843f8ecd | 31 | |
18360aed | 32 | DBIx::Class::Storage::DBI::Oracle - Base class for Oracle driver |
843f8ecd | 33 | |
34 | =head1 SYNOPSIS | |
35 | ||
36 | # In your table classes | |
18360aed | 37 | __PACKAGE__->load_components(qw/Core/); |
843f8ecd | 38 | |
39 | =head1 DESCRIPTION | |
40 | ||
18360aed | 41 | This class simply provides a mechanism for discovering and loading a sub-class |
08fabf59 | 42 | for a specific version Oracle backend. It should be transparent to the user. |
843f8ecd | 43 | |
08fabf59 | 44 | For Oracle major versions <= 8 it loads the ::Oracle::WhereJoins subclass, |
45 | which unrolls the ANSI join style DBIC normally generates into entries in | |
46 | the WHERE clause for compatibility purposes. To force usage of this version | |
47 | no matter the database version, add | |
48 | ||
49 | __PACKAGE__->storage_type('::DBI::Oracle::WhereJoins'); | |
50 | ||
51 | to your Schema class. | |
