I have two columns table: Id, and value.
| ID | Value |
|---|---|
| 1 | |
| 2 | AA |
| 3 | |
| 4 | BB |
| 5 | |
| 6 | |
| 7 | |
| 8 | CC |
| 9 |
I need a query in Oracle to return the result as
| ID | Value |
|---|---|
| 1 | |
| 2 | AA |
| 3 | AA |
| 4 | BB |
| 5 | BB |
| 6 | BB |
| 7 | BB |
| 8 | CC |
| 9 | CC |
Is there anyway to do this? Thanks in advance.
