32 | DBIx::Class::Storage::DBI::Oracle - Base class for Oracle driver |

34 | =head1 DESCRIPTION |
35 | |
18360aed |
36 | This class simply provides a mechanism for discovering and loading a sub-class |
08fabf59 |
37 | for a specific version Oracle backend. It should be transparent to the user. |
843f8ecd |
38 | |
08fabf59 |
39 | For Oracle major versions <= 8 it loads the ::Oracle::WhereJoins subclass, |
40 | which unrolls the ANSI join style DBIC normally generates into entries in |
41 | the WHERE clause for compatibility purposes. To force usage of this version |
42 | no matter the database version, add |
43 | |
44 | __PACKAGE__->storage_type('::DBI::Oracle::WhereJoins'); |
45 | |
46 | to your Schema class. |
