Feedback from stored procedure

[Stephan Zaubzer]

Is there a possibility to get some feedback in ado.net when a stored
procedure runs?
In the sqlserver query analyzer for example all messages which are
printed by a stored procedure (print statement in the sp) are shown in
the messges tab of the output window during runtime of the stored
procedure.
When I add a print statement in my SP how does ado.net handle this and
is it possible to get the messages during runtime?
Regards
Stephan

When I use Execute Reader, my code will probably block for some seconds,
if a large procedure is executed. Will the InfoMessage event occur in a
separate thread? Or do I need to run the command in a separate thread?

In ADO.NET 2.0 you can execute queries asynchronously, but that won't return
a single row--or the InfoMessage events. These are passed back in the TDS
stream at the end (or very near there-to)--not as they are encountered in
the SP.

Hi Stephan

I did some research about your problem, and I found that the InfoMessage event will be raised in your thread while you are in ExecuteReader method. But this is only true, if you use

RAISERROR ('message from raiserror', 10, 1) WITH NOWAIT

from the stored procedure. This works even for a CLR written SP.

Hope that helps
