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'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'}],
    ]
