SQL Syntax with Left Join with a Subquery?
Can this be done (Left Join on a sub select query with a where? The Bold is stating that Multi-part identifier cannot be bound..Not sure how to re-write this to get the same results, other than below in my "Non-efficient way"
select R.URICode, briefdescription,
BillCode, model, ManName, SERIALNUMBER,HOMELOCATION,
from NewInventory R
left outer join
(Select top 1 Scan_Date, Current_Location, Filepath1 as JobNumber, UPCCode from Scans e where e.upccode = R.URICode order by Scan_Date desc ) G1 on R.URICODE = G1.UPCCode
where R.URICode <='30126'
order by R.URICode asc
Non-Efficient Way:
select b.URICode, briefdescription, BillCode, model, ManName, SERIALNUMBER,HOMELOCATION,
(select top 1 Scan_Date from Scans e where upccode = b.uricode order by Scan_Date desc)as Last_Scan_Date,
(select top 1 Current_Location from Scans e where upccode = b.uricode order by Scan_Date desc)as Current_Location,
(select top 1 FilePath1 as JobNumber from Scans e where upccode = b.uricode order by Scan_Date desc)as JobNumber
from NewInventory b
left join urijobs.dbo.jobs on (select top 1 FilePath1 as JobNumber from Scans e where upccode = b.uricode order by Scan_Date desc) = urijobs.dbo.jobs.Job_Numbe
left join urijobs.dbo.Job_Status on urijobs.dbo.Job_Status.Sta
where b.URICode <='30126'
order by b.URICode asc

order by R.URICode asc
Non-Efficient Way:

it's redundant. The join is essentially you're where.
But there's also no need for the subquery:

order by e.Scan_Date desc, R.URICode
Sorry, I might add in that The Scans table contains multiple scans that day for column URICOde, and I need the latest scan in the scan_Date for that day to be the selected.
;With CTE
As
(
Select Rank() Over(Partition by G.UPCCode order By e.Scan_Date) As rnk
, R.Current_Location
, e.Filepath1 as JobNumber
, R.URICode
, e.Scan_Date
, e.JobNumber
from NewInventory R left join Scans e
On e.upccode = R.URICode
where R.URICode <='30126')
Select R.Current_Location
, e.Filepath1 as JobNumber
, R.URICode
, e.Scan_Date
, e.JobNumber
From CTE
where rnk = 1
Order by CTE.Scan_Date desc, CTE.URICode
I have include just a few fields. After this works, then you can add the remaining fields you want.
