Please, I need your help, I'm new to the subject, so I have tow tables Order table and Order Detail table. I want to sum order amount in the order table and group by the product id exists in the order detail table. I'm getting repeated rows.
select p.productName
SUM(o.Amount - o.discount) as OrdersTotal
FROM dbo.order o
inner join
OrderDetail d
ON o.orderid = d.orderid
inner join
dbo.product p
ON d.productid = p.productid
where o.orderdate >= #fromdate
and o.orderdate <= #todate
group by p.productname, o.discount
the result I'm getting is as follow
product name orders total
------------ ------------
product A 150
product A 20
product B 45
product B 13
so please, how can I fix this result? Thanks
You should only group on the product name, so that all records with the same product name are included in the sum of the amount:
select p.productName
SUM(o.Amount) as OrdersTotal
FROM dbo.order o
inner join
OrderDetail d
ON o.orderid = d.orderid
inner join
dbo.product p
ON d.productid = p.productid
where o.orderdate >= #fromdate
and o.orderdate <= #todate
group by p.productname

I have been trying to solve this but couldn't find a way to get the total purchase value while grouping with the customer table
I would recommend using a Common Table Expression (CTE) as, in my experience, it helps with scalability/maintenance down the road and easily enables you to see what the data is under the hood if you wanted to simply run the CTE itself.
I join the Customer to the Order to get the OrderID
I join the Order to OrderDetails to get the ProductID and Order Quantity
I join the OrderDetails to Products to get the Price
I join the Categories to filter for just Beverages
All this is wrapped as a CTE (similar to a subquery), on top of which I can now aggregate at the Customer level and sequence by Order Value in a descending fashion.
with beverage_orders_cte as(
SELECT c.CustomerName, o.OrderID
, od.OrderDetailID, od.ProductID, od.Quantity
, p.ProductName, p.Price
, od.Quantity * p.Price as OrderVal
,cat.CategoryName FROM Customers c
inner join Orders o
on c.CustomerID = o.CustomerID
inner join OrderDetails od
on o.OrderID = od.OrderID
inner join Products p
on od.ProductID = p.ProductID
inner join Categories cat
on p.CategoryID = cat.CategoryID and cat.CategoryID = 1
)
select CustomerName, SUM(OrderVal) as Revenue
From beverage_orders_cte
Group by CustomerName
Order by Revenue desc
Limit 5
Hope this helps, good luck.
Something like that?
SELECT c.customerid,
Sum(p.price)
FROM customers AS c
INNER JOIN orders AS o
ON o.customerid = c.customerid
INNER JOIN orderdetails AS od
ON od.orderid = o.orderid
INNER JOIN products AS p
ON p.productid = od.productid
GROUP BY c.customerid
ORDER BY Sum(p.price) DESC
LIMIT 5
Just following on from your quantity comment...
SELECT c.customerid,
Sum(p.price),
Sum(p.price * od.quantity)
FROM customers AS c
INNER JOIN orders AS o
ON o.customerid = c.customerid
INNER JOIN orderdetails AS od
ON od.orderid = o.orderid
INNER JOIN products AS p
ON p.productid = od.productid
GROUP BY c.customerid
ORDER BY Sum(p.price) DESC
LIMIT 5
I think this is the best optimized code.
Please try with this.
SELECT CustomerID, Count(Quantity * Price) AS Total
FROM Orders, OrderDetails, Products
Where Orders.OrderID = OrderDetails.OrderID AND Products.ProductID = OrderDetails.ProductID
Group by CustomerID
ORDER BY Total DESC
LIMIT 5
I need to get (sales.customers) | year | gross_sales of top ten customers that made at least 5 purchases of Category "Beverages" in the year 2014. I have already written these SELECT queries, but since I am new to SQL, I think I am very inefficient in writing code. This does not work properly and there is probably a simpler way of doing it. I have also pinned a picture of an ER diagram .
SELECT
T6.COMPANYNAME, YEAR, GROSS_SALES
FROM
(SELECT T1.CUSTID
FROM
(SELECT R.CUSTID, COUNT(R.CUSTID) AS NUMBEROFSALES
FROM SALES.ORDERDETAILS O
RIGHT JOIN PRODUCTION.PRODUCTS P ON P.PRODUCTID = O.PRODUCTID
RIGHT JOIN SALES.ORDERS R ON R.ORDERID = O.ORDERID
INNER JOIN SALES.CUSTOMERS C1 ON R.CUSTID = C1.CUSTID
INNER JOIN PRODUCTION.CATEGORIES C2 ON P.CATEGORYID = C2.CATEGORYID
WHERE C2.CATEGORYNAME = 'Beverages' AND YEAR(R.ORDERDATE) = 2014
GROUP BY R.CUSTID
ORDER BY SUM(R.CUSTID) DESC) T1
--HAVING COUNT(R.CUSTID) > 5
RIGHT JOIN
(SELECT R.CUSTID, SUM(O.UNITPRICE) AS MONEYSPENT
FROM SALES.ORDERDETAILS O
RIGHT JOIN PRODUCTION.PRODUCTS P ON P.PRODUCTID = O.PRODUCTID
RIGHT JOIN SALES.ORDERS R ON R.ORDERID = O.ORDERID
INNER JOIN SALES.CUSTOMERS C1 ON R.CUSTID = C1.CUSTID
INNER JOIN PRODUCTION.CATEGORIES C2 ON P.CATEGORYID = C2.CATEGORYID
WHERE C2.CATEGORYNAME = 'Beverages' AND YEAR(R.ORDERDATE) = 2014
GROUP BY R.CUSTID
ORDER BY SUM(O.UNITPRICE) DESC) T2 ON T1.CUSTID = T2.CUSTID
ORDER BY T1.NUMBEROFSALES DESC
LIMIT 10) T5
INNER JOIN
(SELECT DISTINCT(T4.COMPANYNAME), T4.CUSTID, YEAR, GROSS_SALES
FROM
(SELECT R.CUSTID AS CUSTID, YEAR(R.ORDERDATE) AS YEAR, SUM(O.UNITPRICE * O.QTY * (1 - O.DISCOUNT)) AS GROSS_SALES
FROM SALES.ORDERDETAILS O
RIGHT JOIN SALES.ORDERS R ON R.ORDERID = O.ORDERID
INNER JOIN SALES.CUSTOMERS C1 ON R.CUSTID = C1.CUSTID
GROUP BY R.CUSTID, YEAR(R.ORDERDATE)
ORDER BY YEAR(R.ORDERDATE)) T3
INNER JOIN
(SELECT C.COMPANYNAME, C.CUSTID
FROM SALES.ORDERS R
INNER JOIN SALES.CUSTOMERS C ON R.CUSTID = C.CUSTID) T4 ON T3.CUSTID = T4.CUSTID) T6 ON T5.CUSTID = T6.CUSTID
I'm not going to try and fix your code or explain the misakes there, as there are many of them. Instead based on your requirements I wrote a query that solves the problem. I show it in steps below which should make clear the process I used to solve the problem.
First how do we find the top ten customers that made 5 purchases of Beverages?
Take customer table and join to orders with beverages (inner join will exclude customers that don't meet criteria)
SELECT CUSTOMERID
FROM CUSTOMERS C
JOIN ORDERS O ON C.CUSTOMERID = O.CUSTOMERID
JOIN ORDER_DETAILS OD ON O.ORDERID = OD.ORDERID
JOIN PRODUCTS P ON OD.PRODUCTID = P.PRODUCTID
JOIN CATEGORIES C ON P.CATEGORYID = C.CATEGORYID AND C. CATEGORY_NAME = 'Beverages'
WHERE YEAR(ORDER_DATE) = 2014
GROUP BY CUSTOMERID
HAVING COUNT(ORDER_DETAILS) >= 5
Now we need the sum of order (for 2014) by customers which looks like this:
SELECT CUSTOMERID, YEAR(ORDER_DATE) AS YEAR, SUM(OD.UNIT_PRICE*OD.QUANTITY) AS TOTAL_SPEND
FROM CUSTOMERS C
JOIN ORDERS O ON C.CUSTOMERID = O.CUSTOMERID
JOIN ORDER_DETAILS OD ON O.ORDERID = OD.ORDERID
WHERE YEAR(ORDER_DATE) = 2014
GROUP BY CUSTOMERID, YEAR(ORDER_DATE)
Now we just combine these two queries like this:
SELECT CUSTOMERID, YEAR(ORDER_DATE) AS YEAR, SUM(OD.UNIT_PRICE*OD.QUANTITY) AS TOTAL_SPEND
FROM CUSTOMERS C
JOIN ORDERS O ON C.CUSTOMERID = O.CUSTOMERID
JOIN ORDER_DETAILS OD ON O.ORDERID = OD.ORDERID
JOIN (
SELECT CUSTOMERID
FROM CUSTOMERS C
JOIN ORDERS O ON C.CUSTOMERID = O.CUSTOMERID
JOIN ORDER_DETAILS OD ON O.ORDERID = OD.ORDERID
JOIN PRODUCTS P ON OD.PRODUCTID = P.PRODUCTID
JOIN CATEGORIES C ON P.CATEGORYID = C.CATEGORYID AND C. CATEGORY_NAME = 'Beverages'
WHERE YEAR(ORDER_DATE) = 2014
GROUP BY CUSTOMERID
HAVING COUNT(ORDER_DETAILS) >= 5
) as SUB ON SUB.CUSTOMERID = C.CUSTOMERID
WHERE YEAR(ORDER_DATE) = 2014
GROUP BY CUSTOMERID, YEAR(ORDER_DATE)
ORDER BY SUM(OD.UNIT_PRICE*OD.QUANTITY)
LIMIT 10
Note I did not test this but just wrote the SQL since I don't have a db to test against so there might be typos
Also Note: I'm expect it is possible to remove the sub query as it is doing a lot of the same joins the outer query is-- but we want to make sure we get the correct result and it is easier to see it is correct this way. You can also test the sub-query by itself to make sure it returns expected results.
The software we use has two tables for orders, Orders and OrderItems.
I am trying do run a query on the database to show which items have not sold in a period of time.
This is what I have but It's not working ( it brings up all the records)
SELECT
OrderItem.Name,
OrderItem.SKU,
[Order].OrderDate
FROM
[Order]
INNER JOIN OrderItem ON [Order].OrderID = OrderItem.OrderID
WHERE
(OrderItem.SKU NOT IN
(SELECT DISTINCT OrderItem.SKU WHERE ([Order].OrderDate BETWEEN '2014-09-08' AND '2014-01-01')))
You can actually do this with a having clause:
SELECT oi.Name, oi.SKU, max(o.OrderDate) as lastOrderDate
FROM [Order] o INNER JOIN
OrderItem oi
ON o.OrderID = oi.OrderID
GROUP BY oi.Name, oi.SKU
HAVING sum(case when o.OrderDate between '2014-01-01' and '2014-09-08' then 1 else 0 end) = 0;
If you are just looking for orders before this year, it is easier to write the having clause as:
HAVING max(o.OrderDate) < '2014-01-01'
Flip your dates. It should be [Begin Date] Between [End Date]
WHERE (OrderItem.SKU NOT IN
(SELECT DISTINCT OrderItem.SKU
WHERE ([Order].OrderDate BETWEEN '2014-01-01' AND '2014-09-08')))
How about the following:
SELECT oi.Name, oi.SKU, o.OrderDate
FROM [Order] o
INNER JOIN OrderItem oi ON o.OrderID = oi.OrderID
WHERE oi.SKU NOT IN
(
SELECT os.SKU
FROM [Order] os
INNER JOIN OrderItem ois ON os.OrderID = ois.OrderID
WHERE os.OrderDate BETWEEN '2014-01-01' AND '2014-09-08'
)
You have to join to the OrderItem table in the sub query in order to get the SKU.
Looks like your query was build 'upside down'.
SELECT DISTINCT SKU FROM OrderItem oi
WHERE NOT EXISTS
(SELECT 1 FROM Order o
JOIN OrderItem oi2 ON o.OrderID = oi2.OrderID
WHERE oi2.SKU = oi.SKU
AND o.OrderDate BETWEEN '2014-01-01' AND '2014-09-08' );
Ideally, you should have another table containing your distinct items, so you could write the following query to see which items were not sold during a certain period (and may have never been sold at all).
select i.SKU from items
where not exists (
select 1 from OrderItem oi
join Order o on o.OrderID = oi.OrderID
where oi.SKU = i.SKU
and o.OrderDate BETWEEN '2014-01-01' and '2014-09-08'
)
if you don't have such a table, you can select all products that have been ordered at some point, but not during another period
select i.SKU from (
select distinct oi.SKU from OrderItem oi
) i
where not exists (
select 1 from OrderItem oi
join Order o on o.OrderID = oi.OrderID
where oi.SKU = i.SKU
and o.OrderDate BETWEEN '2014-01-01' and '2014-09-08'
)
Select
P.ProductName, WFS.Status, OI.Quantity, OI.Price
from
OrderItem As OI
Inner Join
Order As O On OI.OrderID = O.ID AND OI.ItemType = 1
Inner Join
Product P On OI.ProductID = P.ID
Inner Join
WorfFlowStatus As WFS On O.StatusID = WFS.ID
This query returns the rows:
ProductName Status Quantity Price
-------------------------------------------
ABC Shipped 10 100
ABC Shipped 10 100
BCE Pending 20 200
Now I want to select the same product in one row but quantity and price should be added. For e.g
ABC Shipped 20 200
BCE Pending 20 200
If status and productname is same than add the quantity and price and if product is not the same then no addition in quantity and price.
Select
P.ProductName,
WFS.Status,
sum(OI.Quantity),
sum(OI.Price)
from OrderItem As OI
Inner Join Order As O
On OI.OrderID = O.ID AND OI.ItemType = 1
Inner Join Product P
On OI.ProductID = P.ID
Inner Join WorfFlowStatus As WFS
On O.StatusID = WFS.ID
group by
P.ProductName,
WFS.Status
As pointed out by cha, the Group By clause is the key:
Select P.ProductName,WFS.Status,sum(OI.Quantity),sum(OI.Price)
from OrderItem As OI
Inner Join [Order] As O On OI.OrderID = O.ID AND OI.ItemType = 1
Inner Join Product P On OI.ProductID = P.ID
Inner Join WorkFlowStatus As WFS On O.StatusID = WFS.ID
group by productName, Status
'over with Partition by' can help.
For example
select ProductName,
Status,
Quantity,
(SUM(Quantity) OVER (PARTITION BY ProductName)) as TotalQuantity
FROM YourTableName and joins
select P.ProductName, WFS.Status, sum(OI.Quantity), sum(OI.Price)
from OrderItem OI, Order O, Product P, WorkFlowStatus WFS
where OI.OrderID = O.ID and OI.ItemType = 1 and
OI.ProductID = P.ID and
O.StatusID = WFS.ID
group by productName, Status
How I can write a query that can find me orders having same order lines (details)?
Sample Data
Table: Order
ORDER_ID
--------
A
B
C
D
Table: OrderDetails
OrderID ProductID
------------------
A ProductX
A ProductY
A ProductZ
B ProductX
B ProductY
C ProductZ
D ProductX
D ProductY
D ProductZ
Now I want to pass ProductX,ProductY,ProductZ and get back A and D.
Can this be done in one query?
Maybe something like this is what you want?
SELECT DISTINCT Orders.OrderID
FROM Orders
INNER JOIN OrderDetails ON Orders.OrderID = OrderDetails.OrderID
WHERE OrderDetails.ProductID IN ('ProductX', 'ProductY', 'ProductZ')
GROUP BY Orders.OrderID
HAVING COUNT(*) = 3
Also note that Order is a reserved keyword and should not be used as a table name.
SELECT OrderId FROM
(SELECT DISTINCT o.OrderId, p.Product
FROM Orders o
INNER JOIN OrderDetails p
ON o.OrderId = p .OrderId
WHERE p.Product IN ('ProductX', 'ProductY', 'ProductZ') ) tab
GROUP BY OrderId
HAVING COUNT(*) = 3
I have done the required thing without using the Order table..
SELECT id from ProductT
group by id
having count(*)=3;
SQL Fiddle
Try this
SELECT P.OrderID
FROM Order1 P JOIN OrderDetails D ON
P.OrderID = D.OrderID
WHERE P.OrderID IN (SELECT OrderID FROM OrderDetails WHERE ProductID IN ('ProductX', 'ProductY', 'ProductZ'))
Having Count(P.OrderID)=3
GROUP BY P.OrderID
