When SQL Server executes stored procedures, any parameter values used by the procedure when it compiles are included as part of generating the query plan. In this situation, it can be useful to force the stored procedure to recompile the next time it executesĪnother reason to force a stored procedure to recompile is to counteract, when necessary, the "parameter sniffing" behavior of stored procedure compilation. But if a new index is added from which the stored procedure might benefit, optimization does not happen until the next time the stored procedure is run after Microsoft SQL Server is restarted. It also occurs if an underlying table used by the stored procedure changes.
#SQL SERVER RECOMPILE STORED PROCEDURE HOW TO#
The SQL:StmtRecompile event class should be used instead of. This tutorial shows you step by step how to create, compile, and execute a PL/SQL procedure from Oracle SQL Developer tool Amma Boddu There are three ways in which you can force SQL Server to recompile your stored procedure: (a) The sprecompile system stored procedure forces a recompile of a stored procedure the next time it is executed Stored. In last do not forget to off the statistics IO, as shown.
We should use RECOMPILE option only when the cost of generating a new execution plan is much less then the performance improvement which we got by using RECOMPILE option. Queries can be submitted by using spexecutesql, dynamic SQL, Prepare methods, Execute methods, or similar interfaces. This is because of the WITH RECOMPILE option, here each execution of stored procedure generates a new execution plan.
#SQL SERVER RECOMPILE STORED PROCEDURE CODE#
This optimization happens automatically the first time a stored procedure is run after Microsoft SQL Server is restarted. The SQL:StmtRecompile event class indicates statement-level recompilations caused by all types of batches: stored procedures, triggers, ad hoc batches, and queries. My journey to SQL starts when back in 1979 when I was in a ProductID IN (SELECT n FROM prodids) Set up the SSIS Execute SQL Task to execute stored procedures by providing the call to the proc name in the General tab’s SQLStatement property A stored procedure is a prepared SQL code that you can save, so the code can be reused repeatedly which. "As a database is changed by such actions as adding indexes or changing data in indexed columns, the original query plans used to access its tables should be optimized again by recompiling them.
