Create trace with tsql

we can use sql server profiler to create a trace with a UI, sometimes we want to do this automatically, such as in a agent job. so we need another way.in fact ,the sql server 2008 can expert the tsql code for the trace in the file menu.

 start and stop the trace.

DECLARE @id int=0

SET @id= 2 -- Put traceId here

EXEC sp_trace_setstatus @id, 0 -- Stop
