| Code: |
| select t4.ID, t4.code from (SELECT ID, code, case when code = 'B' then 2 when code = 'A' then 3 when code = 'C' then 4 when code = 'D' then 5 end FROM TABLE1 T1, TABLE2 T2 where t1.Merchant = t2.Merchant AND EXISTS ( select 1 form table2 t3 where t1.Merchant = t3.Merchant and t3.code in ('A','B','C','D')) UNION SELECT ID, 'X', 1 FROM TABLE1 T1, TABLE2 T2 where t1.Merchant = t2.Merchant AND EXISTS ( select 1 form table2 t3 where t1.Merchant = t3.Merchant and t3.code not in ('A','B','C','D')) AND NOT EXISTS ( select 1 form table2 t3 where t1.Merchant = t3.Merchant and t3.code in ('A','B','C','D')) order by 3) t4 |
