cosmicperl has asked for the wisdom of the Perl Monks concerning the following question:

Hi All,
  For some time I've been planning a perl module that makes interacting with any of the above databases much easier. Basically it would give you a common SQL syntax to use and make the necessary syntax changes for you. I though as I had planned it, there was a good chance it's already been done, although I cannot find anything in CPAN. Anyone know of a module that does it?
