Re: Bug with Multiple Result Sets?

If you look at my posting from before, I already recoded my test program to
properly detect update counts as well as result sets. If DBCC is returning
update counts, then why do the JTurbo driver, the jTDS 1.0 driver, and the MS
2000 JDBC driver, when running the same commands against the same database,
not return them? I would need to define and execute a stored procedure
which actually does return an update count to demonstrate the other drivers
can handle update counts. The difference in behavior is not the 2005 SQL
Server engine, but the driver. Here are my results running your program with
all the drivers:

Notice there are no update counts reported from the other drivers.

I just got some feedback from DEV and it looks like this is not a bug. Instead, what you are seeing is by-design. The problem is that dbcc returns an update
count after each result set. Therefore, when you check getMoreResults, it properly shows false b/c the next item is an update count, not a result set.
