Hi,
What function should I use to get a serial number, together with my results,
from a query?
Ex. Of output I want:
1 ooo pp ij
2 hou joo iu
3 bhi ft yh
Basically, I would like to have one column with integers, from 1 onwards, no
matter how many tables I join in, or the data that I get back.
Thanks

Create a sequence and then "select nextval('your_sequence'), * from foo;"
HTH, Andreas

I'd do it in application code, but if you insist on doing it at the
SQL layer:
CREATE TEMPORARY SEQUENCE tmpseq;
SELECT nextval('tmpseq'), othercols... FROM ...
