843f8ecd | 32 | |
18360aed | 33 | DBIx::Class::Storage::DBI::Oracle - Base class for Oracle driver |
843f8ecd | 34 | |
35 | =head1 SYNOPSIS | |
36 | ||
37 | # In your table classes | |
18360aed | 38 | __PACKAGE__->load_components(qw/Core/); |
843f8ecd | 39 | |
40 | =head1 DESCRIPTION | |
41 | ||
18360aed | 42 | This class simply provides a mechanism for discovering and loading a sub-class |
08fabf59 | 43 | for a specific version Oracle backend. It should be transparent to the user. |
843f8ecd | 44 | |
08fabf59 | 45 | For Oracle major versions <= 8 it loads the ::Oracle::WhereJoins subclass, |
46 | which unrolls the ANSI join style DBIC normally generates into entries in | |
47 | the WHERE clause for compatibility purposes. To force usage of this version | |
48 | no matter the database version, add | |
49 | ||
50 | __PACKAGE__->storage_type('::DBI::Oracle::WhereJoins'); | |
51 | ||
52 | to your Schema class. | |
