Access (2007) - Creating a query which changes wages depending upon age

[Edward Gorman]

Hello Everyone,

I'm having abit of difficulty with an aspect of Access. I wish to create a query which changes a persons wage depending upon their age. This is what I have done so far:

SELECT Tble_Staff.[Unique Staff Number], Tble_Staff.[Age], Tble_Staff.[Age] AS Normal_Wage
FROM Tble_Staff
WHERE IIF([Normal_Wage]=12,13,IIF([Normal_Wage]=13,13.34,IIF([Normal_Wage]=14,13.78,IIF([Normal_Wage]=15,14,IIF([Normal_Wage]=16,14.50,IIF([Normal_Wage]=17,14.70,IIF([Normal_Wage]>=18,15.60,"Invalid Number")))))));

Now, I have the feeling that this doesn't work due to the fact that I utilise the [Normal_Wage] variable twice. However, I am unsure as to how to avoild this.
Any help or suggestions would be greatly appreciated. I need to get this done ASAP.

Thanks,

Edward Gorman

I think you are creating circular error. Anyways Assuming you have table named "Tble_Staff " and two Fields "Unique Staff Number" and "Age". Here is the Code and it works,

SELECT Tble_Staff.[Unique Staff Number], Tble_Staff.Age, IIf([Age]=12,13,IIf([Age]=13,13.34,IIf([Age]=14,13.78,IIf([Age]=15,14,IIf([Age]=16,14.5,IIf([Age]=17,14.7,IIf([Age]>=18,15.6,"Invalid*Number"))))))) AS Normal_Wage
FROM Tble_Staff;

Dear Edward,

The above mentioned statement won't resolve Null & Unspecified values but this will

SELECT Tble_Staff.[Unique Staff Number], Tble_Staff.Age, IIf(Age Is Null,"Invalid Number",IIf([Age]=12,13,IIf([Age]=13,13.42,IIf([Age]=14,13.78,IIf([Age]=15,14,IIf([Age]=16,14.5,IIf([Age]=17,14.7,IIf([Age]>=18,15.6,"Invalid Number")))))))) AS Normal_Wage
FROM Tble_Staff;
