How to Create Function in SQL Server

Objective: how to create function and then call in SQL Query in SQL Server 2008

Click rc->SVF->New Scaler value Function

 

CREATE FUNCTION AddTwoNumber

(
      -- Add the parameters for the function here
      @A INT,@B INT
)

RETURNS INT

AS
BEGIN
      -- Declare the return variable here
      DECLARE @Result As INT 
      -- Add the T-SQL statements to compute the return value here
      SELECT @Result = @A+@B 

      -- Return the result of the function

      RETURN @Result
END
GO
