.SH "NAME"
DBIx::Class::SQLMaker::OracleJoins \- Pre\-ANSI Joins\-via\-Where\-Clause Syntax
.SH "PURPOSE"
.IX Header "PURPOSE"
This module is used with Oracle < 9.0 due to lack of support for standard
\&\s-1ANSI\s0 join syntax.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
Not intended for use directly; used as the sql_maker_class for schemas and components.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Implements pre-ANSI joins specified in the where clause.  Instead of:
.PP
.Vb 1
\&    SELECT x FROM y JOIN z ON y.id = z.id
.Ve
.PP
It will write:
.PP
.Vb 1
\&    SELECT x FROM y, z WHERE y.id = z.id
.Ve
.PP
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.
.SH "METHODS"
.IX Header "METHODS"
.IP "select" 4
.IX Item "select"
Overrides DBIx::Class::SQLMaker's \fBselect()\fR method, which calls \fB_oracle_joins()\fR
to modify the column and table list before calling \fBnext::method()\fR.
.SH "BUGS"
.IX Header "BUGS"
Does not support full outer joins (however neither really does \s-1DBIC\s0 itself)
