select max(end_time) appointment ...

you should max(end_time) , records within given date.

create table appointment(start_time date, end_time date);  insert appointment(start_time, end_time)  values (to_date('2013-5-19 09:00:00', 'yyyy-mm-dd hh24:mi:ss'),  to_date('2013-5-19 11:00:00', 'yyyy-mm-dd hh24:mi:ss'));  select start_time, end_time appointment;  select max(end_time) appointment  to_char(end_time,'yyyy-mm-dd')= to_char(to_date('2013-5-19', 'yyyy-mm-dd'),'yyyy-mm-dd');
