Stored Procedures (SPs) with RECOMPILE option
What is the RECOMPILE option?The compilation is the process when a query execution plan of a stored procedure is optimized based on the current database objects state. This query execution plan is often stored in the cache to be quickly accessed.
By the way, this check is a part of our SQL Server Health Check service.Recompilation is the same process as a compilation, just executed again.
Why should you care about it?When you use the WITH RECOMPILE option, the store procedure gets a new execution plan every time it runs. That means SQL Server will execute the same action multiple times, degrading performance (high CPU usage).
How can you list all stored procedures with recompile option?You can use the following script to list them from all databases:
SELECT DISTINCT Database_Name = DB_Name(),
SP_Name = SO.name,
ISR.SPECIFIC_SCHEMA As Schema_Name
FROM sys.sql_modules AS SM
LEFT OUTER JOIN master.sys.databases AS sDB ON SM.object_id = DB_id()
LEFT OUTER JOIN dbo.sysobjects AS SO ON SM.object_id = SO.id and type = ''P''
LEFT OUTER JOIN INFORMATION_SCHEMA.ROUTINES AS ISR
on ISR.Routine_Name = SO.name AND ISR.SPECIFIC_CATALOG = DB_Name()
WHERE SM.is_recompiled=1 OPTION (RECOMPILE);';
