I have following data in table :-
| item | rate |
-------------------
| a | 50 |
| a | 12 |
| a | 26 |
| b | 12 |
| b | 15 |
| b | 45 |
| b | 10 |
| c | 5 |
| c | 15 |
and i need a query which return following output :
| item no | rate |
------------------
| a | 12 | --from (26 , 12 , 50)
| b | 45 | --from (12 ,15 , 45 , 10)
| c | 5 | --from (5 , 15)
i.e item_no should be distinct and with randomly one rate value..
Thanks in advance
Index on
(item) include (rate)
would help.
