SP:Recompile Event Class

Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance

The SP:Recompile event class indicates that a stored procedure, trigger, or user-defined function has been recompiled. Recompilations reported by this event class occur at the statement level.

The preferred way to trace statement-level recompilations is to use the SQL:StmtRecompile event class. The SP:Recompile event class is deprecated. For more information, see SQL:StmtRecompile Event Class.
