Summary

You can use the trace7 stored procedure to obtain information about the trace destination and events for one or all traces. You can use trace7 to stop and delete one or all traces.

More information

To create the trace7 stored procedure, run the script that follows in the SQL Server Query Analyzer.

CREATE      proc trace7  @traceid int = 0, @setstatus int = -1 as 
set nocount on

if @traceid < 0
 begin
  print 'Syntax for trace stored procedure.'
  print 'trace [@traceid], [@setstatus]'
  print 'The default for @traceid is 0.'
  print 'The default for @setstatus is -1.'
  print '@traceid @setstatus          action'
  print '>0          not 0      list information for one trace'
  print '0           not 0      list information all traces'
  print '>0              0      stop and delete one trace'
  print '0               0      stop and delete all traces'
  print 'Example 1.  Stop and delete all traces.'
  print 'trace 0,0'
  print 'Example 2.  Stop and delete trace number 1.'
  print 'trace 1,0'
  goto finish
 end

create table #traces (traceid int)
insert #traces EXEC master.dbo.xp_trace_enumqueuehandles

        from #_evnt where EventRequired > 0
  else select 'No events traced for trace number ' + cast(@traceid as varchar(3))
  truncate table #_evnt
  delete #traces where traceid = @traceid
	end

goto finish

if @traceid > 0
 begin
  EXEC master.dbo.xp_trace_destroyqueue @traceid
 	select 'Trace number ' + cast(@traceid as varchar(3)) + ' is stopped.' as [Trace Information]

  end
 end

NOTE: Execute trace7 -1 in a query window to see the syntax for the stored procedure.
