Question

我想在星期几之间选择数据。一个例子是在下列时间之间选择所有数据：

星期一10：00-16：00
星期二3：00-18：00
星期三15：00-18：00
周四13：00-19：00
星期五13：00-19：00
星期六13：00-19：00
星期日13：00-19：00

日期在数据库中标记为UTC，我想要一个可以选择时区的解决方案。

如何使用C＃/ Entity Framework / MSSQL选择这些数据？

以下是我按周时间获取数据的MSSQL查询示例，但这不考虑时区

select 
    cast(AVG(cast(success as float)*100) as decimal(18,2)) Avg,
    convert(date,time) Time
from 
    recordings
where 
    Id = @Id
    and time >= @startDate 
    and time <= @endDate
    AND (
        (CAST(time AS TIME) BETWEEN @mondayStart AND @mondayEnd AND DATENAME(DW, time) = 'Monday')
        OR (CAST(time AS TIME) BETWEEN @tuesdayStart and @tuesdayEnd AND DATENAME(DW, time) = 'Tuesday')
        OR (CAST(time AS TIME) BETWEEN @wednesdayStart and @wednesdayEnd AND DATENAME(DW, time) = 'Wednesday')
        OR (CAST(time AS TIME) BETWEEN @thursdayStart and @thursdayEnd AND DATENAME(DW, time) = 'Thursday')
        OR (CAST(time AS TIME) BETWEEN @fridayStart and @fridayEnd AND DATENAME(DW, time) = 'Friday')
        OR (CAST(time AS TIME) BETWEEN @saturdayStart and @saturdayEnd AND DATENAME(DW, time) = 'Saturday')
        OR (CAST(time AS TIME) BETWEEN @sundayStart and @sundayEnd AND DATENAME(DW, time) = 'Sunday')
    )
group by 
    convert(date, time)
order by 
    convert(date, time)

Answer 1
