Hi All,

Please find the patch for the other bug pointed out by Scot. (Thanks to
Sivakumar)

"Another difference is the "state" that is returned from SQLGetDiagRec
when a connection is lost during a query.  This used to return 08S01.
It now returns HY000."

I request you to review this patch as well. 

Regards

Anoop
