This query returns 2 rows, but I want to select just one row that has maximum versionDate. How can I select it?
Is this what you want?
SELECT TOP (1) v.DoorNo,v.NewDoorNo, v.GarageName, c.VersionDate, v.OperatorName as Operator, v.OperatorId, c.DeviceId, c.VehicleId, c.ProgramVersionNo,

dbo.CDeviceVersion AS c with(nolock) ON (v.DoorNo = c.DoorNo
or v.NewDoorNo=c.DoorNo)
where v.NewDoorNo='O1211'
ORDER BY c.VersionDate

based on my question above, below is the SQL
SELECT ets_tools.tools_id, ets_borrower.fullname, ets_team.team_name, ets_borrow.time_from,
ets_borrow.time_to, ets_borrow.borrow_id FROM ets_tools
INNER JOIN ets_tools_borrow ON ets_tools.tools_id = ets_tools_borrow.tools_id
INNER JOIN ets_borrow ON ets_borrow.borrow_id = ets_tools_borrow.borrow_id
INNER JOIN ets_borrower ON ets_borrower.badgeid = ets_borrow.badgeid
INNER JOIN ets_team ON ets_team.team_id = ets_borrower.team_id
WHERE ets_tools.borrow_id IS NOT NULL AND ets_borrow.status_id = 1 AND ets_borrow.time_to IS NULL
and the result display like this:
From the image above, we can see that the borrow_id with value 1 display two rows. Now, how to display only one borrow_id for value 1 since its duplicate the same things.
Anyone can help?
Assuming you want to retain the record having the smallest tools_id, you could aggregate by the other columns and take the MIN of tools_id:
SELECT
MIN(ets_tools.tools_id) AS tools_id,
ets_borrower.fullname,
ets_team.team_name,
ets_borrow.time_from,
ets_borrow.time_to,
ets_borrow.borrow_id
FROM ets_tools
INNER JOIN ets_tools_borrow ON ets_tools.tools_id = ets_tools_borrow.tools_id
INNER JOIN ets_borrow ON ets_borrow.borrow_id = ets_tools_borrow.borrow_id
INNER JOIN ets_borrower ON ets_borrower.badgeid = ets_borrow.badgeid
INNER JOIN ets_team ON ets_team.team_id = ets_borrower.team_id
WHERE
ets_tools.borrow_id IS NOT NULL AND
ets_borrow.status_id = 1 AND
ets_borrow.time_to IS NULL
GROUP BY
ets_borrower.fullname,
ets_team.team_name,
ets_borrow.time_from,
ets_borrow.time_to,
ets_borrow.borrow_id;
Try this:
Change the SELECT to SELECT TOP 1 WITH TIES
And at the end add ORDER BY ROW_NUMBER() OVER(PARTITION BY ets_borrow.borrow_id ORDER BY ets_tools.tools_id)
select Id,Prayaseeid, name,Gender,
(select name from tb_Category where id = Category) AS Category,
ideadescription,Domain,ProjectTerms,ProjectStartDate,Amountsanctioned,
(select Amount from tb_innovatorDisbursement where tbid ='TBINO1111A' and
applyingforcycle='1') AS AmountDisbursed,
projectstatus,projectoutcome
from tb_innovator
where tbid='TBINO1111A 'and applyingforcycle='1'
Use TOP to Limit rows to 1,
The Select queries in parenthesis resulting in more than one record
select Id,Prayaseeid, name,Gender,
(select TOP(1) name from tb_Category where id = Category) AS Category,
ideadescription,Domain,ProjectTerms,ProjectStartDate,Amountsanctioned,
(select TOP(1) Amount
from tb_innovatorDisbursement where tbid ='TBINO1111A' and applyingforcycle='1') AS AmountDisbursed,
projectstatus,projectoutcome from tb_innovator
where tbid='TBINO1111A 'and applyingforcycle='1'
You need to test your sub queries for the where clause to make sure the values you are searching do not have multiple records. I would use (Top 1 ) for any column other than the Id column assuming the Id column must be unique as the name suggests.
Update query
select ti.Id,
ti.Prayaseeid,
ti.name,
ti.Gender,
(select TOP(1) name from tb_Category where id = ti.Category) AS Category,
ti.ideadescription,
ti.Domain,
ti.ProjectTerms,
ti.ProjectStartDate,
ti.Amountsanctioned,
tid.Amount AS AmountDisbursed,
ti.projectstatus,
ti.projectoutcome
from tb_innovator ti
INNER JOIN tb_innovatorDisbursement tid ON tid.Tbid = ti.tbid
AND tid.applyingforcycle='1'
where ti.tbid='TBINO1111A 'and ti.applyingforcycle='1'
Perhaps you should use JOIN:
select i.Id, i.Prayaseeid, i.name, i.Gender, c.Category,
i.ideadescription, i.Domain, i.ProjectTerms, i.ProjectStartDate, i.Amountsanctioned,
id.Amount from tb_innovatorDisbursement
i.projectstatus, i.projectoutcome
from tb_innovator i left join
tb_Category c
on i.category = c.id left join
tb_innovatorDisbursement id
on id.tbid = i.dbid and id.applyingforcycle = '1'
where i.tbid = 'TBINO1111A 'and i.applyingforcycle = '1';
Note that all column names are qualified as well, indicating what table they come from.
SELECT [Acc_DocumentNo],[Acc_DocumentDate],[Acc_DocumentType],[Acc_DocumentRef],[Acc_DocumentAmount],
[Acc_CustomerID],[Acc_DebtorGroupID],[Acc_DebtorBranchID],
(SELECT Acc_ManualReferenceNo
FROM Acc_CreditDocuments
WHERE Acc_DocumentNo IN
(SELECT Acc_DocumentRef FROM Acc_CreditDocuments
WHERE Acc_DocumentNo = #DocumentNo)) As [Acc_ManualReferenceNo],
[Acc_Status],[Acc_CreatedBy],[Acc_CreatedAt],[Acc_ModifiedBy],[Acc_ModifiedAt]
FROM Acc_CreditDocuments
WHERE Acc_DocumentNo = #DocumentNo AND
Acc_DocumentRef <> Acc_DocumentNo
In above query, subquery statement for selecting Acc_ManualReferenceNo returns more than one value if it has more than one DocumentNo.
Can I open db cursor to fetch and insert the values one by one? Or is there any other way to do it?
Any help will be much appreciated!
JOIN the table with itself instead, like this:
SELECT
a1.[Acc_DocumentNo],
a1.[Acc_DocumentDate],
a1.[Acc_DocumentType],
a1.[Acc_DocumentRef],
a1.[Acc_DocumentAmount],
a1.[Acc_CustomerID],
a1.[Acc_DebtorGroupID],
a1.[Acc_DebtorBranchID],
a2.Acc_ManualReferenceNo As [Acc_ManualReferenceNo] -- < --
...
FROM Acc_CreditDocuments AS a1
INNER JOIN Acc_CreditDocuments AS a2 ON a1.cc_DocumentRef = a2.Acc_DocumentNo
WHERE Acc_DocumentNo = #DocumentNo
AND a1.Acc_DocumentRef <> a1.Acc_DocumentNo
I have a query:
SELECT A.AHSHMT AS SHIPMENT, A.AHVNAM AS VENDOR_NAME, D.UNITS_SHIPPED, D.ADPON AS PO, B.NUMBER_OF_CASES_ON_TRANSIT, C.NUMBER_OF_CASES_RECEIVED FROM AHASNF00 A
INNER JOIN (SELECT IDSHMT, COUNT(*) AS NUMBER_OF_CASES_ON_TRANSIT FROM IDCASE00 WHERE IDSTAT = '01' GROUP BY IDSHMT) B
ON (A.AHSHMT = B.IDSHMT)
LEFT JOIN (SELECT IDSHMT, (COUNT(*) AS NUMBER_OF_CASES_RECEIVED FROM IDCASE00 WHERE IDSTAT = '10' GROUP BY IDSHMT) C
ON (A.AHSHMT = C.IDSHMT)
INNER JOIN (SELECT ADSHMT, ADPON, SUM(ADUNSH) AS UNITS_SHIPPED FROM ADASNF00 GROUP BY ADSHMT, ADPON) D
ON (A.AHSHMT = D.ADSHMT)
WHERE A.AHSHMT = '540041134';
On the first JOIN statement I have a COUNT(*), on this count sometimes I will get NULL. I need to replace this with a "0-zero", I know think I know how to do it in SQL
ISNULL(COUNT(*), 0)
But this doesn't work for DB2, how can I accomplish this? All your help is really appreciate it.
Wrap a COALESCE around each of the nullable totals in your SELECT list:
SELECT A.AHSHMT AS SHIPMENT,
A.AHVNAM AS VENDOR_NAME,
COALESCE( D.UNITS_SHIPPED, 0 ) AS UNITS_SHIPPED,
D.ADPON AS PO,
COALESCE( B.NUMBER_OF_CASES_ON_TRANSIT, 0 ) AS NUMBER_OF_CASES_ON_TRANSIT,
COALESCE( C.NUMBER_OF_CASES_RECEIVED, 0 ) AS NUMBER_OF_CASES_RECEIVED
FROM ...
The inner joins you're using for expressions B and D mean that you will only receive rows from A that have one or more cases in transit (expression B) and have one or more POs in expression D. Is that the way you want your query to work?
Instead of using ISNULL(COUNT(*), 0),
try using COALESCE(COUNT(*),0)
use IFNULL(COUNT(*), 0) for DB2
I have the following SQL query:
SELECT VehicleRegistrations.ID, VehicleRegistrations.VehicleReg,
VehicleRegistrations.Phone, VehicleType.VehicleTypeDescription,
dt.ID AS 'CostID', dt.IVehHire, dt.FixedCostPerYear, dt.VehicleParts,
dt.MaintenancePerMile, dt.DateEffective
FROM VehicleRegistrations
INNER JOIN VehicleType ON VehicleRegistrations.VehicleType = VehicleType.ID
LEFT OUTER JOIN (SELECT TOP (1) ID, VehicleRegID, DateEffective, IVehHire,
FixedCostPerYear, VehicleParts, MaintenancePerMile
FROM VehicleFixedCosts
WHERE (DateEffective <= GETDATE())
ORDER BY DateEffective DESC) AS dt
ON dt.VehicleRegID = VehicleRegistrations.ID
What I basically want to do is always select the top 1 record from the 'VehicleFixedCosts' table, where the VehicleRegID matches the one in the main query. What is happening here is that it's selecting the top row before the join, so if the vehicle registration of the top row doesn't match the one we're joining to it returns nothing.
Any ideas? I really don't want to have use subselects for each of the columns I need to return
Try this:
SELECT vr.ID, vr.VehicleReg,
vr.Phone, VehicleType.VehicleTypeDescription,
dt.ID AS 'CostID', dt.IVehHire, dt.FixedCostPerYear, dt.VehicleParts,
dt.MaintenancePerMile, dt.DateEffective
FROM VehicleRegistrations vr
INNER JOIN VehicleType ON vr.VehicleType = VehicleType.ID
LEFT OUTER JOIN (
SELECT ID, VehicleRegID, DateEffective, IVehHire, FixedCostPerYear, VehicleParts, MaintenancePerMile
FROM VehicleFixedCosts vfc
JOIN (
select VehicleRegID, max(DateEffective) as DateEffective
from VehicleFixedCosts
where DateEffective <= getdate()
group by VehicleRegID
) t ON vfc.VehicleRegID = t.VehicleRegID and vfc.DateEffective = t.DateEffective
) AS dt
ON dt.VehicleRegID = vr.ID
Subquery underneath dt might need some grouping but without schema (and maybe sample data) it's hard to say which column should be involved in that.
