Select only oldest unique records - sql

Question

The below code should
Grab multiple values from multiple tables across 2 databases
but as I attempted to implement
T-SQL select rows by oldest date and unique category solution to an issue I encountered an error where the final line of my code would say "Incorrect syntax near ')'."
--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)
UPDATE: So the bracket near "RN" is open, but if I try to close it the rest of the statement is not understood, anyone know why?

The end of your sql should be：
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
