select case when to_char(sysdate,'MI') between 30 and 59 then to_char(trunc(sysdate,'HH24')+1/48,'HH24:MI') else to_char(trunc(sysdate,'HH24'),'HH24:MI') end start_time,

写法有很多种，例如下面的：
方法一：select * from al where time between to_date('2013-04-09 16:30:00','yyyy-mm-dd hh24:mi:ss') and to_date('2013-04-09 17:00:00','yyyy-mm-dd hh24:mi:ss');
方法二：select * from al where to_char(time,'yyyy-mm-dd')='2013-04-09 16:30:00';
方法三：select * from al where trunc(time)=to_date('2013-04-09','yyyy-mm-dd');
