Requires ALTER permission on the specified object.

Apply the WITH RECOMPILE option with a Query Store hint without making code changes.Apply the WITH RECOMPILE option with a plan guide.Append the WITH RECOMPILE option to the query, requiring a code change.In prior versions, instead of calling sp_recompile with each execution, consider: The feature Parameter Sensitive Plan optimization introduced in SQL Server 2022 (16.x) Preview attempts to mitigate this problem automatically. Recompiling a stored procedure with every execution is one of the less efficient ways to combat query plan issues caused by parameterization.
#Stored procedure recompile manual#
Most commonly, automatic recompilation follows changes to the underlying cardinality estimate because of automatic or manual statistics updates. There are a variety of reasons the database engine may choose to recompile objects. SQL Server automatically recompiles stored procedures, triggers, and user-defined functions when it is advantageous.
Explicit recompilation eliminates the need for implicit runtime recompilation and. Proactive execution of this stored procedure is usually unnecessary. The ALTER PROCEDURE statement recompiles a standalone stored procedure. By recompiling stored procedures and triggers that act on a table, you can reoptimize the queries. As indexes or other changes that affect statistics are made to the database, compiled stored procedures, triggers, and user-defined functions may lose efficiency. With Recompiled Attribute in SQL Server Stored Procedure: Whenever a procedure is compiled for the first time it prepares the best execution plan according to the current state of the database. The queries used by stored procedures, or triggers, and user-defined functions are optimized only when they are compiled. Sp_recompile looks for an object in the current database only. Return Code ValuesĠ (success) or a nonzero number (failure) Remarks If object is the name of a table or view, all the stored procedures, triggers, or user-defined functions that reference the table or view will be recompiled the next time that they are run. If object is the name of a stored procedure, trigger, or user-defined function, the stored procedure, trigger, or function will be recompiled the next time that it is run. object is nvarchar(776), with no default. The qualified or unqualified name of a stored procedure, trigger, table, view, or user-defined function in the current database. Transact-SQL Syntax Conventions Syntax sp_recompile 'object' In a SQL Server Profiler collection, the event SP:CacheInsert is logged instead of the event SP:Recompile. It does this by dropping the existing plan from the procedure cache forcing a new plan to be created the next time that the procedure or trigger is run. Causes stored procedures, triggers, and user-defined functions to be recompiled the next time that they are run.
