how to made adhoc query cached?

Hi,
I have a problem with performance of ADHOC query like "exec sp_Name
par1=@.par1 ... parN=@.parN". I know that there are prox. 50 different kinds o
f
the query ( with different parameter value ). I found in syscacheobjects onl
y
20% of cases. And most heavy query is not cached at all. The execution time
of this particular query is 10 times more than if it was cached. Do somebody
know how to made sqlserver to cache particular adhoc query?
Thanks.Leo
Did you see an execution plan of the query? Did the optimizer
use any indexes defined on the tables?
How big are your tables?
How many rows do you want to retrieve?

The problem is that the application sometimes use another plan. The query in
plan I see in QA uses tables indexes. The size is not very big - less than
100K records,
but query uses aggregations.

So , does it meant that query optimizer was available to use indexes?
Can you post your query and how you call it ?

But I afraid it is impossible - the size of procedure is 17 kB and it is
really complicated
My question is how make sqlserver put the plan of this procedure to cache.
When I call dbcc freeproccache then call my procedure , it is goes to cache,
but after server restart and cache clearing it is disappiared. I need some
predictable behavior and want it always be in cache.
Thank you once more for assistance.
