I require some help with my very shaky sql skills.
Say I have the following select statement:
SELECT DISTINCT
p.ProjectId,
p.Title,
i.Name,
p.StartDate,
p.EndDate,
ped.ProjectEthicsDocumentId,
st.Description AS StatusText
FROM
dbo.Project p
inner join dbo.WorkflowHistory w ON p.ProjectId = w.ProjectId
left join dbo.ProjectInstitution pi ON pi.ProjectId = p.ProjectId
left join dbo.Institution i ON i.InstitutionId = pi.InstitutionId
left join dbo.ProjectEthicsDocument ped on p.ProjectId = ped.ProjectId
left join dbo.Status st ON p.StatusId = st.StatusId
This will return all the projects and other relevant details from the relevant tables. Now, say I have 2 institutions for 'Project A'. This statement will return 2 rows for 'Project A', one for each institution. How do I set it so that it only returns the first row of each project it finds? I want one instance of every project with say the first institution found.
The easiest way is probably with the row_number() function:
select *
from (SELECT DISTINCT p.ProjectId, p.Title, i.Name, p.StartDate,p.EndDate,
ped.ProjectEthicsDocumentId, st.Description AS StatusText,
row_number() over (partition by p.ProjectId order by i.InstitutionId) as seqnum
FROM dbo.Project p
inner join dbo.WorkflowHistory w ON p.ProjectId = w.ProjectId
left join dbo.ProjectInstitution pi ON pi.ProjectId = p.ProjectId
left join dbo.Institution i ON i.InstitutionId = pi.InstitutionId
left join dbo.ProjectEthicsDocument ped on p.ProjectId = ped.ProjectId
left join dbo.Status st ON p.StatusId = st.StatusId
) p
where seqnum = 1;
You can move selecting institution name to a subquery. This way you it doesn't affect how other tables are joined.
SELECT DISTINCT
p.ProjectId,
p.Title,
(SELECT TOP 1 i.Name FROM dbo.Institution i
INNER JOIN dbo.ProjectInstitution pi ON i.InstitutionId = pi.InstitutionId
WHERE pi.ProjectId = p.ProjectId) AS Name,
p.StartDate,
p.EndDate,
ped.ProjectEthicsDocumentId,
st.Description AS StatusText
FROM
dbo.Project p
inner join dbo.WorkflowHistory w ON p.ProjectId = w.ProjectId
left join dbo.ProjectEthicsDocument ped on p.ProjectId = ped.ProjectId
left join dbo.Status st ON p.StatusId = st.StatusId
you could use
;with cte as
(
<your select statement> `,`
Row_number() over(partition by <column that has 2 records> order by ProjectId) as rn
)
--then do this
select * from cte where rn=1

I have the following SQL query and need to know the count of companyid as I can see repeating data. How do I find the count of it. Following is the query
SELECT a.companyId 'companyId'
, i.orgDebtType 'orgDebtType'
, d.ratingTypeName 'ratingTypeName'
, c.currentRatingSymbol 'currentRatingSymbol'
, c.ratingStatusIndicator 'ratingStatusIndicator'
, g.qualifierValue 'qualifierValue'
, c.ratingdate 'ratingDate'
, h.value 'outlook'
FROM ciqRatingEntity a
JOIN ciqcompany com
on com.companyId = a.companyId
JOIN ciqratingobjectdetail b ON a.entitySymbolValue = b.objectSymbolValue
JOIN ciqRatingData c ON b.ratingObjectKey = c.ratingObjectKey
JOIN ciqRatingType d ON b.ratingTypeId = d.ratingTypeId
JOIN ciqRatingOrgDebtType i ON i.orgDebtTypeId=b.orgDebtTypeId
JOIN ciqRatingEntityData red ON red.entitySymbolValue=a.entitySymbolValue
AND red.ratingDataItemId='1' ---CoName
LEFT JOIN ciqRatingDataToQualifier f ON f.ratingDataId = c.ratingDataId
LEFT JOIN ciqRatingQualifiervalueType g ON g.qualifiervalueid = f.qualifierValueId
LEFT JOIN ciqRatingValueType h ON h.ratingValueId = c.outlookValueId
WHERE 1=1
AND b.ratingTypeId IN ( '130', '131', '126', '254' )
-- and a.companyId = #companyId
AND a.companyId IN
(SELECT distinct TOP 2000000
c.companyId
FROM ciqCompany c
inner join ciqCompanyStatusType cst on cst.companystatustypeid = c.companystatustypeid
inner join ciqCompanyType ct on ct.companyTypeId = c.companyTypeId
inner join refReportingTemplateType rep on rep.templateTypeId = c.reportingtemplateTypeId
inner join refCountryGeo rcg on c.countryId = rcg.countryId
inner join refState rs on rs.stateId = c.stateId
inner join ciqSimpleIndustry sc on sc.simpleIndustryId = c.simpleIndustryId
ORDER BY companyid desc)
ORDER BY companyId DESC, c.ratingdate, b.ratingTypeId, c.ratingStatusIndicator
This will list where there are duplicate companyID's
SELECT companyId, count(*) as Recs
FROM ciqCompany
GROUP BY ciqCompany
HAVING count(*) > 1
I understand that you wish to add a column to the query with the count of each companyId, you can use COUNT() OVER():
select count(a.companyId) over (partition by a.companyId) as companyCount,
<rest of the columns>
from ciqRatingEntity a
join <rest of the query>
This would return in each row the count of the companyId of that row without grouping the results.
I have couple of tables which stores amount and I want to group by and get sum - reason for the mutiple tables are nhibernate descriminators.
I am using Union all and works but query is very big.
I am using following query
SELECT CustomerAccountNumber,
vc.CustomerName,
SUM(PermAmount) AS PermAmount,
SUM(FreetextAmount) AS FreetextAmount,
(SUM(PermAmount) + SUM(FreetextAmount)) AS TotalAmountByCustomer
FROM
(
SELECT pp.CustomerAccountNumber,
pl.Amount AS PermAmount,
0 AS FreetextAmount
FROM dbo.PermanentPlacementTransactionLine pl
INNER JOIN dbo.TransactionLine tl ON pl.TransactionLineId = tl.Id
INNER JOIN dbo.PermanentPlacement pp ON pl.PermanentPlacementId = pp.Id
WHERE tl.CurrentStatus = 1
GROUP BY pp.CustomerAccountNumber,
pl.Amount,
tl.Id
UNION ALL
SELECT ft.CustomerAccountNumber,
0 AS PermAmount,
ft.Amount AS FreetextAmount
FROM dbo.FreeTextTransactionLine fttl
INNER JOIN dbo.TransactionLine tl ON fttl.TransactionLineId = tl.Id
INNER JOIN dbo.[FreeText] ft ON fttl.FreeTextId = ft.Id
WHERE tl.CurrentStatus = 1
GROUP BY ft.CustomerAccountNumber,
ft.Amount,
tl.Id
) WIPSummary
INNER JOIN dbo.vw_Customer vc ON WIPSummary.CustomerAccountNumber = vc.CustomerAccount
GROUP BY CustomerAccountNumber,
vc.CustomerName;
is there any elegant way of displaying amount in separate columns ?
I can use partition by if it was same table and want to display row by row.
Try these query, is easy to understand and probably faster than yours.
I assume that the values are unique in your view
WITH cte_a
AS (SELECT pp.customeraccountnumber
,Sum(pl.amount) AS PermAmount
,0 AS FreetextAmount
FROM dbo.permanentplacementtransactionline pl
INNER JOIN dbo.transactionline tl
ON pl.transactionlineid = tl.id
INNER JOIN dbo.permanentplacement pp
ON pl.permanentplacementid = pp.id
WHERE tl.currentstatus = 1
GROUP BY pp.customeraccountnumber),
cte_b
AS (SELECT ft.customeraccountnumber
,0 AS PermAmount
,Sum(ft.amount) AS FreetextAmount
FROM dbo.freetexttransactionline fttl
INNER JOIN dbo.transactionline tl
ON fttl.transactionlineid = tl.id
INNER JOIN dbo.[freetext] ft
ON fttl.freetextid = ft.id
WHERE tl.currentstatus = 1
GROUP BY ft.customeraccountnumber)
SELECT vc.customeraccountnumber
,vc.customername
,Isnull(A.permamount, 0) AS PermAmount
,Isnull(B.freetextamount, 0) AS FreetextAmount
,Isnull(A.permamount, 0)
+ Isnull(B.freetextamount, 0) AS TotalAmountByCustomer
FROM dbo.vw_customer vc
LEFT JOIN cte_a a
ON vc.customeraccount = A.customeraccountnumber
LEFT JOIN cte_b b
ON vc.customeraccount = A.customeraccountnumber
if no table structures and sample data, that is the best I can do to help you.
Would like to take the following Query and alter it so that it brings back ONLY records where each patient (based on MRN) has BOTH ProcedureCodeList IN ('115-1','117-1','311-1') AND ProcedureCodeList = '119-103'
SELECT P.SiteID, O.ProcedureCodeList, P.MRN, PINFO.LastName, PINFO.FirstName, PINFO.[State] AS Species, PINFO.City AS Breed, O.ProcedureDescList, RF.FieldName, RF.FieldValue, R.ContentText
, R.LastSignDate
FROM ReportFinding RF
INNER JOIN Report R
ON RF.ReportID = R.ReportID
INNER JOIN [Order] O
ON R.ReportID = O.ReportID
INNER JOIN Visit V
ON O.VisitID = V.VisitID
INNER JOIN Patient P
ON P.PatientID = V.PatientID
INNER JOIN PersonalInfo PINFO
ON P.PersonalInfoID = PINFO.PersonalInfoID
WHERE
O.ProcedureCodeList IN ('115-1','117-1','119-103')
ORDER BY R.LastSignDate DESC
There are a couple of ways to solve this. One way is to create two subqueries and join them on the MRN.
SELECT a.SiteID, a.ProcedureCodeList, a.MRN, a.LastName, a.FirstName, a.Species, a.Breed, a.ProcedureDescList, a.FieldName, a.FieldValue, a.ContentText, a.LastSignDate
FROM
(SELECT P.SiteID, O.ProcedureCodeList, P.MRN, PINFO.LastName, PINFO.FirstName, PINFO.[State] AS Species, PINFO.City AS Breed, O.ProcedureDescList, RF.FieldName, RF.FieldValue, R.ContentText, R.LastSignDate
FROM ReportFinding RF
INNER JOIN Report R ON RF.ReportID = R.ReportID
INNER JOIN [Order] O ON R.ReportID = O.ReportID
INNER JOIN Visit V ON O.VisitID = V.VisitID
INNER JOIN Patient P ON P.PatientID = V.PatientID
INNER JOIN PersonalInfo PINFO ON P.PersonalInfoID = PINFO.PersonalInfoID
WHERE O.ProcedureCodeList IN ('115-1','117-1','119-103')) as a
JOIN
(SELECT P.MRN
FROM [Order]
INNER JOIN Visit V ON O.VisitID = V.VisitID
INNER JOIN Patient P ON P.PatientID = V.PatientID
WHERE O.ProcedureCodeList = '119-103') as b ON a.MRN = b.MRN
ORDER BY a.LastSignDate
The PersonalInfo table is not needed in the second query. I don't think ReportFinding and Report are either, based on your JOINs. It depends on what these tables are actually doing.
Another way starts with the original query and adds the following to the WHERE clause (before the ORDER BY):
AND P.MRN IN
(SELECT P.MRN
FROM [Order]
INNER JOIN Visit V ON O.VisitID = V.VisitID
INNER JOIN Patient P ON P.PatientID = V.PatientID
WHERE O.ProcedureCodeList = '119-103')
I would look at the execution plans of both solutions to know which is the better one in this case.
I'm fetching some data from our database in MSSQL. Out of this data I want to determine who created the client entry and who took the first payment from this client.
There can be many payment entries for a client on a single booking/enquiry and at the moment, my query shows results for each payment. How can I limit the output to only show the first payment entry?
My query:
SELECT
c.FirstName,
c.LastName,
c.PostalCode,
o.OriginOfEnquiry,
s.SuperOriginName,
c.DateOfCreation,
DATEDIFF(day, c.DateOfCreation, p.DateOfCreation) AS DaysToPayment,
pc.PackageName,
CONCAT(u.FirstName, ' ', u.LastName) AS CreateUser,
(SELECT CONCAT(u.FirstName, ' ', u.LastName)
WHERE u.UserID = p.UserID ) AS PaymentUser
FROM tblBookings b
INNER JOIN tblPayments p
ON b.BookingID = p.BookingID
INNER JOIN tblEnquiries e
ON e.EnquiryID = b.EnquiryID
INNER JOIN tblCustomers c
ON c.CustomerID = e.CustomerID
INNER JOIN tblOrigins o
ON o.OriginID = e.OriginID
INNER JOIN tblSuperOrigins s
ON s.SuperOriginID = o.SuperOriginID
INNER JOIN tblBookingPackages bp
ON bp.bookingID = p.BookingID
INNER JOIN tblPackages pc
ON pc.PackageID = bp.packageID
INNER JOIN tblUsers u
ON u.UserID = c.UserID
WHERE c.DateOfCreation >= '2016-06-01' AND c.DateOfCreation < '2016-06-30'
AND p.PaymentStatusID IN (1,2)
AND e.CustomerID = c.CustomerID
AND p.DeleteMark != 1
AND c.DeleteMark != 1
AND b.DeleteMark != 1
;
I tried adding a "TOP 1" to the nested select statement for PaymentUser, but it made no difference.
you can use cross apply with top 1:
FROM tblBookings b
cross apply
(select top 1 * from tblPayments p where b.BookingID = p.BookingID) as p
Instead of table tblPayments specify sub-query like this:
(SELECT TOP 1 BookingID, UserID, DateOfCreation
FROM tblPayments
WHERE DeleteMark != 1
AND PaymentStatusID IN (1,2)
ORDER BY DateOfCreation) as p
I'm assuming that tblPayments has a primary key column ID. If it is true, you can use this statment:
FROM tblBookings b
INNER JOIN tblPayments p ON p.ID = (
SELECT TOP 1 ID
FROM tblPayments
WHERE BookingID = b.BookingID
AND DeleteMark != 1
AND PaymentStatusID IN (1,2)
ORDER BY DateOfCreation)
I dont know how to rewrite the the query in order to avoid records with ISPRIMARY = 0. In other words the values allowed must be ISPRIMARY = 1 and ISPRIMARY = NULL.
The query is the next:
select
S.assetnum, S.description, S.serialnum,
S.epp_codactfij, S.location, L.description,
S.EPP_NUMCONTRATO, S.PURCHASEPRICE, U.personid, U.isprimary
from maximo.asset S
left join maximo.locations L on S.location=L.location
left join maximo.assetusercust U on S.assetnum=U.assetnum
where
S.siteid ='TI'
order by S.assetnum
Try adding the following line to the WHERE clause:
select
S.assetnum, S.description, S.serialnum, S.epp_codactfij, S.location, L.description, S.EPP_NUMCONTRATO, S.PURCHASEPRICE, U.personid, U.isprimary
from maximo.asset S
left join maximo.locations L on S.location=L.location
left join maximo.assetusercust U on S.assetnum=U.assetnum
where
S.siteid ='TI'
-- add this line
AND (U.isprimary = 1 OR U.isprimary IS NULL)
order by S.assetnum
select
S.assetnum, S.description, S.serialnum, S.epp_codactfij,
S.location, L.description, S.EPP_NUMCONTRATO,
S.PURCHASEPRICE, U.personid, U.isprimary
from maximo.asset S
left join maximo.locations L on S.location=L.location
left join maximo.assetusercust U on S.assetnum=U.assetnum
WHERE S.siteid ='TI' AND (U.isprimary = 1 OR U.isprimary IS NULL)
order by S.assetnum;
or:
select
S.assetnum, S.description, S.serialnum, S.epp_codactfij,
S.location, L.description, S.EPP_NUMCONTRATO,
S.PURCHASEPRICE, U.personid, U.isprimary
from maximo.asset S
left join maximo.locations L on S.location=L.location
left join maximo.assetusercust U on S.assetnum=U.assetnum
WHERE S.siteid ='TI' AND (U.isprimary <> 0 OR U.isprimary IS NULL)
order by S.assetnum;
