存儲過程NULL值SQL Server

Question

我有一個存儲過程，從視圖中選擇數據並根據條件將其插入tempTable。我想要做的是確保如果有添加日期的NULL值，他們會被排除在外。

Insert into tempIntake(Pop, PlanID, PopFull, ApptDate, 1stAppt, Followup, Rn, UserID) 
select Pop, PlanID, PopFull, InterviewDate, 1stAppt, Followup, rn, @UserID 
from 
    (Select *, row_number() over (partition by PlanID order BY AddedDate ASC) as rn 
    from VInfo) t 
where rn = 1 
and interviewdate >= @fromDate 
and interviewDate <= @toDate 

我該怎麼做？

我基本上是嘗試按早期的ADDEDDATE過濾，但排除可能出現的空日期。

我有這個SP，我也有另一個存儲過程，做ADDEDDATE DESC。但我不知道這是否喜歡我只有一個約會的事實。對於ASC分區，它取出一個空值，對於DESC它取出一個實際日期（只有一個日期）。我希望能夠在這兩個存儲過程中使用該日期（除非有多個日期 - 這是當我希望它抓住最早的日期和最後的日期）

除非我失去了一些東西，一個簡單的地方派生表條款應做的伎倆：

Insert into tempIntake(Pop, PlanID, PopFull, ApptDate, 1stAppt, Followup, Rn, UserID) 
select Pop,PlanID, PopFull,InterviewDate,1stAppt,Followup, rn, @UserID 
from (
    Select *,row_number() over (partition by PlanID order BY AddedDate ASC) as rn 
    from VInfo 
    where AddedDate is not null 
) t 
where rn = 1 
and interviewdate >=@fromDate 
and interviewDate <=@toDate

繼我們在我認爲的意見談話像這是你在找什麼：

Insert into tempIntake(Pop, PlanID, PopFull, ApptDate, 1stAppt, Followup, Rn, UserID) 
select Pop,PlanID, PopFull,InterviewDate,1stAppt,Followup, rn, @UserID 
from (
    Select *,row_number() over (partition by PlanID order BY AddedDate ASC) as rn 
    from VInfo 
    where AddedDate is not null 
) t 
where rn = 1 
and interviewdate >=@fromDate 
and interviewDate <=@toDate 

union 

select Pop,PlanID, PopFull,InterviewDate,'2016-01-01',Followup, rn, @UserID 
from (
    Select *,row_number() over (partition by PlanID order BY AddedDate ASC) as rn 
    from VInfo t1 
    where AddedDate is null 
    and not exists 
    (
     select 1 
     from VInfo t 
     where AddedDate is not null 
     and interviewdate >=@fromDate 
     and interviewDate <=@toDate 
    ) 
) t 
where rn = 1 
and interviewdate >=@fromDate 
and interviewDate <=@toDate
