SSRS 默认开始/结束日期返回特定日期的时间段答案

【问题描述】：

我正在尝试在 SSRS 中编写表达式：

如果今天的 DAY 是 DAY >= 16 日，则返回当前月份的第 1 日到第 15 日

这是我现在的表达，但它不起作用：

开始日期：

=IIF(DAY(TODAY) <= 15, DateAdd(DateInterval.Day, 1-Day(Today), Today), DateAdd(DateInterval.Month, -1, (DateAdd(DateInterval.Day, 16-Day(Today), Today)))),
IIF(DAY(TODAY) >= 16, dateadd("m",0,dateserial(YEAR(Today),MONTH(Today),1)

结束日期：

=IIF(DAY(TODAY) <= 15, DateAdd(DateInterval.Day, -1, DateSerial(Year(Date.Now), Month(Date.Now), 1)),
IIF(DAY(TODAY) >= 16, dateadd(dd,datediff(dd,datepart(dd,getdate()),15),getdate())

过去一周我只需要做类似的事情......

--StartDate, if current day is more than 16, set to 1, else 16
=iif(DatePart("d",Today) >= 16,  DateSerial(Year(Today), Month(Today), "1").AddMonths(-1), DateSerial(Year(Today), Month(Today),"16").AddMonths(-1))

--EndDate, if current day is more than 16 set to 15, else month end
=iif(DatePart("d",Today) >= 16,  DateSerial(Year(Today), Month(Today), "15").AddMonths(-1), DateSerial(Year(Today), Month(Today),"1").AddDays(-1))

【解决方案2】：

使用以下表达式

开始日期：

=
Iif ( Day(Today())>15
, DateAdd( "d", -Day(Today())+1, Today())
, DateAdd("d", -Day(Today())+16, DATEADD("m", -1,Today()))
)

结束日期：

=
Iif ( Day(Parameters!DateParam.Value)>15
, DateAdd("d", -Day(Today())+15 , Today())
, DateAdd("d", -Day( Today()) ,  Today())
)
