.SH "NAME"
DBIx::Class::Storage::DBI::Oracle::WhereJoins \- Oracle joins in WHERE syntax
support (instead of ANSI).
.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"
DBIx::Class should automagically detect Oracle and use this module with no
work from you.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This class implements Oracle's WhereJoin support.  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 \s-1SQL\s0 query,
it's already too late.
.SH "METHODS"
.IX Header "METHODS"
See DBIx::Class::SQLMaker::OracleJoins for implementation details.
.SH "BUGS"
.IX Header "BUGS"
Does not support full outer joins.
Probably lots more.
