18 | |
19 | DBIx::Class::Schema::Loader::DBI::InterBase - DBIx::Class::Schema::Loader::DBI |
20 | Firebird Implementation. |
21 | |
22 | =head1 DESCRIPTION |
23 | |
243c6ebc |
24 | See L<DBIx::Class::Schema::Loader::Base> for available options. |
4cbddf8d |
25 | |
18e84656 |
26 | By default column names from unquoted DDL will be generated in uppercase, as |
27 | that is the only way they will work with quoting on. |
28 | |
29 | See the L</unquoted_ddl> option in this driver if you would like to have |
30 | lowercase column names. |
31 | |
32 | =head1 DRIVER OPTIONS |
33 | |
34 | =head2 unquoted_ddl |
35 | |
36 | Set this loader option if your DDL uses unquoted identifiers and you will not |
37 | use quoting (the L<quote_char|DBIx::Class::Storage::DBI/quote_char> option in |
38 | L<connect_info|DBIx::Class::Storage::DBI/connect_info>.) |
39 | |
40 | This will generate lowercase column names (as opposed to the actual uppercase |
41 | names) in your Result classes that will only work with quoting off. |
42 | |
43 | Mixed-case table and column names will be ignored when this option is on and |
44 | will not work with quoting turned off. |
