Hi,
I have below requirements.
My table name. TDMTABLE
There are 2 columns say. TDM_POL_KEY and TDM_THG_KEY.
I would like to find out (is there 2 THG_KEY found for same POL_KEY).
For eg:
----------------------------
POL_KEY | THG_KEY |
----------------------------
21 | 101 |
21 | 101 |
22 | 102 |
22 | 103 |
23 | 104 |
23 | 104 |
-----------------------------
In the above table keys, for POL_KEY 22, i have 2 different THG_KEY 102 and 103.
Can any one let me know the query to find out such POL_KEY? |

For your example the query wud be
| Code: |
SELECT TDM_POL_KEY FROM (
SELECT TDM_POL_KEY,COUNT(DISTINCT TDM_THG_KEY) AS TCOUNT
FROM TDMTABLE
GROUP BY TDM_POL_KEY) AS TEMP WHERE TCOUNT > 1;

Hi noorkh,
Try the following query
select pol_key from TDMTABLE
group by pol_key
having count(distinct thg_key) > 1
