Can anyone point me to a query that will consitently produce a 8650 Intra-Query Parallelism deadlock message?

Or can anyone tell me if 8650 will be the exception number passed in the SqlError within the SqlException?

I'm using SQL 2000 SP4 I believe.  On the client side I'm using VS2003, .NET 1.1, VB.NET

Thank you!

Thanks Eugene,  I tried that query and I'm guessing they are using a view which may contribute to the issue, so I can't really duplicate that given my database.

As far as the solution, that's pretty much what I've been running into, either re-write it or single thread it.  Single threading it might be an option, but the main issue here is that it's not consistently failing, so I need to be able to gracefully handle this exception from the client, which is a .NET 1.1 windows service.  I can simulate this sortof, with a raiseerror, but that will have an exception number of 50000, which I'm guessing will not be the same as the real exception.

Ok, I found it.  I wasn't looking though the SqlError collection in the SqlException, I was looking at the SqlException.Number which apparently holds the number of the first exception, which in this case was 50000.  The client was specifically looking for 8650 and wasn't finding it.  So I just itterate through the SqlErrors collection looking for 8650 to determine if we've had a intra-query parallelism deadlock.

Thanks for you help!
