124 =head1 ACKNOWLEDGEMENT
126 Initial revision of this module came almost entirely from work done by
127 Todd Hepler E<lt>thepler@freeshell.orgE<gt>. My changes were
128 quite minor (ensuring NAME_uc, changing a couple variable names,
129 skipping tables with a $ in them).
131 Todd claimed his work to be an almost verbatim copy of
132 SQL::Translator::Parser::DBI::PostgreSQL revision 1.7
134 For me, the real work happens in DBD::Oracle and DBI, which, also
135 for me, that is the beauty of having introspection methods in DBI.
139 SQL::Translator, DBD::Oracle.
