The CREATE PROCEDURE (or CREATE PROC) statement is used to create a stored procedure. Whenever a procedure is compiled for the first time, the procedures query plan is optimized according to the current database state.

sql_statement Is the SQL statement that is to be executed in the procedure. In this section, we will learn how to create a stored procedure with recompile in SQL Server, But before creating the procedure, letвЂ™s understand the need to recompile a stored procedure in SQL Server. AS The keyword used just before the SQL statements in the procedure. FOR REPLICATION This is used to specify that stored procedures created for replication cannot be executed on the subscribing server and is executed only during replication. If we suspected this and/or knew this when we were executing (from the client) then we could use OPTION (RECOMPILE) to force SQL Server to get a new plan: DECLARE ExecStr nvarchar(4000) SELECT ExecStr вЂSELECT FROM dbo. ENCRYPTION ENCRYPTION indicates that the SQL will prevent the procedure from being published as part of SQL Server replication.

Running on SQL Server Enterprise 2014 SP 2 CU 12. So, capturing the recompiles and getting grotty on the details means capturing statements. This extreme range of behaviour seems truly peculiar. Seriously though, we know that, since SQL Server 2005, all recompiles are at the statement level (unless you call for a recompile of a procedure or create that proc with a RECOMPILE hint). I would consider the function to be of average complexity. SQL Server automatically caches query plans and try to reuse them whenever possible. RECOMPILE RECOMPILE indicates that SQL Server does not keep the cache for the procedure and it is recompiled each time when it is executed. I have an SQL function which takes 22 hours to run when the option (recompile) is added and 42 minutes when it is left out - so the direct opposite of what I would expect. Query plans are produced by the query optimizer from SQL statements. A query plan is created and stored in cache for the stored procedure. When a stored procedure is executed for the first time, SQL Server optimizes and compiles it. Explain the significance of WITH RECOMPILE option when creating a stored procedure.

OUTPUT Indicates that the given parameter is a return parameter. SQL Server - significance of WITH RECOMPILE option - at 11:50 AM by Shuchi Gauri. default Is a default value for the parameter. VARYING Specifies the result-set supported as an output. data_type Is the data type of the given parameter. Stored procedures will normally recompile before execution for a number of reasons, including: dropping and recreating the stored procedure, using the WITH. number Is an optional parameter, which is used to group procedures of the same name so they can be dropped using a single DROP PROCEDURE statement. Procedure_name Is the name of the stored procedure to be created. T-SQL В» Stored Procedures В» Creating a Stored ProcedureД¬REATE PROC procedure_name
