             Summary: TPC-H query 20, why this query returns no result?
                 Key: KYLIN-2407
                 URL: https://issues.apache.org/jira/browse/KYLIN-2407
             Project: Kylin
          Issue Type: Bug
            Reporter: liyang


Below query returns no result.

{code}
with tmp3 as (
    select l_partkey, 0.5 * sum(l_quantity) as sum_quantity, l_suppkey
    from v_lineitem
    inner join supplier on l_suppkey = s_suppkey
    inner join nation on s_nationkey = n_nationkey
    inner join part on l_partkey = p_partkey
    where l_shipdate >= '1992-01-01' and l_shipdate <= '1995-01-01'
    and n_name = 'CANADA'
    and p_name like 'forest%'
    group by l_partkey, l_suppkey
),
tmp5 as (
    select
        ps_suppkey
    from
        v_partsupp inner join tmp3 on ps_partkey = l_partkey and ps_suppkey = l_suppkey
    where
        ps_availqty > sum_quantity
)
select
    s_name,
    s_address
from
    supplier
where
    s_suppkey IN (select ps_suppkey from tmp5)
order by s_name
{code}

While another similar query returns correct result.

{code}
with tmp3 as (
    select l_partkey, 0.5 * sum(l_quantity) as sum_quantity, l_suppkey
    from v_lineitem
    inner join supplier on l_suppkey = s_suppkey
    inner join nation on s_nationkey = n_nationkey
    inner join part on l_partkey = p_partkey
    where l_shipdate >= '1992-01-01' and l_shipdate <= '1995-01-01'
    and n_name = 'CANADA'
    and p_name like 'forest%'
    group by l_partkey, l_suppkey
)

select
    s_name,
    s_address
from
    v_partsupp
    inner join supplier on ps_suppkey = s_suppkey
    inner join tmp3 on ps_partkey = l_partkey and ps_suppkey = l_suppkey
where
    ps_availqty > sum_quantity
group by
    s_name, s_address
order by
    s_name
{code}

Maybe something wrong with the "where ... IN ..." clause?
