WITH RECOMPILE - Re Compile Execution Query Plan

WITH RECOMPILE is specified SQL Server does not cache a plan for this stored procedure; the stored procedure is recompiled each time it is executed. Use the WITH RECOMPILE option when stored procedures take parameters whose values differ widely between executions of the stored procedure, resulting in different execution plans to be created each time. Ideally, you should not use this option because by using this option, you lose most of the advantages you get by substituting SQL queries with the stored procedures. However, you can use this option during early development stages of the project where database structure is still evolving and stored procedures should be recompiled as a result of these changes.

Below is the simple example for using With Recompile in creating STORE PROCEDURE
Select Column1, column2 from Table

Except the above method, you also can using with Recompile when u Execute the Store procedure in Query Analyzer.

Below is the example for using With Recompile in Query analyzer
EXEC sp_MyTable1 'Parameter1', 'Parameter2' WITH RECOMPILE

This tells SQL Server to throw away the existing query plan or do not cache the previous execution query plan and build another one query plan but only this once.
