Question

所以我有这个代码，它可以获取这些列/数据及其所属的表：

StudentName -- ST 
stunum -- ST    
ssn -- ST 
Campus -- CA    
SchoolStatus -- SS  
Program -- AE
AYStart -- FS
AYEnd -- FS 
AYStatus -- PS  
StaffName -- SF 
fastudentayid -- AU 
DateAdded -- AU

这是我的代码

select rtrim(st.lastname) +', '+rtrim(st.FirstName) as StudentName, 
    st.StuNum, 
    st.SSN as SSN, 
    ca.Descrip as Campus, 
    ss.Descrip as SchoolStatus,
    ae.adProgramDescrip as Program, 
    convert(varchar(10),fs.StartDate,101) as AYStart, 
    convert(varchar(10),fs.EndDate,101) as AYEnd, 
    ps.Descrip as AYStatus,
    rtrim(sf.lastname) +', '+rtrim(sf.FirstName) as StaffName,
    fs.faStudentAyID as faStudentAyID,
    convert(varchar(10), MAX(af.DateAdded),101) as DateAdded
from stuTbl (nolock) as ST
join CpsTbl (nolock) as CA
    on ca.CpsID = st.CpsID
join scStatTbl (nolock) as SS
    on ss.ScStatTblID = st.ScStatTblID
join AdEnTbl (nolock) as AE
    on ae.stuTblID = st.stuTblID
join faStAy (nolock) as FS
    on fs.AdEnTblID = ae.AdEnTblID
join FaPStat (nolock) as PS
    on ps.FaPStatID = fs.FaPStatID
join (select RecordID, ColumnName, NewVal, UserID, DateAdded, MAX(DateAdded) as MDA
    from syA_FaPStatTbl
    where ColumnName = 'Package Status'
    and (NewVal = '38' 
    or NewVal = '40'
    or NewVal = '43'
    or NewVal = '67'
    or NewVal = '68')
    and DateAdded between getDate()-90 and getDate()
    group by RecordID, ColumnName, NewVal, UserID, DateAdded) as AF
    on af.RecordID = fs.faStAyID
join StaffTbl (nolock) as SF
    on af.UserID = sf.StaffTblID
where (ps.Descrip = 'Submitted' 
    or ps.Descrip = 'Resubmitted'
    or ps.Descrip = 'Pell Submitted'
    or ps.Descrip = 'Aid Submitted'
    or ps.Descrip = 'Aid Resubmitted')
and af.DateAdded between getDate()-90 and getDate()
Group by st.lastname, st.FirstName, 
    st.StuNum, 
    st.SSN,
    ca.Descrip,
    ss.Descrip, 
    ae.adProgramDescrip,
    fs.StartDate,
    fs.EndDate,
    ps.Descrip,
    sf.lastname, sf.FirstName, 
    fs.faStudentAyID

我得到了我需要的数据，因为我没有复制条目。我的问题是，如果有人改变客户端软件的状态，只要更改在今天的90天之内，它就会将状态切换为“已提交”的两个实例都拉出来。

这是一个示例数据 - 请注意Crytal Ball的记录？有人更新了状态，并于5月11日和6/5/2018再次提交。无论状态如何更新，我都需要最新的记录，无论过去90天发生了多少次，在这种情况下是6/5/2018。

编辑： - 我已经尝试将Top 1放在代码的JOIN（Select）部分，它不会让我拉任何记录。

您需要做的只是使用 row_number（）来获取正确的数据，如下所示

select 
StudentName,StuNum,SSN,Campus,
SchoolStatus,Program,AYStart,AYEnd,AYStatus,
StaffName,faStudentAyID,DateAdded
from
(select *,
    row_number() over( partition by fs.faStudentAyID order by DateAdded) as rn
from
(
    select rtrim(st.lastname) +', '+rtrim(st.FirstName) as StudentName, 
    st.StuNum, 
    st.SSN as SSN, 
    ca.Descrip as Campus, 
    ss.Descrip as SchoolStatus,
    ae.adProgramDescrip as Program, 
    convert(varchar(10),fs.StartDate,101) as AYStart, 
    convert(varchar(10),fs.EndDate,101) as AYEnd, 
    ps.Descrip as AYStatus,
    rtrim(sf.lastname) +', '+rtrim(sf.FirstName) as StaffName,
    fs.faStudentAyID as faStudentAyID,
    convert(varchar(10), MAX(af.DateAdded),101) as DateAdded
from stuTbl (nolock) as ST
join CpsTbl (nolock) as CA
    on ca.CpsID = st.CpsID
join scStatTbl (nolock) as SS
    on ss.ScStatTblID = st.ScStatTblID
join AdEnTbl (nolock) as AE
    on ae.stuTblID = st.stuTblID
join faStAy (nolock) as FS
    on fs.AdEnTblID = ae.AdEnTblID
join FaPStat (nolock) as PS
    on ps.FaPStatID = fs.FaPStatID
join (select RecordID, ColumnName, NewVal, UserID, DateAdded, MAX(DateAdded) as MDA
    from syA_FaPStatTbl
    where ColumnName = 'Package Status'
    and (NewVal = '38' 
    or NewVal = '40'
    or NewVal = '43'
    or NewVal = '67'
    or NewVal = '68')
    and DateAdded between getDate()-90 and getDate()
    group by RecordID, ColumnName, NewVal, UserID, DateAdded) as AF
    on af.RecordID = fs.faStAyID
