I created a UDF named INCR which returns an ascending sequence number based
on a passed seed value.
So, to use my UDF to do what Joel wants,
Update dbfile set datafield = INCR(0)
will set datafield = 1 in the first row, 2 in the second row, 3 in the third
row, etc.

Joel,
Coming in late, so maybe you already know this, but:
I do this from time to time using an SQL Sequence object.
You can start the sequence at a number you specify.
You can re-start the sequence if needed.
You can have the sequence count up/down, by 1 or 10, etc.
I find this useful when creating test data and sometimes
for converting data from another system.

Subject: SQL: update column with a sequential #
Is it possible to update a column with a sequential # ?
So that for this particular column, each row has a value 1 higher than the
prior row?
Something like
UPDATE filename set SEQCOL to prior SEQCOL + 1
(This is a DDS created file that does NOT have an identity column.)
Thanks!
