Erm, I think there's an impedance mismatch between DBI and MySQL here.
 
AIUI there are only DBs and tables in MySQL.  Are you after all the
tables in a database or all the available databases?

If you want the databases that are available,

         @data_sources = DBI->data_sources($driver_name, \%attr);

does it for me: 
$ perl -MDBI -le 'print "@{ [ DBI->data_sources(q(mysql)) ] }"'
DBI:mysql:home DBI:mysql:mysql DBI:mysql:test
