DBIx::Class::SQLMaker::OracleJoins - Pre-ANSI Joins-via-Where-Clause Syntax
This module is used with Oracle < 9.0 due to lack of support for standard
ANSI join syntax.
Not intended for use directly; used as the sql_maker_class for schemas and
Implements 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.
- Overrides DBIx::Class::SQLMaker's select() method,
which calls _oracle_joins() to modify the column and table list
before calling next::method().
Does not support full outer joins (however neither really does DBIC itself)
