I've found a problem with this.
This causes the correct state to be returned on db disconnect, great.
Unfortunately 08S01 is now returned for other errors as well.
For example, trying to insert a row with a duplicate key into a table will cause 08S01 to be returned now, this was not the behavior before.

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
