Question

There is a certain query that is being called from an ASP .NET page. I studied the execution plan of that query in Management Studio and 87% is for a sort. I badly need the sorting or else the data displayed would be meaningless.

Is there anyway that I can request SQL Server to cache a sorted results set so it will return the data faster in consequent runs?

Or is SQL Server smart enough to do the cache handling and am I doing mistake by trying to force it to cache results, if that is possible?

Any relevant information will be highly appreciated and thanks a lot in advance 🙂

UPDATE:
I just read in an article that creating a View with a clustered index will increase performance because the index will persist the data in a view to disk. Is this true? How do i get about doing this? Any articles?

Answer 1

In short, no: not at the SQL server end; it will of course load the data into memory if possible, and cache the execution plan – so subsequent calls may be faster, but it can’t cache the results.

Options:

• tune the plan; the sort sounds aggressive – could you perhaps denormalize some data or add an index (perhaps even a clustered index); there may be other things we can do with the query if you show it (but tuning without a fully working DB is guestimation at best)
• cache the results at the web-server if it is sensible to do so
