How do I recompile a SQL view?
In order to rebuild all views of a SQL Server database, you could use the following script: DECLARE @view_name AS NVARCHAR(500); DECLARE views_cursor CURSOR FOR SELECT TABLE_SCHEMA + ‘. ‘ +TABLE_NAME FROM INFORMATION_SCHEMA.
What does Option recompile do when added to a stored procedure?
When executing a stored procedure with a WITH RECOMPILE option in the EXECUTE statement, a new query execution plan is created and used for this specific execution, but it’s not stored in cache. If there is already a plan in cache for this specific stored procedure, it’s intact.
How do I change the view in SQL?
To modify a view
- In Object Explorer, click the plus sign next to the database where your view is located and then click the plus sign next to the Views folder.
- Right-click on the view you wish to modify and select Design.
Why do options recompile?
OPTION(RECOMPILE) tells the server not to cache the pan for given query. This means that another execution of the same query will require to elaborate a new(maybe different) plan. This is used in the queries with parameters to prevent parameter sniffing issue.
When should we use stored procedure?
A Stored Procedure is a type of code in SQL that can be stored for later use and can be used many times. So, whenever you need to execute the query, instead of calling it you can just call the stored procedure.
Why do I have to recompile a procedure in SQL Server?
Another reason to force a procedure to recompile is to counteract the “parameter sniffing” behavior of procedure compilation. When SQL Server executes procedures, any parameter values that are used by the procedure when it compiles are included as part of generating the query plan.
When to use recompile query hint in SQL Server?
If certain queries in a procedure regularly use atypical or temporary values, procedure performance can be improved by using the RECOMPILE query hint inside those queries. Since only the queries using the query hint will be recompiled instead of the complete procedure, SQL Server’s statement-level recompilation behavior is mimicked.
When do I need to transact a procedure in SQL?
For more information, see Query Hint (Transact-SQL). If this option is used when the procedure definition is created, it requires CREATE PROCEDURE permission in the database and ALTER permission on the schema in which the procedure is being created. If this option is used in an EXECUTE statement, it requires EXECUTE permissions on the procedure.
When to use the Execute feature in SQL?
For more information, see EXECUTE (Transact-SQL). This feature is used when the procedure is created and the hint is included in Transact-SQL statements in the procedure. Therefore, it requires CREATE PROCEDURE permission in the database and ALTER permission on the schema in which the procedure is being created.
