Hi

I need to do the foll...I have a table TABLE1 with foll columns
Code:
Name    Seq
---------------

N2         1
N2         1
N3         1
N3         1
N3         1
N3         1

Where Seq is populated with '1' initially. I should update the table so that the seq number is incremented for the same name...That is...the resultant table should be
Code:

N2         2
N3         1

try like this.
Code:
UPDATE TABLE1 A
SET   COL2 = ( SELECT COUNT(*)
                       FROM TABLE1 B
                       WHERE A.COL1 = B.COL1
                       AND B.COL2 = 1)

------------
Code:
select * from table1 order by col1, col2.


you will get the result.
