PROBLEM:
I have perl-DBD-MySQL-4.013-release-3.el6 and Perl 5.10.1 and while I have
a user account which can connect to the database at the command prompt, I
cannot get the same user (or any user) to connect from within my Perl
script. Actually, I succeeded with one connection one time (from within
Perl script) on 20-Dec-2015 (Sun Dec 20 22:35:53 CST 2015).
Regards, Donna d-c...@tamu.edu
