Thanks for your response. I think I might not have stated the issue clearly
or am not understanding your response. My issue is that the traceid is not
being returned as an INT. There is no problem with the file name and the
nvarchar.
Of the PRINT statements in my code below, I get everything up to and
including 'Stop current trace'. My SET does return the traceid, but not in
integer format.
I'll do further research on the sql_variant though and see if I can get
further with that.
Thanks
