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

SELECT * FROM
(
SELECT DISTINCT(TRUNC(receipt_dstamp))
FROM inventory
WHERE substr(location_id,1,3) = 'GI-'
ORDER BY 1 ASC
)
WHERE ROWNUM <= 5
Output:
Hi all, i've got this subeqery and in this case my oldest date is in row 1, i want to retrive only second from the last(from the top in this case) which is gonna be 01-SEP-21.
I was trying to play with ROWNUM and OVER but without any results, im getting blank output.
Thank you.
Full query:
SELECT TRUNC(receipt_dstamp) as old_putaway_date, COUNT(tag_id) as tag_old_putaway
FROM inventory
WHERE substr(location_id,1,3) = 'GI-'
AND TRUNC(receipt_dstamp) IN (
SELECT * FROM
(
SELECT DISTINCT(TRUNC(receipt_dstamp))
FROM inventory
WHERE substr(location_id,1,3) = 'GI-'
ORDER BY 1 ASC
)
WHERE ROWNUM = 1
)
GROUP BY TRUNC(receipt_dstamp);
You should be able to simplify the entire query to:
SELECT old_putaway_date,
COUNT(tag_id) as tag_old_putaway
FROM (
SELECT TRUNC(receipt_dstamp) as old_putaway_date,
tag_id,
DENSE_RANK() OVER (ORDER BY TRUNC(receipt_dstamp)) AS rnk
FROM inventory
WHERE substr(location_id,1,3) = 'GI-'
)
WHERE rnk = 3
GROUP BY
old_putaway_date;
You can use dense_rank() :
SELECT * FROM (
SELECT L.*,DENSE_RANK()
OVER (PARTITION BY L.TAG_OLD_PUTAWAY ORDER BY L.OLD_PUTAWAY_DATE DESC) RNK
FROM
(
SELECT TRUNC(receipt_dstamp) as old_putaway_date, COUNT(tag_id) as tag_old_putaway
FROM inventory
WHERE substr(location_id,1,3) = 'GI-'
AND TRUNC(receipt_dstamp) IN (
SELECT * FROM
(
SELECT DISTINCT(TRUNC(receipt_dstamp))
FROM inventory
WHERE substr(location_id,1,3) = 'GI-'
ORDER BY 1 ASC
)
WHERE ROWNUM = 1
)
GROUP BY TRUNC(receipt_dstamp)
) L
) WHERE RNK = 2
You are using an old Oracle syntax that is not standard compliant in the regard that it relies on a subquery result order. (Sub)query results are unordered data sets by definition, but Oracle lets this pass in order to make their ROWNUM work with it.
Oracle now supports the standard SQL FETCH clause, which you should use instead.
SELECT DISTINCT TRUNC(receipt_dstamp) AS receipt_date
FROM inventory
WHERE SUBSTR(location_id, 1, 3) = 'GI-'
ORDER BY receipt_date
OFFSET 2 ROWS
FETCH NEXT 1 ROW ONLY;

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 the following table:
I want to get the most recent status for each dept_code that a CL_ID has. So the desired output would be this:
I have tried the following but this give me just the most recent status for each client and not each of their dept_codes.
SELECT *
FROM [CIMSHR6_MERGED].[dbo].[C3CLSTAT] C
INNER JOIN
(SELECT CLIENT_NUMBER, MAX(STATUS_DATE) AS SDATE
FROM [CIMSHR6_MERGED].[dbo].[C3CLSTAT]
GROUP BY CLIENT_NUMBER) X
ON X.CLIENT_NUMBER = C.CLIENT_NUMBER
AND X.SDATE = C.STATUS_DATE
ORDER BY C.CLIENT_NUMBER
Any help would be much appreciated. Thanks.
A convenient method that works in SQL Server is:
select top (1) cl.*
from [CIMSHR6_MERGED].[dbo].[C3CLSTAT] cl
order by row_number() over (partition by cl_id, dept_code order by status_date desc);
A method that is efficient with the right indexes in almost any database is:
select cl.*
from [CIMSHR6_MERGED].[dbo].[C3CLSTAT] cl
where cl.status_date = (select max(cl2.status_date)
from [CIMSHR6_MERGED].[dbo].[C3CLSTAT] cl2
where cl2.cl_id = cl.cl_id and cl2.dept_code = cl.dept_code
);
The right index is on (cl_id, dept_code, status_date).
I would also use ROW_NUMBER, but with a subquery:
SELECT CL_ID, Status_date, Status, Dept_code
FROM
(
SELECT *,
ROW_NUMBER() OVER (PARTITION BY CL_ID, Dept_code ORDER BY Status_date DESC) rn
FROM CIMSHR6_MERGED].[dbo].[C3CLSTAT]
) t
WHERE rn = 1;
1) Firstly group everything on Dept_Code,CL_ID and assign rank for each row with in the group in descending order.
2) Select all the rows with rnk=1 which would display your desired result.
SELECT Z.CL_ID,
Z.Status_Date,
Z.Status,
Z.Dept_Code
FROM
(
SELECT *,
RANK() OVER( PARTITION BY Dept_Code,CL_ID, ORDER BY Status_Date DESC ) AS rnk
FROM [CIMSHR6_MERGED].[dbo].[C3CLSTAT]
) Z
WHERE Z.rnk = 1;
This would work for almost all databases
select * from c3clstat c
where exists
(select 1 from c3clstat c1
where c1.cl_id=c.cl_id
and c1.dept_code=c.dept_code
group by cl_id,dept_code
having c.status_date=max(c1.status_date)
)
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!
SELECT
ROW_NUMBER()over(partition by tblProductTemplateHdr.product_ID
order by tblProductTemplateHdr.product_ID, tblProcessSequence.sl_No) AS rno,
tblProductTemplateHdr.product_ID
,tblProductProcessHdr.process_ID
,tblProcessSequence.sl_No
FROM
Production.tblProcessSequence
INNER JOIN
Production.tblProductProcessHdr ON tblProductProcessHdr.product_Process_ID = tblProcessSequence.product_Process_ID AND tblProductProcessHdr.isQC_Need = 1
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
