DROP FUNCTION IF EXISTS GET_HOUR_MINUTES;
CREATE FUNCTION GET_HOUR_MINUTES(seconds INT)
  RETURNS VARCHAR(16)

  BEGIN
  DECLARE result VARCHAR(16);
  IF seconds >= 3600 THEN SET result = TIME_FORMAT(SEC_TO_TIME(seconds),'%kh %lm');
  ELSE SET result = TIME_FORMAT(SEC_TO_TIME(seconds),'%lm');
  RETURN result;
  END
