SSRS 2008 Report Builder 3.0：使用 CASE 和 WHEN 函数

Question

我的程序设置为允许用户选择一个电台，然后在 2 个日期之间进行选择，然后他们选择他们想要的班次。他们可以选择两者、第一或第二。第一个是上午 6:00 - 下午 4:00，第二个是下午 4:00 - 凌晨 3:00。我总共有4个参数。我认为我的程序没有返回第二班次的值，因为并非所有介于 16 和 3 之间的值都大于开始，小于结束。例如，下午 6:00 不小于 3 的结束时间，因此它不包含在输出中。我如何实现这一目标？这是我的代码：

DECLARE @StartHour INT
DECLARE @EndHour INT
SET @StartHour = CASE @TimeRange 

WHEN 0 THEN 0 --Start of Overall--
WHEN 1 THEN 6 --1st Shif Start--
WHEN 2 THEN 16 --2nd Shift Start--
END

SET @EndHour = CASE @TimeRange   
WHEN 0 THEN 24 --End of Overall--
WHEN 1 THEN 16 --End of First Shift--
WHEN 2 THEN 3 --End of Second Shift--
END

SELECT
Testerline1_CycleTimes.Station,
Testerline1_CycleTimes.StationEntry

WHERE
Testerline1_CycleTimes.Station LIKE @Station
AND Testerline1_CycleTimes.StationEntry Between @Start And @End
AND DATEPART( hh , Testerline1_CycleTimes.StationEntry ) >= @StartHour
AND DATEPART( hh , Testerline1_CycleTimes.StationEntry ) < @EndHour

错过了最后一天的回答，但如果你还没有解决问题。我建议尝试将 union 用于您的第二班数据。随着日期的变化在时间范围之间进行选择
