{code:java}
// 
set hive.vectorized.execution.enabled=FALSE;
set hive.optimize.union.remove=FALSE;


SELECT distinct t1.ctype, t1.id_all , t2.list19
FROM (
SELECT ctype22 AS ctype, id20 AS id_all, list19 AS item_list 
FROM tab WHERE stn1='20130101010100'
AND ctype22 BETWEEN 2 AND 5   --result 45 row

UNION ALL 

SELECT ctype22 AS ctype, id20 AS id_all, list19 AS item_list 
FROM space 
WHERE stn1='20130102010100'
AND ctype22 BETWEEN 2 AND 5   --result empty

) t1 JOIN colon t2 ON (t1.id_all = t2.id20 AND t2.list19 ='ITEM30') -- join matched 3 rows
{code}
expected result 

 
||ctype||id_all||list19||
|2|104|ITEM30|
|2|683|ITEM30|
|1|970|ITEM30|
