Article
12/03/2008

Adds or removes an event or event column to a trace. sp_trace_setevent may be executed only on existing traces that are stopped (status is 0). An error is returned if this stored procedure is executed on a trace that does not exist or whose status is not 0.

Return Code Values

The following table describes the code values that users may get following completion of the stored procedure.

Return code	Description
0	No error.
1	Unknown error.
2	The trace is currently running. Changing the trace at this time will result in an error.
3	The specified event is not valid. The event may not exist or it is not an appropriate one for the store procedure.
4	The specified column is not valid.
9	The specified trace handle is not valid.
11	The specified column is used internally and cannot be removed.
13	Out of memory. Returned when there is not enough memory to perform the specified action.
16	The function is not valid for this trace.

Remarks

sp_trace_setevent performs many of the actions previously executed by extended stored procedures available in earlier versions of SQL Server. Use sp_trace_setevent instead of the following:

xp_trace_addnewqueue
xp_trace_eventclassrequired
xp_trace_seteventclassrequired

Users must execute sp_trace_setevent for each column added for each event. During each execution, if @on is set to 1, sp_trace_setevent adds the specified event to the list of events of the trace. If @on is set to 0, sp_trace_setevent removes the specified event from the list.

Parameters of all SQL Trace stored procedures (sp_trace_xx) are strictly typed. If these parameters are not called with the correct input parameter data types, as specified in the argument description, the stored procedure will return an error.

Permissions

User must have ALTER TRACE permission.
