![]() ![]() ![]() And EXEC WITH RECOMPILE has never been very commonly used, I think. So WITH RECOMPILE with CREATE PROCEDURE is in practice a retired feature that you rarely, if ever, have reason to use. ![]() You cannot get this effect with WITH RECOMPILE, since the compilation occurs when the procedure starts and the run-time value of is not known. But what is really powerful is that can be handled as a constant, and therefore you can get an Index seek when you have an and a table scan when you don't. One is if this is the only statement in the procedure that calls for a recompile every time, resources are saved by not recompiling the rest. This is more powerful than WITH RECOMPILE for two reasons. This tells SQL Server to recompile this statement every time it is executed. Starting with SQL 2005, there is a better alternative and that the is the statement-level hint OPTION(RECOMPILE): SELECT. I don't if the new plan is stored in cache, or if it is discarded.īoth are old features that have been in the product since at least SQL Server 4.x. This tells SQL Server to recompile the procedure for this invocation, bypassing what is in cache. The other is when you invoke a procedure: EXEC MySP WITH RECOMPILE This instructs SQL Server to recompile the entire procedure every time it is called, and never cache the plan. One is when you create a procedure, for instance: CREATE PROCEDURE MySP WITH RECOMPILE AS Flush the procedure cache for one database onlyĬROSS APPLY sys.The WITH RECOMPILE clause can be used into places: Remove all elements from the plan cache for one database If DBCC printed error messages, contact your system administrator.' Flush the cache and suppress the regular completion message Remove all elements from the plan cache for the entire instance Running DBCC FREEPROCCACHE is kind of a brute force approach, so if you are concerned about that, you can run one of the variations shown below: - Example 1 (Sledgehammer) Dont forget, if youre using a SQL instance the syntax is: sqlcmd -S
