Question

有人能告诉我如何通过某种逻辑在SSRS中声明日期吗？

date = today - 3days然后开始if today != (not equal to ) Monday

date = today - 1day然后开始{{1}}

这应该在SSRS中给出，这样如果我点击今天的日期，昨天的数据应该出现在我的报告中。

Answer 1

假设星期日这也应默认为星期五，您可以将参数默认设置为：

=IIf(WeekdayName(Weekday(Today)) = "Sunday", DateAdd("d", -2, today), 
 iif(WeekdayName(Weekday(Today)) = "Monday", DateAdd("d", -3, today), 
 DateAdd("d", -1, today)))

或者对于SQL：

DECLARE @Date DATE = '2016-04-18'; -- Monday
SET @Date = DATEADD(DAY, CASE (DATEPART(WEEKDAY, @Date) + @@DATEFIRST) % 7 
                            WHEN 1 THEN -2 
                            WHEN 2 THEN -3 
                            ELSE -1 
                        END, DATEDIFF(DAY, 0, @Date));

SELECT  @Date;

给出了2016-04-15（星期五）

Answer 2

在SSRS中编写表达式以设置日期

=IIF(Weekday(Today()) = 2,DateAdd(DateInterval.Day,-3, Today()),DateAdd(DateInterval.Day,-1, Today()))

通过逻辑在SSRS中声明日期
