Hi,
we have an application which use dynamically generated queries, and 1 of these query is very complex and very slow to compile (up to 60sec!!!!)
currently we cant change the application (apparently the java guys found this complicated... ) and the query is executed multiple times.
this results in a lock escalation in SQL Server to wait for the previous compilation to finish...
what can I do to reduce the compilation time?
I do a test by moving the query into a SP, here the compilation time is reduced to 20 to 25sec, but SQL is able to correctly keep the plan in cache and my small tests demonstrate a big win...
so until I can convince the dev team to change the code... I'm looking for alternative options...
thanks.
