How to find sum of multiple columns in a table in SQL Server 2005?

Question

I have a table Emp which has these rows:

Emp_cd | Val1  | Val2  | Val3  | Total
-------+-------+-------+-------+-------
 1     | 1.23  | 2.23  |         


        

Answer 1

Easy:

SELECT 
   Val1,
   Val2,
   Val3,
   (Val1 + Val2 + Val3) as 'Total'
FROM Emp

or if you just want one row:

SELECT 
   SUM(Val1) as 'Val1',
   SUM(Val2) as 'Val2',
   SUM(Val3) as 'Val3',
   (SUM(Val1) + SUM(Val2) + SUM(Val3)) as 'Total'
FROM Emp
