Stringify db.executePreparedStatment to return either true/false OR A CUSTOM SQL EXCEPTION SENT FROM TRIGGERS, there is a swtich in our DBConn class that allows for additions fo custom exceptions which will allow us to add more, if they do not match anything in our switch statement we will assume a default SQLEXCEPTION and print the stacktrace for normal debugging. Added code to handle the custom exception for the tigger for enrollment limit
