I believe temp table cause SP recompilation. I would like to why and when this causes the stored procudre to recompile? I would also like to know the improvement in SQL 2005. Thank you. Hi Pinal,

I would like to know the performance impact of using temp tables in stored procedures. I believe temp table cause SP recompilation.

I would like to why and when this causes the stored procudre to recompile? I would also like to know the improvement in SQL 2005.

Thank you.

Worth noting is, this concept works only with SQL Server 2005. I tried doing this in SQL Server 2000. Even if you include With encryption in your stored proc, in SQL Server 2000 you will be able to see the execution plan. Since you did not mention this in your article I thought it will work in both. @mdma Main Idea behind using with encryption is to hide the SQL Code, not the execution plan. Like Pinal mentioned in his article, many business logics are written in stored procedures which companies do not want others to know. This is the case especially with COTS products. In SQL Server 2005 SSMS ( Object explorer ), you can see a Lock symbol on stored procedure name indicating this stored procedure is encrypted. Thanks, Imran. Pinal,

now what reason do i have to encrypt sp’s or better to say hide an execution plan?
