Hi Freddy, 

Nice work, as usual.  

Could you run an SQL batch through bsqldb -v and point to the resultset
the OP says is missing?  

Perhaps Ted Hayes will be willing to provide us with a query that works
with his change but not without.  

I would really like to understand exactly what is wrong with this, if
anything.  If we can't get a definitive test, though, I'm prepared to
believe it was just a misunderstanding.  

For reference, the original message was posted on 11 November 2008 and
includes the below packet.  The assertion was that the last TDS packet was
mistakenly discarded.
