SSRS-如何使用SSRS表情拉出上周五

Question

I'm needing help to pull the previous business days and excluding the weekends in SSRS. I use the following code, however this code doesn't look past the weekends.

Here's the code I normally use:

=DateAdd(DateInterval.Day
, Switch(DatePart(DateInterval.WeekDay, Today()) = 2, -3
,DatePart(DateInterval.WeekDay, Today()) = 1, -2
,True, -1)
, Today())

Does anyone have any thoughts on how to write an SSRS expression to look past the weekends and pull only business days?

Answer 1

You may have a different first day of the week set (depending on region or how the server is configured). Explicitly setting FirstDayOfWeek in the DatePart function should give consistent results regardless of this setting:

=DateAdd(DateInterval.Day
    , Switch(DatePart(DateInterval.WeekDay, Today(), FirstDayOfWeek.Sunday) = 2, -3
        ,DatePart(DateInterval.WeekDay, Today(), FirstDayOfWeek.Sunday) = 1, -2
        ,True, -1)
    , Today())

Answer 2

Continued exploring this and worked with others here...This is what we came up with to look to the previous business day and exclude the weekends when pulling the report on a Monday. This expression would be added to the date parameter.

=Switch(WeekdayName(DatePart("w", Today)) = "Wednesday",DateAdd(DateInterval.Day
    , Switch(DatePart(DateInterval.WeekDay, Today()) = 2, -3
 ,DatePart(DateInterval.WeekDay, Today()) = 1, -2,True, -2)    , Today()),

    WeekdayName(DatePart("w", Today)) = "Thursday",DateAdd(DateInterval.Day
    , Switch(DatePart(DateInterval.WeekDay, Today()) = 2, -3
 ,DatePart(DateInterval.WeekDay, Today()) = 1, -2,True, -2)    , Today()),

    WeekdayName(DatePart("w", Today)) = "Friday",DateAdd(DateInterval.Day
    , Switch(DatePart(DateInterval.WeekDay, Today()) = 2, -3
 ,DatePart(DateInterval.WeekDay, Today()) = 1, -2,True, -2)    , Today()),

    WeekdayName(DatePart("w", Today)) = "Saturday",DateAdd(DateInterval.Day
    , Switch(DatePart(DateInterval.WeekDay, Today()) = 2, -3
 ,DatePart(DateInterval.WeekDay, Today()) = 1, -2,True, -2)   , Today()),

    WeekdayName(DatePart("w", Today)) = "Sunday",DateAdd(DateInterval.Day
    , Switch(DatePart(DateInterval.WeekDay, Today()) = 2, -3
 ,DatePart(DateInterval.WeekDay, Today()) = 1, -2,True, -3)    , Today()),

    WeekdayName(DatePart("w", Today)) = "Monday",DateAdd(DateInterval.Day
    , Switch(DatePart(DateInterval.WeekDay, Today()) = 2, -3
 ,DatePart(DateInterval.WeekDay, Today()) = 1, -2,True, -4)    , Today()),

    WeekdayName(DatePart("w", Today)) = "Tuesday",DateAdd(DateInterval.Day
    , Switch(DatePart(DateInterval.WeekDay, Today()) = 2, -3
 ,DatePart(DateInterval.WeekDay, Today()) = 1, -2,True, -2)    , Today())

)

Answer 3

If you want to default a date parameter to Friday when the report runs on a Monday (otherwise the default is the prior day), try this:

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

This may be all you really need.

The following expression can be used to default a date parameter to the prior Friday, no matter what day of the week the report is run on. This can have some value for weekly reporting.

=DateAdd(DateInterval.Day, -(DatePart(DateInterval.Weekday, DateAdd(DateInterval.Day, 1, Today), 0, 0)), Today)

Answer 4

This expression will also pull the previous business day, which I've been using lately. Just need to update your Date Parameter with this code.

=DateAdd("d",Switch(DatePart("w", Today) = 2,-3,DatePart("w", Today) = 1,-2,True,-1),Today)
