RE: update column with a sequential #

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!
