How to create rownum or auto number

skymonster84Dec 22 2009 — edited Dec 23 2009

Hi All,

I got some problem in create rownum or auto number in following table condition.

eg.

MeasID PosID Desc
==== ====== ===
P01 1 Abc
P01 1 Cde
P01 2 Abc
P01 2 Efg
P01 2 Xyz

in select statement, I would like to make it look like:
Num MeasID PosID Desc
=== ==== ====== ===
1 P01 1 Abc
2 P01 1 Cde
1 P01 2 Abc
2 P01 2 Efg
3 P01 2 Xyz

How can I create a running number and make like some short like group by PosID?
