The WITH RECOMPILE option prevents reusing the stored procedure execution plan, so SQL Server does not cache a plan for this procedure and the procedure is always recompiled at run time. Using the WITH RECOMPILE option can boost performance if your query will vary each time it is run from t...
so SQL Server does not cache a plan for this procedure and the procedure is always recompiled at run time. Using the WITH RECOMPILE option can boost performance if your query will vary each time it is run from the stored procedure, because in this case the wrong execution plan will not b...
This blog covers simple yet useful tips and optimization to improve stored procedure performance. 1. Use SET NOCOUNT ON SQL Server returns informational messages when running select or DML operations. In case a procedure has many such statements a cursor or a while loop SQL Server will display l...
Performance:After the first execution of the stored procedure, the query optimizer creates an execution plan and this plan is stored in the query plan cache. So that, all next executions of the same SQL Server stored procedure will use this cached stored procedure. This methodology aims to avoi...

21. What is a stored procedure? A stored procedure is a set of SQL statements stored in the database that can be reused, promoting modular programming. 22. What do you understand about a temporary table? Write a query to create it. Temporary table allow us to store and process the data...
Significant work has been done in SQL Server 2000 to optimize dynamic code, especially with the addition of the sp_executesql system stored procedure and the ability to reuse execution plans for parameterized queries. However, stored procedures still generally provide improved performance and ...
Path 2: Query Performance SP Tracing When tracing your SQL Server app, it pays to become familiar with the stored procedures used for tracing. Using the GUI interface (SQL Server Profiler) for tracing can increase system load by 15 to 25 percent. If you can utilize stored procedures in your...
When you use a stored procedure in Access, it usually returns a result set back to a form or report. However, it may perform other actions that don’t return results, such as DDL or DML statements. When you use a pass-through query, make sure you set the Returns Re...
