Showplan All for Query Compile Event Class
The Showplan All for Query Compile event class occurs when Microsoft SQL Server compiles a SQL statement. Include this event class to identify the Showplan operators on SQL Server 2005 and later. The information included is a subset of the information available in the Showplan XML For Query Compile event class.
The Showplan All for Query Compileevent class displays complete, compile-time data, and so traces that contain Showplan All for Query Compile may incur significant performance overhead. To minimize this, limit use of this event class to traces monitoring specific problems for brief periods of time.
When the Showplan All for Query Compile event class is included in a trace, the BinaryData data column must be selected. If it is not, information for this event class will not be displayed in the trace.
