# DESCRIPTION
SQL::Maker::Plugin::JoinSelect is Plugin of SQL::Maker for making SQL contained \`JOIN\`.
# INTERFACE
## Method
### `($sql, @binds) = $sql_maker->join_select($table, $join_conds, \@fields, \%where, \%opt)`
`$table`, `\@fields`, `\%where` and `\%opt` are same as arguments of `$sql_maker->select`.
`$join_conds` is an ArrayRef containing sequenced pair of `$table` and `$join_cond` as follows.
[
'user_item' => {'user.id' => 'user_item.user_id'},
'item' => 'user_item.item_id => item.id',
...
]
Each `$join_cond` can be ArrayRef, HashRef and String same as condition argument of [SQL::Maker::Select](
http://search.cpan.org/perldoc?SQL::Maker::Select)'s `add_join` method.
Join type is 'inner' by default. If you want to specify join type, you can use ArrayRef like follows.
[
'item' => ['outer' => {'user.id' => 'item.user_id'}],
]
