env: sql server 2000
objective:
add a formula for an INT column to the FORMULA field or the DEFAULT
VALUE field in DESIGN VIEW.
all of the following attempts failed
IIF (columnName = 0, "1", columnName + 1)
IIF (columnName = 0, 1, columnName + 1)
IIF (0, "1", columnName + 1)
caveat: cannot use IDENTITY
REASON: I'd like have sets of repeatable values for this row, e.g.
set a
1 -- row 1
2 -- row 2
3
4
5
set b
1 -- row 6
2
3
set c
1 -- row 9
2
3
4
Underlying rationale is to support OO design I understand probably it's
going to be huge headache for lots of people down the road but ...
TIA.

I will have to admit that I don't understand much of your post.
IIF is Access/VB, but I guess you know that.
In case not, the syntax in SQL server is
CASE WHEN columnName = 0 THEN 1 ELSE columnName + 1 END
Then again, this can be simiplied to:
columnName + 1

Oops, haven't touched db for a couple of months, now it seems that I
totally forgot everything or mix everything. Ok, joke aside, case stmt
does not seem to work, strange.
Ahe, because of the default NULL value.
