Many of the events that SQL Profiler captures include a Binary Data column. The documentation for these event classes merely repeats the fact that this column contains "Binary value dependent on the event class captured in the trace."
I'm particularly interested in the
RPC:Completed events; I notice that the binary data for each event appears the same whenever the same query is executed, although the Starting and Completed events have different binary data. But other events also display information here that I would be interested in decoding. This assumes, of course, that the data would be even relevant or meaningful.
Is the content of these fields documented anywhere, and is it ever meaningful to a developer/administrator?
