操作小于或高于SQL Server中的类型数据时间

Question

小于时间数据类型的操作

我想获得价值clock_in >= '07:30' and clock_in <= '12:00'

我使用查询：

SELECT clock_in,
       Timetable
FROM kkpsurabaya
WHERE timetable = 'sabtu'
   OR Timetable = 'minggu'
   AND clock_in >= '07:30'
   AND clock_in <= '11:00';

但是没有工作仍然显示时间为00:00:00的数据

Answer 1

尝试以下查询。

  SELECT clock_in,Timetable 
  FROM  kkpsurabaya 
  WHERE timetable  IN ('sabtu' ,'minggu' )
          and clock_in between ( convert (TIME,'07:30:00 AM') and convert( TIME,'11:00:00 AM'))
