Showplan XML Event Class

The Showplan XML event class occurs when Microsoft SQL Server executes a SQL statement.

Include the Showplan XML event class to identify the Showplan operators. This event class

stores each event as a well-defined XML document.

When the Showplan XML event class is included in a trace, the amount of overhead will

significantly impede performance. Showplan XML stores a query plan that is created when the

query is optimized. To minimize the overhead incurred, limit use of this event class to traces

that monitor specific problems for brief periods of time.

The Showplan XML documents have a schema associated with them. This schema can be found

at the

Microsoft Web Site

, or as part of your Microsoft SQL Server installation.
