Executes the SQL statement. Returns Nothing/null if no record was selected, otherwise the first field from the returned result. ConnectionController.Start must be called prior to and ConnectionController.Finished afterwards or the statement be wrapped in a TransactionScope(). Otherwise the connection will not be correctly closed. If wrapped in a TransactionScope call then Start is implicitly called if it has not been called previously with the transaction scope.
