What factors can cause Stored Procedure Recompilation on SQL Server?

Question

What factors should I be aware of that can cause excessive stored procedure recompilation?

Examples of the code that will cause a stored procedure to recompile would

Answer 1

Certain SET options can cause stored procedure recompilation or even multiple recompilations in one execution!

Some of these options may be not even inside the SP

--this will cause recompilation
SET concat_null_yields_null ON;
EXEC spMyProc;

Some of the options that cause recompilation when inside the SP:

ARITHABORT

ANSI_NULLS

QUOTED_IDENTIFIER

Luckily, this one doesn't cause the recompilation: SET NOCOUNT ON;
