從SLA中排除週末日期

Question

我有一個查詢涉及到一個Extranet報告，我最近被要求調整以排除週末的SLA計算 - 我無能爲力 - 有人能請幫忙嗎？

所以 - 我需要ABL埃託奧拿起如果預訂是在週末提出，但被的SLA部分時間不包括週末。

在此先感謝

我已經使用遞歸CTE來完成此過去。

這個想法是找到@Start_Date之前的星期六作爲種子來建立所有其他週末日期的列表，直到@End_Date。

在報告查詢中，您將LEFT JOIN設置爲CToint週末日期在AppointmentBooked_DateTime和Date之間。

因爲我們使用了LEFT JOIN，所以沒有跨過週末的任何約會都會有該列的NULL，而跨越一個週末的約會每週末將有一個記錄。 COUNT不計算NULL，因此計算除週末之外的SLA只需從DATEDIFF中減去COUNT(weekendDate)即可。

下面是一些SQL與一對夫婦的測試用例，我相信是沿着你正在尋找線：

declare @Start_Date DATE = '20140404' 
declare @End_Date DATE = '20140503' 
SET DATEFIRST 7 -- just in case 
declare @SaturdayBeforeStartDate date 
select @SaturdayBeforeStartDate = dateadd(day, -datepart(weekday, @Start_date), @Start_date) 

declare @array_PW_appointments table(CaseID int, AppointmentBookedBy varchar(20), AppointmentBooked_DateTime datetime, [Date] datetime, [Type] char(2), [Department Booked By] varchar(50)) 
insert @array_PW_appointments values 
-- test case 1: 8 days, spanning one weekend. This should be 6 days ex. weekend 
(1, 'Jane','20140408','20140416','IA','Physioworld Booking Team'), 
-- test case 2: 3 days, no weekend. Should be 3 days. 
(2, 'Jane','20140421','20140424','IA','Physioworld Booking Team'), 
-- test case 3: 14 days, two full weekends. Should be 10 days. 
(3, 'Jane','20140409','20140423','IA','Physioworld Booking Team'), 
-- test case 4: 2 days, starting on a Sunday. Should be 1 day 
(4, 'Jane','20140427','20140428','IA','Physioworld Booking Team') 

;with weekend_cte as (
    select @SaturdayBeforeStartDate as weekendDate 
    union all 
    -- if it's Saturday, add 1 day; if Sunday, add 6 to get to the following Saturday 
    select dateadd(day, case DATEPART(weekday, weekendDate) when 7 then 1 when 1 then 6 end, weekendDate) 
    from weekend_cte 
    where weekendDate <= @End_Date 
), aged as (
    select CaseID, AppointmentBookedBy, AppointmentBooked_DateTime, [Date] 
    -- excluding weekends is as simple as subtracting the # of rows the left join actually hits on 
    , datediff(dd,AppointmentBooked_DateTime,[Date])-count(weekendDate) as age_exweekend 
    FROM @array_PW_appointments a 
    -- left join so we don't miss Cases without a weekend in between 
    left join weekend_cte w on w.weekendDate >= AppointmentBooked_DateTime and w.weekendDate <= [Date] 
    WHERE AppointmentBooked_DateTime >= @Start_Date  
    and AppointmentBooked_DateTime < @End_Date
