I trying to make a query to obtain the last date time when a records repeat.
select * from OCCONTROLMERCADERIA om
join OCCONTROLMERCADERIALINEAS oml on om.occontrolid=oml.occontrolid
where om.OCControlNroId=5519337
This return this:
Result Query 1
The query that i want should return the register are in the blue box.
I have this query that found (without the join):
with
p as (select * from OCCONTROLMERCADERIA om where om.OCControlNroId=5519337),
p_rnk as (
select *, row_number() over (partition by OCControlNroId order by OCControlFecha desc) as rn
from p
)
select * from p_rnk where rn = 1 order by OCControlNroId;
This return this:
Result Query 2
That its ok, if see the box blue in the first image, the last date corresponds to the record id 13756.
But I need that the query return the 3 records that corresponds to id 13756, and not only one, so i trying to apply the join.
with
p as (select * from OCCONTROLMERCADERIA om
join OCCONTROLMERCADERIALINEAS oml on om.occontrolid=oml.occontrolid
where om.OCControlNroId=5519337),
p_rnk as (
select *, row_number() over (partition by OCControlNroId order by OCControlFecha desc) as rn
from p
)
select * from p_rnk where rn = 1 order by OCControlNroId;
But this return:
The column 'OCControlId' was specified multiple times for 'p'.
I´m trying this (select om.*):
with
p as (select om.* from OCCONTROLMERCADERIA om
join OCCONTROLMERCADERIALINEAS oml on om.occontrolid=oml.occontrolid
where om.OCControlNroId=5519337),
p_rnk as (
select *, row_number() over (partition by OCControlNroId order by OCControlFecha desc) as rn
from p
)
select * from p_rnk where rn = 1 order by OCControlNroId;
And the error disappears but only return one records, no the three. Which could the problem ?
Thanks for your help!

I need to select the data of all my customers with the records displayed in the image. But I need to get the most recent record only, for example I need to get the order # E987 for John and E888 for Adam. As you can see from the example, when I do the select statement, I get all the order records.
You don't mention the specific database, so I'll answer with a generic solution.
You can do:
select *
from (
select t.*,
row_number() over(partition by name order by order_date desc) as rn
from t
) x
where rn = 1
You can use analytical function row_number.
Select * from
(Select t.*,
Row_number() over (partition by customer_id order by order_date desc) as rn
From your_table t) t
Where rn = 1
Or you can use not exists as follows:
Select *
From yoir_table t
Where not exists
(Select 1 from your_table tt
Where t.customer_id = tt.custome_id
And tt.order_date > t.order_date)
You can do it with a subquery that finds the last order date.
SELECT t.*
FROM yoir_table t
JOIN (SELECT tt.custome_id,
MAX(tt.order_date) MaxOrderDate
FROM yoir_table tt
GROUP BY tt.custome_id) AS tt
ON t.custome_id = tt.custome_id
AND t.order_date = tt.MaxOrderDate
I have table that looks like the following
I have to select every second record per PatientID that would give the following result (my last query returns this result)
I then have to select the record with the oldest date which would be the following (this is the end result I want)
What I have done so far: I have a CTE that gets all the data I need
WITH cte
AS
(
SELECT visit.PatientTreatmentVisitID, mat.PatientMatchID,pat.PatientID,visit.RegimenDate AS VisitDate,
ROW_NUMBER() OVER(PARTITION BY mat.PatientMatchID, pat.PatientID ORDER BY visit.VisitDate ASC) AS RowNumber
FROM tblPatient pat INNER JOIN tblPatientMatch mat ON mat.PatientID = pat.PatientID
LEFT JOIN tblPatientTreatmentVisit visit ON visit.PatientID = pat.PatientID
)
I then write a query against the CTE but so far I can only return the second row for each patientID
SELECT *
FROM
(
SELECT PatientTreatmentVisitID,PatientMatchID,PatientID, VisitDate, RowNumber FROM cte
) as X
WHERE RowNumber = 2
How do I return the record with the oldest date only? Is there perhaps a MIN() function that I could be including somewhere?
If I follow you correctly, you can just order your existing resultset and retain the top row only.
In standard SQL, you would write this using a FETCH clause:
SELECT *
FROM (
SELECT
visit.PatientTreatmentVisitID,
mat.PatientMatchID,
pat.PatientID,
visit.RegimenDate AS VisitDate,
ROW_NUMBER() OVER(PARTITION BY mat.PatientMatchID, pat.PatientID ORDER BY visit.VisitDate ASC) AS rn
FROM tblPatient pat
INNER JOIN tblPatientMatch mat ON mat.PatientID = pat.PatientID
LEFT JOIN tblPatientTreatmentVisit visit ON visit.PatientID = pat.PatientID
) t
WHERE rn = 2
ORDER BY VisitDate
OFFSET 0 ROWS FETCH FIRST 1 ROW ONLY
This syntax is supported in Postgres, Oracle, SQL Server (and possibly other databases).
If you need to get oldest date from all selected dates (every second row for each patient ID) then you can try window function Min:
SELECT * FROM
(
SELECT *, MIN(VisitDate) OVER (Order By VisitDate) MinDate
FROM
(
SELECT PatientTreatmentVisitID,PatientMatchID,PatientID, VisitDate,
RowNumber FROM cte
) as X
WHERE RowNumber = 2
) Y
WHERE VisitDate=MinDate
Or you can use SELECT TOP statement. The SELECT TOP clause allows you to limit the number of rows returned in a query result set:
SELECT TOP 1 PatientTreatmentVisitID,PatientMatchID,PatientID, VisitDate FROM
(
SELECT *
FROM
(
SELECT PatientTreatmentVisitID,PatientMatchID,PatientID, VisitDate,
RowNumber FROM cte
) as X
WHERE RowNumber = 2
) Y
ORDER BY VisitDate
For simplicity add order desc on date column and use TOP to get the first row only
SELECT TOP 1 *
FROM
(
SELECT PatientTreatmentVisitID,PatientMatchID,PatientID, VisitDate, RowNumber FROM cte
) as X
WHERE RowNumber = 2
order by VisitDate desc
This query gives me invalid identifier error, and i know it is because subquery will only be able to access data that is one layer higher.
select *
from t2_callerid_plan cp
where cp.subsrefnum in (
select *
from (
select vsap.subsrefnum
from prv_internet_responses_vsap vsap
where vsap.subsrefnum = cp.subsrefnum
order by vsap.id desc
)
where rownum = 1
);
Now, i was wandering if there is way i can create query that would be able to return only the newest row while using the data from query in subquery?
You can use ROW_NUMBER() :
SELECT * FROM (
SELECT cp.*,
ROW_NUMBER() OVER(PARTITION BY cp.subsrefnum ORDER BY vsap.id desc) as rnk
from t2_callerid_plan cp
JOIN prv_internet_responses_vsap vsap
ON vsap.subsrefnum = cp.subsrefnum) p
WHERE p.rnk = 1
you can try this:
select *
from t2_callerid_plan cp
inner join
(
select vsap.subsrefnum,ROW_NUMBER() OVER (PARTITION BY subsrefnum ORDER BY vsap.id desc) rn
from prv_internet_responses_vsap vsap
)vsap
on vsap.subsrefnum = cp.subsrefnum and vsap.rn=1
I have two table in sql. First one the patient list, second one is their report. all patient's reports are in the report, just with id we can join them. Each patient has some reports (Maybe all the fields of a record is not filled). Now I want to make a report that get the last report of each patient but if some field are empty in the last record of that patient I should fill it with last filled record of that patients records. I have date in the table of reports.
I want to do it for all patients. Here I will add a pic for one patient as an example
In the example above, I want just highlighted ones for this patient in the report.
I have write this query but it give even when a filed in the last record is null while it has data in previous records.

ORDER BY patient.bartar_id DESC ;

Final Report What I want
this is a sample,
in your case you have to get the value of each column in a subquery (either in the join statement, or in the main select statement
example:
inner join (
select distinct bartar_patientname
,(select top 1 bartar_pastePerMonth from [Bartar_MSCRM].[dbo].[Filteredbartar_callcenterreport] c2 where c2.bartar_patientname = cte.bartar_patientname and c2.bartar_pastePerMonth is not null order by c2.bartar_date desc) as bartar_date
,(select top 1 bartar_acc from [Bartar_MSCRM].[dbo].[Filteredbartar_callcenterreport] c2 where c2.bartar_patientname = cte.bartar_patientname and c2.bartar_acc is not null order by c2.bartar_date desc) as bartar_acc
,(select top 1 bartar_insuranceinfo from [Bartar_MSCRM].[dbo].[Filteredbartar_callcenterreport] c2 where c2.bartar_patientname = cte.bartar_patientname and c2.bartar_insuranceinfo is not null order by c2.bartar_date desc) as bartar_insuranceinfo
,(select top 1 bartar_brand from [Bartar_MSCRM].[dbo].[Filteredbartar_callcenterreport] c2 where c2.bartar_patientname = cte.bartar_patientname and c2.bartar_brand is not null order by c2.bartar_date desc) as bartar_brand
from [Bartar_MSCRM].[dbo].[Filteredbartar_callcenterreport] cte
) r
Again, this is a sample of the solution.
Your script is fine as it looks, so I'll just place that on a temporary table for now, and do a per sequence query and filter it by "OR" afterwards.
Please try the script below.

INNER JOIN
Production.tblProductTemplateHdr ON tblProductTemplateHdr.product_Temp_ID = tblProductProcessHdr.product_Temp_ID
I want the row with maximum sl_No in each product_Id without using a subquery, this the result obtained by running this query want to apply filtering on same query
You need to a) rewrite your query just a little, and b) I'd recommend using table aliases to make your query more readable.
Try this:
;WITH ProductData AS
(
SELECT
ROW_NUMBER() OVER (PARTITION BY pth.Product_ID
ORDER BY pth.Product_ID, ps.sl_No DESC) AS rno,
tph.product_ID,
tph.process_ID,
ps.sl_No
FROM
Production.tblProcessSequence ps
INNER JOIN
Production.tblProductProcessHdr pph ON tph.product_Process_ID = ps.product_Process_ID
AND pph.isQC_Need = 1
INNER JOIN
Production.tblProductTemplateHdr tph ON tph.product_Temp_ID = pph.product_Temp_ID
)
SELECT *
FROM
ProductData
WHERE
rno = 1
The ROW_NUMBER() function partitions your data by Product_ID and within each partition, it orders the rows by sl_No DESC - so the highest value of sl_No gets the rno = 1 value (all others get higher numbers, in each partition)
You can use another windowed function:
MAX(tblProcessSequence.sl_No) OVER(PARTITION BY tblProductTemplateHdr.product_ID)
ADDENDUM
Just to give the full query in context in case the above was not clear:
SELECT ROW_NUMBER() OVER (PARTITION BY tempHdr.Product_ID ORDER BY Seq.sl_No DESC) AS rno,
tempHdr.product_ID,
procHdr.process_ID,
Seq.sl_No,
MAX(Seq.sl_No) OVER(PARTITION BY tblProductTemplateHdr.Product_ID) AS Max_SL_No
FROM Production.tblProcessSequence Seq
INNER JOIN Production.tblProductProcessHdr procHdr
ON Seq.product_Process_ID = tblProductProcessHdr.product_Process_ID
AND procHdr.isQC_Need = 1
INNER JOIN Production.tblProductTemplateHdr tempHdr
ON tempHdr.product_Temp_ID = procHdr.product_Temp_ID
