I'm using SQL Server 2014 and I have a problem with a query.
I want to have in my report, ALL the items of the order with ID_Order = 9 that have been delivered. And for the items that have been delivered at two times (Item Code = Art3 for example), I just want to have the last row, that means the last delivery of this Item, with NO repetition.
I already tried these two queries without success:
Attempt #1: DISTINCT
SELECT DISTINCT
Order.ItemCode, Delivery. Qty, Delivery.ID_Delivery,
Order.ID_Order
FROM
Delivery
INNER JOIN
Order ON Order.ID_Order = Delivery.ID_Order
WHERE
Order.ID_Order = '9'
Attempt #2: subquery
SELECT *
FROM
(SELECT
Order.ItemCode, Delivery.Qty,
FROM
Delivery
INNER JOIN
Order ON Order.ID_Order = Delivery.ID_Order
WHERE
Order.ID_Order = '9')
GROUP BY
a.ItemCode, a.Qty
Try this query --
;WITH CTE
AS (
SELECT C.ID_Order
,D.ID_Delivery
,C.ItemCode
,C.Quantity
,ROW_NUMBER() OVER (
PARTITION BY C.ItemCode ORDER BY D.ID_Delivery DESC
) AS RowNum
FROM Customer_Order C
INNER JOIN Delivery D ON C.ID_Order = D.ID_Order
AND C.ItemCode = D.ItemCode
WHERE C.ID_Order = 9
)
SELECT ID_Order
,ID_Delivery
,ItemCode
,Quantity
FROM CTE
WHERE RowNum = 1
SELECT
Order.ItemCode, Delivery. Qty, Delivery.ID_Delivery,
Order.ID_Order
FROM
Delivery
INNER JOIN
Order ON Order.ID_Order = Delivery.ID_Order
WHERE
Order.ID_Order = '9'
AND Delivery.ID_Delivery IN
(
SELECT MAX(ID_Delivery) FROM Delivery D WHERE D.ID_Order = Delivery.ID_Order GROUP BY D.ID_Order
)
I hope it will work for you.

I would like to retrieve one large table of products with the latest rows from all the joined tables via with MAX(ID) of each group (productToken) which ich unique name of the product. Joined tables are - products (store), availability (status), description (products), and price of the product. All of them contains the unique productToken and the mentioned tables can be changed over time by adding a new record (independently) so my aim is to compose one big table (with actual info about the products) via retrieving the lastest record from each table. My code is this. First added product worked well, but things got strange after adding new records to any of the tables (query has retrieved no results).
SELECT *
FROM products
JOIN productsStore ON products.productToken = productStore.productToken
JOIN productsStatus ON products.productToken = productsStatus.productToken
JOIN productsPrice ON products.produstToken = productsPrice.productToken
JOIN categories ON products.categoryToken = categories.categoryToken
WHERE products.shopToken = '$shopToken'
AND products.productID IN
(SELECT MAX(productID)
FROM products
GROUP BY productToken)
AND productsPrice.productPriceID IN
(SELECT MAX(productPriceID)
FROM productsPrice
GROUP BY produktToken)
AND productsStatus.productStatusID IN
(SELECT MAX(productStatusID)
FROM productsStatus
GROUP BY productToken)
AND produktyStore.productStoreID IN
(SELECT MAX(productStoreID)
FROM productsStore
GROUP BY productToken)
AND categories.categoryID IN
(SELECT MAX(categoryID)
FROM categories
GROUP BY categoryToken)
ORDER BY categories.categoryID DESC
I would like to retrieve one large table of products with the latest rows from all the joined tables
I think that you want equality conditions with correlated subqueries in the where clause rather than in conditions with aggregate queries. This lets you filter each joined table with the "latest" record for the given productToken.
SELECT *
FROM products p
JOIN productsStore psr ON psr.productToken = p.productToken
JOIN productsStatus psu ON psu.productToken = p.productToken
JOIN productsPrice ppr ON ppr.produstToken = p.productToken
JOIN categories c ON c.categoryToken = p.categoryToken
WHERE
p.shopToken = '$shopToken'
AND p.productID = (SELECT MAX(p1.productID) FROM products p1 WHERE p1.productToken = p.productToken)
AND psr.productStoreID = (SELECT MAX(psr1.productStoreID) FROM productsStore psr1 WHERE psr1.productToken = p.productToken)
AND psu.productStatusID = (SELECT MAX(psu1.productStatusID) FROM productStatus psu1 WHERE psu1.productToken = p.productToken)
AND ppr.productPriceID = (SELECT MAX(ppr1.productPriceID) FROM productsPrice ppr1 WHERE ppr1.productToken = p.productToken)
AND c.categoryID = (SELECT MAX(c1.categoryID) FROM category c1 WHERE c1.productToken = p.productToken)
If you are running MySQL 8.0 (or MariaDB 10.3 or higher), you can use ROW_NUMBER() in subqueries instead:
SELECT *
FROM (
SELECT p.*, ROW_NUMBER() OVER(PARTITION BY productToken ORDER BY productID DESC) rn
FROM products p
) p
INNER JOIN (
SELECT psr.*, ROW_NUMBER() OVER(PARTITION BY productToken ORDER BY productStoreID DESC) rn
FROM productsStore psr
) psr ON psr.productToken = p.productToken AND psr.rn = 1
INNER JOIN (
SELECT psu.*, ROW_NUMBER() OVER(PARTITION BY productToken ORDER BY productStatusID DESC) rn
FROM productsStatus psu
) psu ON psu.productToken = p.productToken AND psu.rn = 1
INNER JOIN (
SELECT ppr.*, ROW_NUMBER() OVER(PARTITION BY productToken ORDER BY productsPriceID DESC) rn
FROM productsPrice ppr
) ppr ON ppr.productToken = p.productToken AND ppr.rn = 1
INNER JOIN (
SELECT c.*, ROW_NUMBER() OVER(PARTITION BY productToken ORDER BY categoryID DESC) rn
FROM categories c
) c ON c.productToken = p.productToken AND c.rn = 1
WHERE p.shopToken = '$shopToken' AND p.rn = 1
I have the following SQL Server code to get information from a combination of 4 tables.
I would like to modify it to only retrieve the latest 3 orders (pmpOrderDate) by supplier (pmpSupplierOrganizationID).
SELECT
PO.pmpPurchaseOrderID, PO.pmpOrderDate, PO.pmpSupplierOrganizationID, O.cmoName
FROM
PurchaseOrders PO
INNER JOIN
PurchaseOrderLines POL ON PO.pmpPurchaseOrderID = POL.pmlPurchaseOrderID
INNER JOIN
Organizations O ON PO.pmpSupplierOrganizationID = O.cmoOrganizationID
INNER JOIN
Parts P ON POL.pmlPartID = P.impPartID
WHERE
P.impPartClassID LIKE 'PUMP%'
Can you please help?
EDIT:
I wasn't fully clear on my actual requirements. To clarify further, what I need in the end is to display the latest 3 unique Purchase Orders by Supplier ID based on at least one of the PartClassID for the PartID in the PurchaseOrderLines to have criteria of beginning with string 'PUMP'
Use a ROW_NUMBER to partition by pmpSupplierOrganizationID and order by pmpOrderDate.
with cteTopOrders AS (
SELECT PO.pmpPurchaseOrderID, PO.pmpOrderDate, PO.pmpSupplierOrganizationID, O.cmoName,
ROW_NUMBER() OVER(PARTITION BY pmpSupplierOrganizationID ORDER BY pmpOrderDate DESC) AS RowNum
FROM PurchaseOrders PO
Inner Join PurchaseOrderLines POL ON PO.pmpPurchaseOrderID = POL.pmlPurchaseOrderID
Inner Join Organizations O On PO.pmpSupplierOrganizationID = O.cmoOrganizationID
Inner Join Parts P ON POL.pmlPartID = P.impPartID
WHERE P.impPartClassID Like 'PUMP%'
)
SELECT pmpPurchaseOrderID, pmpOrderDate, pmpSupplierOrganizationID, cmoName
FROM cteTopOrders
WHERE RowNum <= 3;
I'm a fan of lateral joins for this . . . cross apply:
select p.*, O.cmoName
from Organizations O cross apply
(select top (3) PO.pmpPurchaseOrderID, PO.pmpOrderDate, PO.pmpSupplierOrganizationID
from PurchaseOrders PO join
PurchaseOrderLines POL
on PO.pmpPurchaseOrderID = POL.pmlPurchaseOrderID join
Parts P
on POL.pmlPartID = P.impPartID
where PO.pmpSupplierOrganizationID = O.cmoOrganizationID and
P.impPartClassID Like 'PUMP%'
order by PO.pmpOrderDate desc
) p
You need a nested row_number to get the three rows per supplier and another OLAP-function on top of it:
with OrderRowNum as
(
SELECT PO.pmpPurchaseOrderID, PO.pmpOrderDate, PO.pmpSupplierOrganizationID, O.cmoName, P.impPartClassID,
row_number()
over (partition by PO.pmpSupplierOrganizationID
order by pmpOrderDate desc) as rn
FROM PurchaseOrders PO
Inner Join PurchaseOrderLines POL ON PO.pmpPurchaseOrderID = POL.pmlPurchaseOrderID
Inner Join Organizations O On PO.pmpSupplierOrganizationID = O.cmoOrganizationID
Inner Join Parts P ON POL.pmlPartID = P.impPartID
)
, CheckPUMP as
(
select *,
-- check if at least one of the three rows contains PUMP
max(case when impPartClassID Like 'PUMP%' then 1 else 0 end)
over (partition by PO.pmpSupplierOrganizationID) as PUMPflag
from OrderRowNum
where rn <= 3 -- get the last three rows per supplier
)
select *
from CheckPUMP
where flag = 1
I'm struggling with a left outer join where the right portion, the one that could contain nulls, doesn't show me values. I think the situation is called an implicit inner join. The reason is that the subquery doesn't return nulls but rather nothing for what I'd like to have on my right part.
(This question differs from Left Outer Join Not Working? in that a subquery to find the maximum date is needed.)
Here is a simplified example:
Table Contracts:
customer_id, status
Table Values:
customer_id, value_code, value, begin_date
I want to display all customers with status = 'active' and the latest value for a certain value_code, lets say 'volume'. There are more value_codes and the values have a certain date from which they are valid. There can also be no value_code BUT then I want a NULL on the right side.
So here is what I tried to do:
SELECT * FROM CONTRACTS C
LEFT JOIN VALUES V ON C.CUSTOMER_ID = V.CUSTOMER_ID
AND VALUE_CODE = 'VOLUME'
WHERE C.STATUS = 'ACTIVE'
AND V.BEGIN_DATE = (
SELECT MAX(BEGIN_DATE) FROM VALUES V2
WHERE V2.CUSTOMER_ID = V.CUSTOMER_ID
AND V2.VALUE_CODE = 'VOLUME'
)
I can't put the subquery in the join clause, Oracle won't accept that. On the other hand my subquery makes it so that all the rows that have no entry for a value with code 'volume' are omitted. What I want is to have value = NULL instead with all the customers on the left.
Thanks for helping!
Filter the VALUE rows first and then LEFT JOIN:
SELECT *
FROM CONTRACTS C
LEFT JOIN
( SELECT *
FROM (
SELECT V.*,
ROW_NUMBER() OVER ( PARTITION BY CUSTOMER_ID ORDER BY BEGIN_DATE DESC )
AS rn
FROM VALUES V
)
WHERE rn = 1
) V
ON ( C.CUSTOMER_ID = V.CUSTOMER_ID
AND VALUE_CODE = 'VOLUME' )
WHERE C.STATUS = 'ACTIVE'
As MT0 suggested using partitioning and sorting by row number helped. Only had to include value_code in the partitioning for my purpose.
So this query finally did what I wanted:
SELECT *
FROM CONTRACTS C
LEFT JOIN
( SELECT *
FROM (
SELECT V.*,
ROW_NUMBER() OVER ( PARTITION BY CUSTOMER_ID, VALUE_CODE ORDER BY BEGIN_DATE DESC )
AS rn
FROM VALUES V
)
WHERE rn = 1
) V
ON ( C.CUSTOMER_ID = V.CUSTOMER_ID
AND VALUE_CODE = 'VOLUME' )
WHERE C.STATUS = 'ACTIVE'
I have two different sources of information and I am trying to marry them together to get information relating to a customer and their last bill. I have managed to get details of each customer and their max billing period end date but I am unsure as to how I can then get the details from the associated bill. I have the following query:
SELECT new_mprnnumber,
new_customernumber,
MAX(b.billingPeriodEndDate) as 'Billed up to date'
FROM [CRM].[crm4_MSCRM].[dbo].[AccountExtensionBase] as a
inner join Billing.dbo.bill as b
on a.new_mprnnumber = b.MPRN
where new_accountstage = 7
and new_accounttype = 2
group by new_mprnnumber,
new_customernumber
GO
The bill has fields like amount due etc but I only want to return details of those from the max dated bill, any help would be greatly appreciated
Use a CTE with row_number()
with CTE as
(
select a.new_mprnnumber,
a.new_customernumber,
b.*,
row_number()
over (partition by new_customernumber -- add additional partitions as you would group bys
order by billingPeriodEndDate desc) as r_ord
from AccountExtensionBase a
inner join bill b
on a.new_mprnnumber = b.MPRN
where new_accountstage = 7
and new_accounttype = 2
)
select *
from CTE
where r_ord = 1
Put your query into a CTE and then link back to table bill:
WITH CTE AS (
SELECT new_mprnnumber,
new_customernumber,
MAX(b.billingPeriodEndDate) as MaxBillDate
FROM [CRM].[crm4_MSCRM].[dbo].[AccountExtensionBase] as a
inner join Billing.dbo.bill as b
on a.new_mprnnumber = b.MPRN
where new_accountstage = 7
and new_accounttype = 2
group by new_mprnnumber,
new_customernumber
)
SELECT b.*
FROM CTE c
INNER JOIN Billing.dbo.bill b ON c.MaxBillDate = b.billingPeriodEndDate AND c.new_mprnnumber = b.MPRN
Using SQL Server 2012
I have seen a few threads about this topic but I can't find one that involves multiple joins in the query. I can't create a VIEW on this database so the joins are needed.
The Query
SELECT
p.Price
,s.Type
,s.Symbol
, MAX(d.Date) Maxed
FROM AdventDW.dbo.FactPrices p
INNER JOIN dbo.DimSecurityMaster s
ON s.SecurityID = p.SecurityID
INNER JOIN dbo.DimDateTime d
ON
p.DateTimeKey = d.DateTimeKey
GROUP BY p.Price ,
s.Type ,
s.Symbol
ORDER BY s.Symbol
The query works but does not produce distinct results. I am using Order by to validate the results, but it is not required once I get it working. I The result set looks like this.
Price Type Symbol Maxed
10.57 bfus *bbkd 3/31/1989
10.77 bfus *bbkd 2/28/1990
100.74049 cbus 001397AA6 8/2/2005
100.8161 cbus 001397AA6 7/21/2005
The result set I want is
Price Type Symbol Maxed
10.77 bfus *bbkd 2/28/1990
100.74049 cbus 001397AA6 8/2/2005
Here were a few other StackOverflow threads I tried but couldn't get t work with my specific query
How can I SELECT rows with MAX(Column value), DISTINCT by another column in SQL?
SQL Selecting distinct rows from multiple columns based on max value in one column
If you want data for the maximum date, use row_number() rather than group by:
SELECT ts.*
FROM (SELECT p.Price, s.Type, s.Symbol, d.Date,
ROW_NUMBER() OVER (PARTITION BY s.Type, s.Symbol
ORDER BY d.Date DESC
) as seqnum
FROM AdventDW.dbo.FactPrices p INNER JOIN
dbo.DimSecurityMaster s
ON s.SecurityID = p.SecurityID INNER JOIN
dbo.DimDateTime d
ON p.DateTimeKey = d.DateTimeKey
) ts
WHERE seqnum = 1
ORDER BY s.Symbol;
You should use a derived table since you really only want to group the DateTimeKey table to get the MAX date.
SELECT p.Price ,
s.Type ,
s.Symbol ,
tmp.MaxDate
FROM AdventDW.dbo.FactPrices p
INNER JOIN dbo.DimSecurityMaster s ON s.SecurityID = p.SecurityID
INNER JOIN
( SELECT MAX(d.Date) AS MaxDate ,
d.DateTimeKey
FROM dbo.DimDateTime d
GROUP BY d.DateTimeKey ) tmp ON p.DateTimeKey = tmp.DateTimeKey
ORDER BY s.Symbol;
/*
this is your initial select which is fine because this is base from your original criteria,
I cannot ignore this so i'll keep this in-tact. Instead from here i'll create a temp
*/
SELECT
p.Price
, s.Type
, s.Symbol
, MAX(d.Date) Maxed
INTO #tmpT
FROM AdventDW.dbo.FactPrices p
INNER JOIN dbo.DimSecurityMaster s
ON s.SecurityID = p.SecurityID
INNER JOIN dbo.DimDateTime d
ON p.DateTimeKey = d.DateTimeKey
GROUP BY p.Price ,
s.Type ,
s.Symbol
ORDER BY s.Symbol
SELECT innerTable.Price, innerTable.Symbol, innerTable.Type, innerTable.Maxed
FROM (
SELECT
ROW_NUMBER () OVER (PARTITION BY t1.Symbol, t1.Type, t1.Maxed ORDER BY t1.Maxed DESC) as row
, *
FROM #tmpT AS t1
) AS innerTable
WHERE row = 1
DROP TABLE #tmpT
