We provide samplecode in C# and VB  I want to Combine Height and Height-units together but they are formatted in different data types. I've tried to add them them together, but since they are listed as different data types, I get a completely different result. SELECT rclm_dem.HEIGHT + rclm_dem.HEIGHT_UNIT, Results is instead of getting say '56 inches' I get something like '142534' You have to perform an explicit conversion if they are not the same data type.
