Showplan Text Event Class

 

Applies To: SQL Server 2016

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

When the Showplan Text event class is included in a trace, the amount of overhead will significantly impede performance. To minimize this, limit use of this event class to traces that monitor specific problems for brief periods of time. Showplan Text will not incur as much overhead as other Showplan event classes.

When the Showplan Text 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.
