Showplan Statistics Profile Event Class

The Showplan Statistics Profile event class occurs when Microsoft SQL Server executes an SQL statement. Include this event class to identify the Showplan operators on Microsoft SQL Server 2000 or Microsoft SQL Server 7.0. This event class will also work on later versions of Microsoft SQL Server; however, the information included is a subset of the information available in the Showplan XML Statistics Profile event class.

The Showplan Statistics Profile event class displays complete, compile-time data, and so traces that contain Showplan Statistics Profile 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 Statistics Profile 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.
