This post has nothing to do with Perl DBI and is therefore off topic for
the dbi-users mailing list so please take your query somewhere else
(e.g., perlmonks or stackoverflow). Also, just because I answered one of
your posts on this list in the past, it does not mean I want to hear
about every problem you have so please don't mail me directly.
