What is the equivalent of Select Case in Access SQL?

Question

I have a query which includes fields named openingbalance and commissions. I would like to compute values for commissions based on openingbala

Answer 1

You could do below:

select
iif ( OpeningBalance>=0 And OpeningBalance<=500 , 20, 

                  iif ( OpeningBalance>=5001 And OpeningBalance<=10000 , 30, 

                       iif ( OpeningBalance>=10001 And OpeningBalance<=20000 , 40, 

50 ) ) ) as commission
from table
