I want to include tcon.Inductive_Injection_Hours, tcon.Capacitive_Injection_Hours without applying group by. How can I do that?
SELECT
bp.Serial_Number,
tcon.Serial_Number AS ConverterSerialNumber,
MAX(tcon.Time_Stamp) AS DateStamp,
tcon.Inductive_Injection_Hours,
tcon.Capacitive_Injection_Hours
FROM
dbo.Bypass AS bp
INNER JOIN
dbo.Converter AS c ON bp.Bypass_ID = c.Bypass_ID
INNER JOIN
dbo.Converter_Tel_Data AS tcon ON c.Converter_ID = tcon.Converter_ID
WHERE
(bp.Site_ID = 7)
GROUP BY
bp.Serial_Number, tcon.Serial_Number,
tcon.Inductive_Injection_Hours, tcon.Capacitive_Injection_Hours
ORDER BY
ConverterSerialNumber
I have figured it out.
select [data].Serial_Number,Time_Stamp,Inductive_Injection_Hours,Capacitive_Injection_Hours,b.Serial_Number from Converter_Tel_Data as [data]
inner join dbo.Converter AS c On [data].Converter_ID = c.Converter_ID
inner join dbo.Bypass as b on c.Bypass_ID = b.Bypass_ID
WHERE
(Time_Stamp = (SELECT MAX(Time_Stamp) FROM Converter_Tel_Data WHERE Converter_ID = [data].Converter_ID)) And ([data].Site_ID=7)
ORDER BY [data].Serial_Number
You can use row_number - either in a CTE/derived table or using a trick with TOP 1.
Select Top 1 With Ties
bp.Serial_Number
, tcon.Serial_Number AS ConverterSerialNumber
, tcon.Time_Stamp AS DateStamp
, tcon.Inductive_Injection_Hours
, tcon.Capacitive_Injection_Hours
From dbo.Bypass AS bp
Inner Join dbo.Converter AS c On bp.Bypass_ID = c.Bypass_ID
Inner Join dbo.Converter_Tel_Data AS tcon ON c.Converter_ID = tcon.Converter_ID
Where bp.Site_ID = 7
Order By
row_number() over(Partition By bp.Serial_Number Order By tcon.Time_Stamp desc)
This should return the latest row from the tconn table for each bp.Serial_Number.

I have the above query that is supposed to return rows with unique Rec.[Reg_No]. But joined table TargetDate can have duplicate Rec.[Reg_ID] and if thats the case i get duplicate Rec.[Reg_No] rows in my results.
Table TargetDate has a date time column so i want to eliminate the duplicate Rec.[Reg_No] by selecting 1 row with the latest date value from table TargetDate.
How do modify my Join condition or the query where clause to achive the above?
One way is to use a window function such as ROW_NUMBER() that will generate sequential number based on the specified partition. This generated number can then be used to get the latest row.
SELECT Reg_ID, Reg_No, Case_ID, CaseDeleted, [Status], Signature, [Target], TargetID
FROM
(
SELECT Rec.[Reg_ID]
,Rec.[Reg_No]
,Rec.[Case_ID]
,Det.Deleted AS CaseDeleted
,[Status].[Status]
,Det.[Unit_Submission_Date] AS [Signature]
,TD.TargetDate AS [Target]
,TD.TargetID
,RN = ROW_NUMBER() OVER (PARTITION BY Rec.[Reg_No] ORDER BY TD.TargetID DESC)
FROM [BOI].[dbo].[Regestrations] Rec
LEFT JOIN [dbo].[Reg_Details] Det ON Rec.Case_ID = Det.CaseID
LEFT JOIN [dbo].[lkpStatus] [Status] ON Rec.Status_ID = [Status].StatusID
LEFT JOIN TargetDate TD ON TD.RecommId = Rec.Reg_ID
WHERE (Det.MissionID = 50 AND [Status].[Status] = 1 AND Rec.Deleted = 0 AND Det.Deleted = 0)
) subQuery
WHERE RN = 1
ORDER BY TargetID desc
This query can work correctly if you remove TD.TargetDate from GROUP BY clause and compute what you really need in output - MAX(TD.TargetDate)
But preferable way it to avoid GROUP BY clause at all:
...
FROM [BOI].[dbo].[Regestrations] Rec
LEFT JOIN [dbo].[Reg_Details] Det ON Rec.Case_ID = Det.CaseID
LEFT JOIN [dbo].[lkpStatus] [Status] ON Rec.Status_ID = [Status].StatusID
OUTER APPLY(
SELECT TOP 1 td.TargetDate, td.TargetID
FROM TargetDate TD
WHERE TD.RecommId = Rec.Reg_ID
ORDER BY TD.TargetDate DESC
) td
...
You should first find latest TargetDate for each Reg_ID or RecommId. Then you can use your normal join with TargetDate table just this time with matching both the RecommId and TargetDate.
Try this Query:
SELECT Rec.[Reg_ID]
,Rec.[Reg_No]
,Rec.[Case_ID]
,Det.Deleted AS CaseDeleted
,[Status].[Status]
,Det.[Unit_Submission_Date] AS [Signature]
,TD.TargetDate AS [Target]
,TD.TargetID
FROM [BOI].[dbo].[Regestrations] Rec
LEFT JOIN [dbo].[Reg_Details] Det ON Rec.Case_ID = Det.CaseID
LEFT JOIN [dbo].[lkpStatus] [Status] ON Rec.Status_ID = [Status].StatusID
LEFT JOIN (SELECT RecommId, MAX(TargetDate) MaxTargetDate GROUP BY RecommId) TDWithLatestDate ON TDWithLatestDate.RecommId = Rec.Reg_ID
LEFT OUTER JOIN TargetDate ON TD.RecommId = TDWithLatestDate.RecommId AND TD.TargetDate = TDWithLatestDate.MaxTargetDate
WHERE (Det.MissionID = 50
AND [Status].[Status] = 1
AND Rec.Deleted = 0
AND Det.Deleted = 0
)
GROUP BY Rec.[Reg_ID]
,Rec.[Reg_No]
,Rec.[Case_ID]
,[Status].[Status]
,Det.[Unit_Submission_Date]
,TD.TargetDate
,Det.Deleted
,TD.TargetID
ORDER BY TD.TargetID desc
You can improve this query if you want to avoid tie when there more than one record fighting to be latest.
The attached code is supposed to return the first ORDER_PROC.ORDER_INST for each patient. I'm getting multiple records in some cases.
Any suggestions on a better approach?
Thanks

I have a query returning data for several dates.
I want to return only record with the most recent date in the field SAPOD (the date is in fact CYYMMDD where C=0 before 2000 and 1 after 2000 and I can show this as YYYYMMDD using SAPOD=Case when LEFT(SAPOD,1)=1 then '20' else '19' end + SUBSTRING(cast(sapod as nvarchar(7)),2,7))
here is my query:
SELECT GFCUS, Ne.NEEAN, SCDLE, SAPOD, SATCD,CUS.GFCUN, BGCFN1,
BGCFN2, BGCFN3, SV.SVCSA, SV.SVNA1, SV.SVNA2, SV.SVNA3,
SV.SVNA4, SV.SVNA5, SV.SVPZIP, SV.NONUK
FROM SCPF ACC
INNER JOIN GFPF CUS ON GFCPNC = SCAN
LEFT OUTER JOIN SXPF SEQ ON SXCUS = GFCUS AND SXPRIM = ''
LEFT OUTER JOIN SVPFClean SV ON SVSEQ = SXSEQ
LEFT OUTER JOIN BGPF ON BGCUS = GFCUS AND BGCLC = GFCLC
LEFT OUTER JOIN NEPF NE ON SCAB=NE.NEAB and SCAN=ne.NEAN and SCAS=ne.NEAS
LEFT OUTER JOIN SAPF SA ON SCAB=SAAB and SCAN=SAAN and SCAS=SAAS

scsac='IV' and
scbal = 0 and
scai30<>'Y' and
scai14<>'Y' and
not exists(select * from v5pf where v5and=scan and v5bal<>0))
GROUP BY GFCUS, Ne.NEEAN, SCDLE, SAPOD, SATCD,
CUS.GFCUN, BGCFN1, BGCFN2, BGCFN3, SV.SVCSA,

I am getting results like the below where there are several transactions by a customer, and we only want to show the data of the most recent transaction:
So how can I show just the most recent transaction? Is this a case where I should use an OUTER APPLY or CROSS APPY?
EDIT:
Sorry I should clarify that I need the most recent date for each of the unique records in the field NEEAN which is the Account number
You can use ROW_NUMBER() as follows:
SELECT
ROW_NUMBER() OVER (PARTITION BY Ne.NEEAN ORDER BY SAPOD DESC) AS [Row],
GFCUS, Ne.NEEAN, SCDLE, SAPOD, SATCD,CUS.GFCUN, BGCFN1,
BGCFN2, BGCFN3, SV.SVCSA, SV.SVNA1, SV.SVNA2, SV.SVNA3,
SV.SVNA4, SV.SVNA5, SV.SVPZIP, SV.NONUK
FROM SCPF ACC
INNER JOIN GFPF CUS ON GFCPNC = SCAN
LEFT OUTER JOIN SXPF SEQ ON SXCUS = GFCUS AND SXPRIM = ''
LEFT OUTER JOIN SVPFClean SV ON SVSEQ = SXSEQ
LEFT OUTER JOIN BGPF ON BGCUS = GFCUS AND BGCLC = GFCLC
LEFT OUTER JOIN NEPF NE ON SCAB=NE.NEAB and SCAN=ne.NEAN and SCAS=ne.NEAS
LEFT OUTER JOIN SAPF SA ON SCAB=SAAB and SCAN=SAAN and SCAS=SAAS
WHERE
(SATCD>500 and
scsac='IV' and
scbal = 0 and
scai30<>'Y' and
scai14<>'Y' and
not exists(select * from v5pf where v5and=scan and v5bal<>0)) and
[Row] = 1
GROUP BY GFCUS, Ne.NEEAN, SCDLE, SAPOD, SATCD,
CUS.GFCUN, BGCFN1, BGCFN2, BGCFN3, SV.SVCSA,
SV.SVNA1, SV.SVNA2, SV.SVNA3, SV.SVNA4, SV.SVNA5, SV.SVPZIP, SV.NONUK
ORDER BY MAX(SCAN) ASC
You could encapsulate this within a subquery if you don't want to return the [Row] column.
you can user row_number to get top 1 row per customer
In the where clause need to return values with pos value as 1
sample query
row_number() over ( partition by GFCUS order by SAPOD desc) as pos
I need get the price of lasted QuoteDate.
Right now i have query like these
SELECT dbo.INMT.Material, dbo.INMT.LastVendor, dbo.INMT.AvgCost, dbo.MSQD.Status, dbo.MSQH.QuoteDate, dbo.MSQD.UnitPrice
FROM dbo.INMT INNER JOIN
dbo.MSQD ON dbo.INMT.MatlGroup = dbo.MSQD.MatlGroup AND dbo.INMT.Material = dbo.MSQD.Material INNER JOIN
dbo.MSQH ON dbo.MSQD.MSCo = dbo.MSQH.MSCo AND dbo.MSQD.Quote = dbo.MSQH.Quote
GROUP BY dbo.INMT.Material, dbo.INMT.LastVendor, dbo.INMT.AvgCost, dbo.MSQD.Status, dbo.MSQD.UnitPrice, dbo.MSQH.QuoteDate
ORDER BY dbo.INMT.Material
and get the following result
and how can i run a query just get the highlighted record.i try to do something like where QuoteDate =max......but maybe my grouyping is not correct.
thanks
So, assuming SQL Server 2005+, you can use a CTE and ROW_NUMBER():
;WITH CTE AS
(
SELECT I.Material,
I.LastVendor,
I.AvgCost,
MD.Status,
MH.QuoteDate,
MD.UnitPrice,
RN = ROW_NUMBER() OVER( PARTITION BY I.Material, I.LastVendor,
I.AvgCost, MD.Status,
MD.UnitPrice
ORDER BY MH.QuoteDate DESC)
FROM dbo.INMT I
INNER JOIN dbo.MSQD MD
ON I.MatlGroup = MD.MatlGroup
AND I.Material = MD.Material
INNER JOIN dbo.MSQH MH
ON MD.MSCo = MH.MSCo
AND MD.Quote = MH.Quote
)
SELECT Material,
LastVendor,
AvgCost,
Status,
QuoteDate,
UnitPrice
FROM CTE
WHERE RN = 1
Use HAVING QuoteDate=max... after the order by clause.
I have the following two T-SQL statements that I really need to combine:
SELECT Aircraft.Id AS AircraftID, AircraftManufacturers.Name, AircraftModels.ModelName,
Aircraft.ModelSuffix, Aircraft.ImageFileName, Aircraft.Year, Aircraft.SerialNo,

FROM (((Aircraft
INNER JOIN Advertisers ON Aircraft.AdvertiserId = Advertisers.Id)
INNER JOIN AircraftModels ON Aircraft.AircraftModelId = AircraftModels.Id)
INNER JOIN AircraftManufacturers ON AircraftModels.ManufacturerId = AircraftManufacturers.Id)

WHERE (Aircraft.IsActive=1 AND Advertisers.IsActive=1 AND (Aircraft.EndDate>=#Date OR Aircraft.EndDate Is Null) AND Locations.DescriptionForSite LIKE #Location)
OR (Advertisers.IsActive=1 AND Aircraft.IsSold=1 AND Aircraft.SoldDate>=#Date2 AND Locations.DescriptionForSite LIKE #Location)
ORDER BY Advertisers.IsPremiumAdvertiser ASC, Aircraft.DateAdded DESC, Aircraft.ListPosition DESC,
Aircraft.LastUpdateDate, AircraftManufacturers.Name, AircraftModels.ModelName, Aircraft.ModelSuffix,
Aircraft.Id DESC
and
SELECT TOP (1) dbo.Addresses.Email, dbo.Addresses.Contact, dbo.Addresses.Telephone1
FROM dbo.AdvertiserAddressLink
INNER JOIN dbo.Addresses ON dbo.AdvertiserAddressLink.AddressId = dbo.Addresses.Id
WHERE (dbo.AdvertiserAddressLink.AdvertiserId = 'AdvertisersID') <--see above
AND (dbo.Addresses.AddressType = 1 OR dbo.Addresses.AddressType = 0)
ORDER BY dbo.Addresses.AddressType DESC, dbo.Addresses.Sequence
It looks like you want to do TOP 1 in the second query based on a correlated parameter from the first?
You can use APPLY for this.
A simple example.
SELECT t.name, ca.name
FROM sys.tables t
CROSS APPLY (SELECT TOP 1 *
FROM sys.columns c
WHERE c.object_id=t.object_id
ORDER BY name) ca
