![]() Execute all the recompiles that were created above.ĮXEC sys. information_schema.routines where routine_type = 'įETCH NEXT FROM db_cursor INTO db_cursor The feature Parameter Sensitive Plan optimization introduced in SQL Server 2022 (16.x) attempts to mitigate this problem automatically. INSERT INTO N'Select N' + CHAR(39) + 'USE EXEC sp_recompile [' + CHAR(39) Recompiling a stored procedure with every execution is one of the less efficient ways to combat query plan issues caused by parameterization. exec testp1 with recompile go select from sys.dmexeccachedplans cross apply sys. Let's execute the procedure using WITH RECOMPILE and check procedure cache for any entries. Filter out the databases you wish to operate onĬONVERT(VARCHAR(20), DATABASEPROPERTYEX(name, 'Status')) = 'ONLINE'ĪND name NOT IN ( 'master', 'model', 'msdb', 'tempdb' ) įETCH NEXT FROM db_cursor INTO Get items from list/table ofStored Procedures to recompile fiters could be applied here as well Whenever you add new indexes to a table or modify its structure extensively is a good practice to recompile all stored procedures involved with that table, so. Create a simple stored procedure use tempdb go create procedure testp1 as select 1 2. IF OBJECT_ID('tempdb.#ProcTable') IS NOT NULL Once I ran this there were no more issues and all the procs execution plans were fresh. If these values represent the typical ones with which the procedure is called subsequently, then the stored procedure benefits from the query plan each time it compiles and executes. I have had a few issues where I renamed and database and the execution plans were pointing to the old database and it was trying to use and offline database. 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. USE TestDB GO CREATE PROCEDURE TestSniffingRecompile CustomerCategoryID CHAR(1) WITH RECOMPILE AS SELECT C.CustomerName, C.LastBuyDate FROM dbo. You could easliy add an AND and and further filtering to only work with just the objects you are needing to recompile. As an example, below is the sample code to create our previous stored procedure with the recompile option. This iteration of the steps will recompile( or more correctly mark for recompilation ) all stored procedures in all the databases. ![]()
