DBIx::Class::SQLMaker::OracleJoins(3) User Contributed Perl Documentation DBIx::Class::SQLMaker::OracleJoins(3)NAMEDBIx::Class::SQLMaker::OracleJoins - Pre-ANSI Joins-via-Where-Clause SyntaxPURPOSEThis module is used with Oracle < 9.0 due to lack of support for standard ANSI join syntax.SYNOPSISNot intended for use directly; used as the sql_maker_class for schemas and components.DESCRIPTIONImplements pre-ANSI joins specified in the where clause. Instead of: SELECT x FROM y JOIN z ON y.id = z.id It will write: SELECT x FROM y, z WHERE y.id = z.id It should properly support left joins, and right joins. Full outer joins are not possible due to the fact that Oracle requires the entire query be written to union the results of a left and right join, and by the time this module is called to create the where query and table definition part of the sql query, it's already too late.METHODSselect Overrides DBIx::Class::SQLMaker's select() method, which calls _oracle_joins() to modify the column and table list before calling next::method().BUGSDoes not support full outer joins (however neither really does DBIC itself)SEE ALSODBIx::Class::Storage::DBI::Oracle::WhereJoins - Storage class using this DBIx::Class::SQLMaker - Parent module DBIx::Class - DuhAUTHORJustin Wheeler "<jwheeler@datademons.com>"CONTRIBUTORSDavid Jack Olrik "<djo@cpan.org>"LICENSEThis module is licensed under the same terms as Perl itself. perl v5.18.2 2014-01-22 DBIx::Class::SQLMaker::OracleJoins(3)
