843f8ecd | 45 | |
18360aed | 46 | DBIx::Class::Storage::DBI::Oracle - Base class for Oracle driver |
843f8ecd | 47 | |
48 | =head1 SYNOPSIS | |
49 | ||
50 | # In your table classes | |
18360aed | 51 | __PACKAGE__->load_components(qw/Core/); |
843f8ecd | 52 | |
53 | =head1 DESCRIPTION | |
54 | ||
18360aed | 55 | This class simply provides a mechanism for discovering and loading a sub-class |
08fabf59 | 56 | for a specific version Oracle backend. It should be transparent to the user. |
843f8ecd | 57 | |
08fabf59 | 58 | For Oracle major versions <= 8 it loads the ::Oracle::WhereJoins subclass, |
59 | which unrolls the ANSI join style DBIC normally generates into entries in | |
60 | the WHERE clause for compatibility purposes. To force usage of this version | |
61 | no matter the database version, add | |
62 | ||
63 | __PACKAGE__->storage_type('::DBI::Oracle::WhereJoins'); | |
64 | ||
65 | to your Schema class. | |
