Question

以下代码应该从2个数据库中的多个表中获取多个值但是当我试图实施时 T-SQL select rows by oldest date and unique category问题的解决方案我遇到了一个错误，我的代码的最后一行会说＆＃34;＆＃39;的错误语法＆＃39;。＆＃39;

--Create Table #tmp2(FK_clientids varchar(50))
--Create table #tmp (phonenums varchar(50))
Delete from #tmp2
Delete from #tmp
Use Database2
INSERT INTO #tmp2
SELECT fk_clientid
FROM DM_ClientApplicants
where DM_ClientApplicants.FK_ApplicationID in (39155)
Use Database2
INSERT INTO #tmp
Select phonenum2 from DM_PhoneNumbers
where FK_ApplicationID in 
(
   Select FK_clientIDs from #tmp2
)
INSERT INTO #tmp
Select PhoneNum1 from DM_PhoneNumbers
where FK_ApplicationID in 
(
   Select FK_clientIDs from #tmp2
)
INSERT INTO #tmp
Select PhoneNum2 from DM_PhoneNumbers
where FK_ApplicationID in 
(
   Select FK_clientIDs from #tmp2
)

INSERT INTO #tmp
Select PhoneNum3 from DM_PhoneNumbers
where FK_ApplicationID in 
(
   Select FK_clientIDs from #tmp2
)
INSERT INTO #tmp
Select Partnerphonehome from DM_PhoneNumbers
where FK_ApplicationID in 
(
   Select FK_clientIDs from #tmp2
)
INSERT INTO #tmp
Select Partnerphonemobile from DM_PhoneNumbers
where FK_ApplicationID in 
(
   Select FK_clientIDs from #tmp2
)
INSERT INTO #tmp
Select Partnerphonework from DM_PhoneNumbers
where FK_ApplicationID in 
(
   Select FK_clientIDs from #tmp2
)
Use Database1
Select PhoneNum,sourcetable,c.FK_ApplicationID,SolRef,DT.Subject,dt.CreatedDate 
from (select PhoneNum,sourcetable,c.FK_ApplicationID,SolRef,DT.Subject,dt.CreatedDate,
             row_number() over(partition by OrderNO order by dt.CreatedDate desc) rn 
      from Dial D
      join Database2.dbo.DM_PhoneNumbers P on PhoneNum collate Latin1_General_CI_AS = PhoneNum1
      join Database2.dbo.DM_ClientApplicants C on P.FK_ApplicationID = C.FK_ClientID
      join Database2.dbo.DM_Sol S on C.FK_ApplicationID = S.FK_ApplicationID
      join Database2.dbo.DM_ApplicationDetails AD on AD.FK_ApplicationID = S.FK_ApplicationID
      join Database2.dbo.Tasks DT on DT.FK_ApplicationID = S.FK_ApplicationID
where PhoneNum in
(Select phonenums from #tmp)

更新：所以支架靠近＆＃34; RN＆＃34;是开放的，但如果我试图关闭它，其余的陈述不明白，任何人都知道为什么？

你的SQL的结尾应该是：

Use Database1
Select PhoneNum,sourcetable,FK_ApplicationID,SolRef,Subject,CreatedDate 
from 
(
    select PhoneNum,sourcetable,c.FK_ApplicationID,SolRef,DT.Subject,dt.CreatedDate
    ,row_number() over(partition by OrderNO order by dt.CreatedDate desc) rn 
    from Dial D
    join Database2.dbo.DM_PhoneNumbers P on PhoneNum collate Latin1_General_CI_AS = PhoneNum1
    join Database2.dbo.DM_ClientApplicants C on P.FK_ApplicationID = C.FK_ClientID
    join Database2.dbo.DM_Sol S on C.FK_ApplicationID = S.FK_ApplicationID
    join Database2.dbo.DM_ApplicationDetails AD on AD.FK_ApplicationID = S.FK_ApplicationID
    join Database2.dbo.Tasks DT on DT.FK_ApplicationID = S.FK_ApplicationID
    where PhoneNum in
    (
        Select phonenums from #tmp
    )
)a -- add
