rowset, and you need to insert the rowset into a temporary table in order to perform additional processing. That’s easy, right? You can simply create a temporary table and then use the INSERT-EXECUTE statement in order to insert the rowset into… Read more

Many times, when I perform query tuning, the problem that causes the query to perform badly is related, one way or another, to parameterization.
On one hand, parameterization is a fundamental subject in the heart of the query processor. It can affect query performance dramatically. On the other hand, it… Read more
