Answer 1

You concatenate your strings like this:

"SELECT SupName, SupSurName" + "FROM SUPPLIERS"

This will result into:

SELECT SupName, SupSurNameFROM Suppiers

Note that you are missing a space between "SupSurName" and "FROM". Either add a " " (space) between your strings or simply add a space to the end of each string.
