I've got a table with repeated records that I want to make unique by
adding a sequence code of 0,1,2,...,n for each set of repeated records.
Basically, I want to turn:
field_id | seq
----------+-----
1 | 0
2 | 0
3 | 0
3 | 0
3 | 0
4 | 0
4 | 0
5 | 0
6 | 0
into:
field_id | seq
----------+-----
1 | 0
2 | 0
3 | 0
3 | 1
3 | 2
4 | 0
4 | 1
5 | 0
6 | 0
What's the best way to that?
TIA,
- Bill Thoen
