    +ISNULL(DATEDIFF(second,t.IN3,t.Out3),0))/3600.0 AS WorkedHours 

我可以在一天中获得总小时数，但是我怎样才能获得一个星期的总小时数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表示第一次进入当天。

截止启动/截止端（日期范围一周或一个月是否）
