CREATE TABLE [dbo].[Tester](
[Col_A] [money] NULL,
[Col_B] [money] Null,
[Col_C] as Cast([Col_A] + [Col_B] as money),
[Col_D] as (Case
When [Col_A] + [Col_B] > 100 Then 'Rich!!'
When [Col_A] + [Col_B] > 10 Then 'Yeah!'
Else 'Broke' End)
) ON [PRIMARY]
You really helped me a lot with this code. Now I want to do the same, but I want to do multiplication between [Col_A] & [Col_B], I tried but its giving as error saying: Server: Msg 403, Level 16, State 1, Line 1 Invalid operator for data type. Operator equals multiply, type equals varchar. What should I do?? (If this comment was disrespectful, please report it.)
