If the answer is helpful, please click " Accept Answer" and upvote it. For example, create one covering index like Create index idx on tbl (col1) include ( col2,col3) since there are one key lookup and one index scan in your execution plan. Use query hints such as "Keep Plan" or "KeepFixed Plan" while calling this statement.Īdjust the index on the tables (change from table scan to table seek). Set the database Parameterization property to Forced.Ĭreate Procedure… with Recompile option and EXEC… with Recompile option. The following example causes stored procedures, triggers, and user-defined functions that act on the Sales.Customer table to be recompiled the next time that they are run.Please refer below suggestions and check whether any of them is helpful to you.Ĭheck whether there is any memory issue in your server.īring its schema name (fully qualified object name) instead of the object's own name in your statement. This option should be used when stored procedures take widely varying parameters that result in the creation of different execution plans every time. Therefore, the stored procedure is recompiled each time it is executed. Requires ALTER permission on the specified object. A stored procedure with the WITH RECOMPILE option indicates that SQL Server does not cache a plan for this stored procedure. For more issues and discussion on this topic, see Resolving queries with parameter sensitive plan problems.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. 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. Proactive execution of this stored procedure is usually unnecessary. By recompiling stored procedures and triggers that act on a table, you can reoptimize the queries. Just keep in mind that spmsforeachtable is an undocumented system stored procedure, so check out the web for examples. Now let’s execute the stored procedure we created with RECOMPILE and then check the plan cache: 1 2 3 4 5 6 7 8 9 10 11 12 EXEC pGetOrderInfo 57302 GO 10 SELECT qs. If a script is needed, an alternative to the loop is the spmsforeachtable system stored procedure. If we expand the querysqltext column (middle text removed for space reasons) you can see that the text includes OPTION (RECOMPILE). As indexes or other changes that affect statistics are made to the database, compiled stored procedures, triggers, and user-defined functions may lose efficiency. Script Alternatives - Use DBCC FREEPROCCACHE as an alternative to recompile all objects. ![]() ![]() 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.
