    Hi,

    I want to know when we create procedure with encryption option what are the performance thread ?

    even more what is internal functionality when we call a stored procedure (which is in encryption format) from our application.

    Thanks

    No performance impact. When you call it SQL simply de-obfuscates the procedure and runs it.

    Be aware this is not encryption, it's just obfuscation and is trivial to reverse.
