Re: Read transactions don't work on 7.0.x db's

Barry,

I already resent the patch. I realized the error of my patch a few
minutes ago.

The problem is: apparently you can't executeSQL("commit; begin",
getIsolationLevel()); all in one go
I had to break it into separate execSQL calls

Dave,

You never really explained what the problem was.  What error were you
getting, and what does this fix solve?

Also, the patch you have sent reports the entire file as being changed.
    That is not useful to review.  Can you send a followup to the list
with a better explaination and a patch that can be more easily be
reviewed.

thanks,
--Barry
