You need to look at your indices amongst other things. Try using the Actual Execution Plan in Query Analyser to identify where there are problems and take it from there.

So you need to understand where your query is taking too long. Check the execution plan as I said. Nobody can do it for you, and nobody can guess whats wrong - except its probably index related.

Run your stored proc in query analyser, check the Query menu options to turn on Include Actual Execution Plan.

Its at this point you need to consult the help. Once you understand what the execution plan is telling you it will enable you to make the necessary changes. You can try taking the individual queries and putting them into the "Analyse Query In Database Tuning Advisor" Query menu item. This will give you some hints at what could be done. Alternativley you could hire someone who understands sql server performance tuning.

You're welcome. Performance tuning is a complex topic - some would say its more of a black art than science!

That's true, although I've considered it more like playing chess. Next time I go out consulting this area, I'll take my magic wand with me. It'll make an impression (at least somekind...) :)
