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.

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.

For an example of using trace stored procedures, see How to: Create a Trace (Transact-SQL).

User must have ALTER TRACE permission.
