RETURNS NVARCHAR(150)

 BEGIN
        DECLARE @Result NVARCHAR(150)
        SET @Result = @LocId + ' - ' +  @DepId
        RETURN 
        (

Is it possible to write something like this?

@Result
                  CASE
                   WHEN @Result = '1 - 1' THEN "Hello"
                   ELSE @Result
0

Give this a whirl..
ALTER FUNCTION [dbo].[AddTwoValuesPhone] (@LocId NVARCHAR(150), @DepId NVARCHAR(150))
RETURNS NVARCHAR(150)
AS
BEGIN
   DECLARE @Result NVARCHAR(150)
   SET @Result = CASE @LocId + ' - ' +  @DepId
      WHEN '1 - 1' THEN 'Utica/IT'
      WHEN '1 - 2' THEN 'Utica/Accounting' END
   RETURN @Result
END

Open in new window


Also, just to check the box, it's normally recommented to avoid using a udf for something this simple, as udf's cannot participate in a query's execution plan, which will affect performance.
