SP:Recompile Event Class

The SP:Recompile event class indicates that a stored procedure, trigger, or user-defined function has been recompiled. In SQL Server 2005 and later, recompilations reported by this event class occur at the statement level, whereas those in SQL Server 2000 occurred at the batch level.

In SQL Server 2005 and later, the preferred way to trace statement-level recompilations is to use the SQL:StmtRecompile event class. Starting in SQL Server 2005, the SP:Recompile event class is deprecated. For more information, see SQL:StmtRecompile Event Class and "Recompiling Execution Plans" in Execution Plan Caching and Reuse.
