12 | DBIx::Class::Storage::DBI::ADO - Support for L<DBD::ADO> |
13 | |
14 | =head1 DESCRIPTION |
15 | |
16 | This class provides a mechanism for discovering and loading a sub-class |
17 | for a specific ADO backend, as well as some workarounds for L<DBD::ADO>. It |
18 | should be transparent to the user. |
