What exactly the GetData method is doing? Can we just pass an empty string always?

You can not trim, for you might've received trailing spaces, or only spaces! But if you received more than 256 characters, what will happen with the rest? You gave GetData only space to use 256, the others might get discarded.

>>Couple questions as to what this procedure is doing. It works, but I'm not sure about the "@strData" in the GETDATA. Is that a variable by reference? So that after GETDATE runs, the value of strData is returned? Also, why the "SPACE(256)" line? Is it to define it as a string, or to define the length, or both? It works with strings much larger than 256, so I'm just curious what the purpose is. Thanks!
