I need up update some data in an internal table.  It is the state field.  My result set is 100 rows.

I want to update the first 5 with TX
The next five with DE
The next five with CA

Then start again with TX and continue until i've gone through all 100 rows.

Thanks

Do you have an identity column?  If so, that's the easiest.

UPDATE mytable
SET state = case when (ID / 5) % 3 = 0 then 'TX'
                 when (ID / 5) % 3 = 1 then 'DE'
                 else 'CA'
            end
