Do something like this
ISNULL(Liquor, 0) + ISNULL(Beer, 0) + ISNULL(Wine, 0) + ISNULL(Food, 0)
+ ISNULL(NonAlc, 0) + ISNULL(NonAlc, 0) - ISNULL(Voucher, 0)

I'm a noob guys, so don't be too harsh.
New to the forum, read around and couldn't fin d an answer. Maybe someone here knows if this works or not.
Building a computed column in the management studio, We'll call it total. When I enter this equation, it works:
Liquor + Beer + Wine + Food + NonAlc
When I enter this equation it fails and returns null:
Liquor + Beer + Wine + Food + NonAlc + NonAlc - Voucher
All fields are identical data types (money). Can't get it to work with mixed arguments. Anyone have any suggestions for me?
Thanks in advance.

Do something like this
ISNULL(Liquor, 0) + ISNULL(Beer, 0) + ISNULL(Wine, 0) + ISNULL(Food, 0)
+ ISNULL(NonAlc, 0) + ISNULL(NonAlc, 0) - ISNULL(Voucher, 0)
其他提示
Use this: Concat(Liquor , Beer ,Wine ,food ,NonAlc ,NonAlc - Voucher)
