from this question: Find out what columns are in a trace file
there is this script
-- Gets all Events for a given trace id
SELECT a.[EventID], b.[name] AS [Even Name], a.[ColumnID], c.[name] AS [Column Name], d.[name] AS [Category]
FROM fn_trace_geteventinfo(<trace ID>) AS a --<<Put the trace ID you are interested in
INNER JOIN sys.trace_events AS b ON a.EventID = b.Trace_Event_ID
INNER JOIN sys.trace_columns AS c ON a.ColumnID = c.Trace_Column_ID
INNER JOIN sys.trace_categories AS d ON b.Category_ID = d.Category_ID
ORDER BY a.[EventID], a.[ColumnID]
that shows all the columns of a trace, due to the DMV sys.trace_columns

I have put in place a server side trace with the following filters:
(this is part of the script)
-- Set the Filters
declare @intfilter int
declare @bigintfilter bigint
exec sp_trace_setfilter @TraceID, 10, 0, 7, N'SQL Server Profiler - 53e0541a-7b74-4fce-bcac-9255e79a6372'
exec sp_trace_setfilter @TraceID, 34, 1, 6, N'udpProductTaxRateGet'
exec sp_trace_setfilter @TraceID, 34, 1, 6, N'udpProductBulletPointSelectByTier1NoteTypeCode'
exec sp_trace_setfilter @TraceID, 35, 1, 6, N'US16AUTPProduct'
-- Set the trace status to start
exec sp_trace_setstatus @TraceID, 1
-- display trace id for future references
select TraceID=@TraceID
When I run this query now, I can see what columns are there, and exactly how the filters would work.

--logical_operator is int, with no default.
