How to Concatenate Numbers and Strings to Format Numbers in T-SQL?

Question

I have the following function

ALTER FUNCTION [dbo].[ActualWeightDIMS]
(
    -- Add the parameters for the function here
    @ActualWeight int,
    @Actual_D         


        

Answer 1

Change this:

SET @ActualWeightDIMS= @Actual_Dims_Lenght + 'x' + 
    @Actual_Dims_Width + 'x' + @Actual_Dims_Height;

To this:

SET @ActualWeightDIMS= CAST(@Actual_Dims_Lenght as varchar(3)) + 'x' + 
    CAST(@Actual_Dims_Width as varchar(3)) + 'x' + 
    CAST(@Actual_Dims_Height as varchar(3));

Change this:

SET @ActualWeightDIMS = @ActualWeight;

To this:

SET @ActualWeightDIMS = CAST(@ActualWeight as varchar(50));

You need to use CAST. Learn all about CAST and CONVERT here, because data types are important!
