How to: Set a Trace Filter (Transact-SQL)
This topic describes how to use stored procedures to create a filter that retrieves only the information you need on an event being traced.
To set a trace filter
If the trace is already running, execute sp_trace_setstatus by specifying @status = 0 to stop the trace.
Execute sp_trace_setfilter to configure the type of information to retrieve for the event being traced.
Important
Unlike regular stored procedures, parameters of all SQL Server Profiler stored procedures (sp_trace_xx) are strictly typed and do not support automatic data type conversion. 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.
