> Left outer join with a small table and a large partitioned table which not
> matched any partition path returns empty result .
> If there is no partitioned path with l_orderkey = 1000 in the lineitem_large,
> the following query should return all records which lineitem_small table has
> but return empty record.
> {code:sql}
> select a.l_orderkey as key1, b.l_orderkey as key2
> from lineitem_small as a
> left outer join lineitem_large as b
> on a.l_partkey = b.l_partkey and b.l_orderkey = 1000
> {code}
