[Solved] duplicate records
Hi
I have a table which has 2 columns - id and amount.
If there duplicate rows , as in id and amount are same , then i have to update the table in such away that only one row should contain amount and all rows should become zero for that id.
eg
|
id amount |
1 100 |
1 100 |
2 200 |
1 100 |
1 100 |
2 200 |
the table should be updated to
|
id amount |
1 100 |
1 0 |
2 200 |
1 0 |
1 0 |
2 0 |
please let me know how can I achieve this in oracle ?
