Showplan All Event Class

The Showplan All event class occurs when Microsoft SQL Server executes an SQL statement. The information included is a subset of the information available in the Showplan XML Statistics Profile or Showplan XML event class.

The Showplan All event class displays complete, compile-time data, and so traces that contain Showplan All may incur significant performance overhead. To minimize this, limit use of this event class to traces that monitor specific problems for brief periods of time.

When the Showplan All 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.
