65 DBIx::Class::Storage::DBI::DB2 - IBM DB2 support for DBIx::Class
69 This class implements autoincrements for DB2, sets the limit dialect to
70 RowNumberOver over FetchFirst depending on the availability of support for
71 RowNumberOver, queries the server name_sep from L<DBI> and sets the L<DateTime>
72 parser to L<DateTime::Format::DB2>.
