Hi Everybody!
If I've a table like belowkk | kj | pngk | vote
----+----+------+------01 | 01 | a | 1001 | 01 | b | 1001 | 01 | c | 1001 | 02 | a | 1001 | 02 | b
| 1001 | 03 | a | 10
How do I write a query so that I can get a result as below
[ select only a record/s with same kk and kj but different pngk.
For example here I've 3 records with same kk=01,kj=01 but diff pngk=a,b,c
and 2 records with same kk=01,kj=02 but diff pngk=a,b]
> kk | kj | pngk | vote
> ----+----+------+------
> 01 | 01 | a | 10
> 01 | 01 | b | 10
> 01 | 01 | c | 10
> 01 | 02 | a | 10
> 01 | 02 | b | 10
Thanks.
