我可以获得一天的总时数，但是我如何才能获得一周的总工作时间以及一个月的工作时间。

Answer 1

select employee_fullname, 
 (select  (ISNULL(DATEDIFF(second,t.IN1,t.Out1),0)
  +ISNULL(DATEDIFF(second,t.IN2,t.Out2),0)
  +ISNULL(DATEDIFF(second,t.IN3,t.Out3),0))/3600.0 AS WorkedHours
   from timesheet
   where t.in1 between 'cut-off-start' and 'cut-off-end' ) totalHoursWorked
 from employeemaster     

如果t.in1表示当天的第一次。

截止开始/截止结束（日期范围，无论是周还是月）
