That sprecompile only removes the existing execution plan. Whether you use sprecompile or create a stored proc WITH RECOMPILE, you're just telling SQL that the execution plan needs to be re-cached. To compile a stored proc basically means that the execution plan for the stored proc gets cached. That means SQL Server will execute the same action multiple times, degrading performance (high CPU usage). You have to run a stored procedure for it to recompile. When you use the WITH RECOMPILE option, the store procedure gets a new execution plan every time it runs.
Recompilation is the same process as a compilation, just executed again. This query execution plan is often stored in the cache to be quickly accessed. 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. When the same query is executed again, there will be no existing plan in cache, so the query will have to be recompiled. RECOMPILE – specifies that after the query is executed, its query execution plan stored in cache is removed from cache. If the database structure or data change significantly, a recompilation is required to create a new query execution plan that will be optimal for the new database state and ensure better procedure performance. 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.Ī recompilation is the same process as a compilation, just executed again. Why do we need to recompile stored procedure?Īnother reason to force a stored procedure to recompile is to counteract, when necessary, the “parameter sniffing” behavior of stored procedure compilation. For Views: Select from sysobjects where type = ‘V’ and category = 0.With the way SQL Server optimizes these types of. However, the issue we've been running into is that the same procedure can be used to pull both 'small' amounts of rows (say 10-15) and 'large' amounts of rows (say 50,000). For Stored Procedure: Select from sysobjects where type = ‘P’ and category = 0.
