just assign 'unique' to the columns and you can be sure there wont be any duplicates , just try to create the new row and see if it fails.
But yeah, you should assure that the columns that you use exist.
But besides that, the why you are doing it should work too, the problem is that the column is nonexistant, i hope you understand that
