I am getting my face kicked in....
I have a total of 4 tables
1. Business (BusinessID, CustomerID, BusName, Territory)
2. Customer (CustomerID, Name)
3. Sales (BusinessID, CustomerID, Territory, Jan, Feb, Mar, Apr, May, Jun)
4. Performance (this is the table I want the info in)
I've already created the table to have the following columns, BusinessID, CustomerID, BusName, Name, Territory, Jan,Feb,Mar,Apr,May,Jun
Every time I try to insert its not properly joining and I am getting a bunch of errors "multi-part identifier could not be bound"
insert into Performance (BusinessID, CustomerID, BusName, Name, Territory, January2018, February2018, March2018, April2018, May2018, June2018)
select Business.BusinessID, Customer.CustomerID, Business.BusName, Customer.Name, Sales.Territory, Sales.January2018, Sales.February2018, Sales.March2018, Sales.April2018, Sales.May2018, Sales.June2018
from Business A
inner join Customer B ON a.CustomerID = b.CustomerID
inner join Sales C ON b.CustomerID = c.CustomerID;
Due to this error I had to do 3 seperate insert into and that caused a bunch of nulls....
face palm is happening and could use some advice.

You have used table ALIASES, so you have to use those aliases in you SELECT
A for Business, B for Customer and C for Sales.
Read about ALIASES here.
select A.BusinessID, B.CustomerID, A.BusName, B.Name, C.Territory, C.January2018, C.February2018, C.March2018, C.April2018, C.May2018, C.June2018
from Business A
inner join Customer B ON a.CustomerID = b.CustomerID
inner join Sales C ON b.CustomerID = c.CustomerID;
When you create a table alias in your FROM and JOIN clauses, you need to refer to the aliases in your SELECT statement and not the actual table names.
Alternatively, leave your SELECT statement as it is, and adjust your table names to remove the alias. You'll then need the join conditions to refer to your actual table names, rather than the alias. So for example;
select Business.BusinessID, Customer.CustomerID, Business.BusName, Customer.Name, Sales.Territory, Sales.January2018, Sales.February2018, Sales.March2018, Sales.April2018, Sales.May2018, Sales.June2018
from Business
inner join Customer ON Business.CustomerID = Customer.CustomerID
inner join Sales ON Customer.CustomerID = Sales.CustomerID;
Even just try running the SELECT statement above first to make sure you get the query correct before trying it in your insert.

I have five tables that contain artificial data about bank details.
My intention is to select only transactions that took place in a different city than that of the customer they belong to.
In order to do this, I wrote this query:
SELECT c.Cityid,c.FirstName,c.LastName,ci.Name
FROM dbo.Customer c
INNER JOIN dbo.City ci ON ci.ID=c.Cityid
INNER JOIN dbo.Account acc ON acc.CustomerId=c.Id
INNER JOIN dbo.AccountDetails accde ON accde.AccountId=acc.Id
INNER JOIN dbo.Location lo ON lo.LocationTypeId=accde.LocationId
WHERE c.Cityid <>lo.CityId
But unfortunately I have results that are not good and my code listed data which is identical like city of customer, not city of transaction. Probably I have some mistake with WHERE expression.
So can anybody help me how to fix this problem ?
Also here in attachment there is diagram of tables in database.
Additionally here I put screen-shot from Customer table.In last column here there is CityId marked with yellow color.
Each of this customer have some transaction in City which is diffrent than their cities.For example for customer with Id 1 I need to have all other cities that this customer have transaction.In order to achive this I connect customer table with account details and account table.And the end I need to have city for each cusmtomer which is diffrent than their city. Also here I will put Location table
If you want to display city of transaction too, join the city table again:
SELECT
c.FirstName,
c.LastName,
ci.Name as customer_city,
tci.Name as transaction_city
FROM dbo.Customer c
JOIN dbo.City ci ON ci.ID=c.Cityid
JOIN dbo.Account acc ON acc.CustomerId=c.Id
JOIN dbo.AccountDetails accde ON accde.AccountId=acc.Id
JOIN dbo.Location lo ON lo.LocationTypeId=accde.LocationId
JOIN dbo.City tci ON tci.ID=lo.Cityid -- Added join to city from location
WHERE c.Cityid <>lo.CityId
I added another join to City from Location.
I also removed the CityId column, because generally surrogate id’s are meaningless.
I'm new to databases and I'm having a hard time figuring this out. Any assistance would be greatly appreciated
Deliveries Table
-- ID (PK)
-- DriverID (FK to Drivers Table)
Drivers Table
-- ID (PK)
-- LocationID (FK to Locations Table)
Locations Table
-- ID (PK)
-- RestaurantID (FK to Restaurants Table)
Restaurant Table
--ID (PK)
A Restaurant can have multiple locations (1 to many). A location can have multiple drivers (1 to many). a Driver can have multiple deliveries (1 to many). This design is supposed to break things out in 3rd normal form. So if I want to go to the deliveries table and get all of the deliveries associated with a particular restaurant, how would I query or do a join for that? Would I have to add a second foreign key to Deliveries that directly references the Restaurant table? I think after I see the query I can figure out what is going on. Thx
You can use left or right outer join to make a combined table and then you can easily query it, or else you can use a query with multiple sub-queries inside it to attain the required result without using join. Here is an example on how to use sub-query for your use-case.
SELECT ID FROM Deliveries De
WHERE De."DriverID" IN (SELECT ID FROM Drivers Dr
WHERE Dr. "LocationID" IN (SELECT ID FROM Locations L
WHERE L. "RestaurantID" IN (SELECT ID FROM Restaurant)))
I hope this solves your issue without using join statement.
You can use inner join or union depending on what you want to achieve. Example:
SELECT a."articleId" AS id, a.title, a."articleImage" AS "articleImage/url", c.category AS "category/public_id", a."createdOn", concat("firstName", ' ', "lastName") AS author
FROM articles a
INNER JOIN users u ON a."userId" = u."userId"
INNER JOIN categories c ON a."categoryId" = c."categoryId"
UNION
SELECT g."gifId" AS id, g.title, g."imageUrl" AS "articleImage/url", g.public_id AS "category/public_id", g."createdOn", concat("firstName", ' ', "lastName") AS author
FROM gifs g
INNER JOIN users u ON g."userId" = u."userId"
ORDER BY "createdOn" DESC
You can say how you want to get the results for more detailed query.
If I understand what you want to do then it maybe like this,
1st you have to join all those table to get corresponding result you want,
the join condition will be
select <your desire column name>
from Restaurant A,Locations B,Drivers C,Deliveries D
where A.ID = B.RestaurantID
and B.ID = C.LocationID
and C.ID = D.DriverID
Hope this is helpful, fell free to say anything.
I'm using the version of SQL Server which comes with Visual Studio 2017 and trying to create a view by joining columns from four tables which are as follows:
Table1: Employee (EmpID, EmpName, EmpContact, EmpSalary)
Table2: Customer (CustID, CustName, CustContact, CustEmail)
Table3: Orders (OrderID, OrderCustID, OrderDate, OrderStatus, OrderValue)
Orders.OrderCustID is foreign key which relates to Customer.CustID
Table4: Job (JobID, JobOrderID, JobEmpID, JobStatus, JobRemarks)
Job.JobOrderID and Job.JobEmpID are two foreign keys which relate to Orders.OrderID and Employee.EmpID respectively.
Now, I want to perform a join which will show all records of Orders table along with matches from other tables in following order:
OrderID, JobStatus, OrderStatus, CustID, CustName, CustContact, CustDue, EmpID, EmpName, EmpContact, Oredrvalue
Someone please help me write the SQL Query to perform the join. Many thanks in advance.
You need to walk through each JOIN to figure out what to join where. In other words, how do you get from Employees to Customers? It's just a logical walk-through.
Here's one approach, using inner joins (basically a big intersection of sets).
SELECT OrderID, JobStatus, OrderStatus, CustID, CustName, CustContact, CustDue, EmpID, EmpName, EmpContact, OrderValue
FROM Job
INNER JOIN Orders
ON Orders.OrderId=Job.JobOrderID
INNER JOIN Customer
ON Customer.CustId=Orders.OrderCustId
INNER JOIN Employee
ON Employee.EmpId=Job.JobEmpID
OK, I figured it out and I'm posting it here for any future reference.
SELECT o.OrderID, j.JobStatus, o.OrderStatus, c.CustID, c.CustName, c.CustContact, c.CustDue, e.EmpID, e.EmpName, e.EmpContact, o.Oredrvalue
FROM Orders o
LEFT JOIN Customer c
ON o.OrderCustID=c.CustID
LEFT JOIN Job j
ON o.OrderID=j.JobOrderID
LEFT JOIN Employee e
ON j.JobEmpID=e.EmpID
I performed left join on all occasions because I need all the records from Orders table. Thanks a lot to all who responded.
I'm extremely new to SQL Sever and so I apologize if the question is worded strange. I am doing a homework assignment, and this is the question:
"A manager wants to know the email address, number or orders, and the total amount of purchases made by each customer. Create a summary query that returns these three items for each customer that has orders."
I have all of the data queried, the problem is when I pull data from each customer, it will show the quantity of items per order, and I need the items to be pooled together into one column. This is my query thus far (again, total noob, please excuse any poor syntax, etc.)
SELECT EmailAddress,
ItemPrice - DiscountAmount * Quantity AS TotalPurchaseAmount,
COUNT(*) AS OrderQty
FROM Customers
JOIN Orders ON Customers.CustomerID = Orders.CustomerID
JOIN OrderItems ON Orders.OrderID = OrderItems.OrderID
GROUP BY Orders.CustomerID,
OrderItems.ItemPrice, OrderItems.DiscountAmount,
OrderItems.Quantity,
Customers.EmailAddress;
The following is a small bit of the result set that I get:
Email Address OrderTotal OrderQty
allan.sherwood#yahoo.com 253.15 2
allan.sherwood#yahoo.com 839.30 2
allan.sherwood#yahoo.com 1208.16 2
barryz#gmail.com 303.79 4
christineb#solarone.com 479.60 2
david.goldstein#hotmail.com 299.00 2
david.goldstein#hotmail.com 489.30 1
david.goldstein#hotmail.com 479.60 1
So as you can see, I have several orders I need to smoosh together into one single row per e-mail, I have looked and looked for an answer but the only thing I can find is how to find duplicates and ignore them, not combine their data. Any help is extremely appreciate, thanks so much for taking the time to read this :) If my question doesn't make sense please let me know so I can clear up any bad wording I may have used!
Just do GROUP BY CustomerID, EmailAddress:
SELECT
c.EmailAddress,
SUM((i.ItemPrice - i.DiscountAmount) * Quantity) AS TotalPurchaseAmount,
COUNT(*) AS OrderQty
FROM Customers c
INNER JOIN Orders o
ON c.CustomerID = o.CustomerID
INNER JOIN OrderItems i
ON o.OrderID = i.OrderID
GROUP BY
c.CustomerID, c.EmailAddress
Additional note: Use aliases for your tables
You need to change your formula and remove columns that you dont want to group by from select query..
for example your query should be something like this
SELECT EmailAddress,
--do your aggregation here
blah AS TotalPurchaseAmount,
COUNT(*) AS OrderQty
FROM Customers
JOIN Orders ON Customers.CustomerID = Orders.CustomerID
JOIN OrderItems ON Orders.OrderID = OrderItems.OrderID
GROUP BY Orders.CustomerID,
Customers.EmailAddress;
I've never worked with a non-normalized database before, so I'll try and explain my problem as best I can. So I have two tables:
The customers table holds all the customers information, and the orders table holds all the orders that they have placed. I haven't listed all the fields in the tables, just the ones that I need. The customer number in both tables is not the primary key, but I'm inner joining on them anyway. So the problem I'm having is that I don't know how to make a query that:
Selects all the customers with their first name, last name, and email, and also show the most recent orderdate, most recent total, and most recent ordertype. I know that I have to use a max() aggregate for the date, but that's as far as I got. Please help a noob out.
You can try:
SELECT FirstName,
LastName,
Email,
OrderDate,
OrderTotal,
OrderType
FROM Customers AS C
INNER JOIN Order AS O
ON O.CustomerNumber = C.CustomerNumber AND
O.OrderDate = (
SELECT MAX (O1.OrderDate)
FROM Order AS O1
WHERE O1.CustomerNumber = C.CustomerNumber)
)
assuming that Orders.OrderDate is unique for each CustomerNumber, does this work for you? if a single CustomerNumber has more than one entry in Order for OrderDate, you'll get each of those rows.
select c.FirstName, c.LastName, c.Email, o.OrderDate, o.OrderTotal, o.OrderType
from Customers c
join
(select CusomterNumber, max(OrderDate) as MostRecentOrderDate
from Orders
group by CustomerNumber
) mro on mro.CustomerNumber=s.CustomerNumber
join Orders o on o.OrderDate=mro.MostRecentOrdeDate and
o.CustomerNumber=mro.CustomerNumber
Try this:
SELECT
Customers.*, Orders.*
FROM
Customers
JOIN
(SELECT
Customer_Number,
MAX(Order_Date) OrderDate
FROM
Orders
GROUP BY
Customer_Number
) as Ord ON Customers.Customer_Number = Ord.Customer_Number
JOIN Order ON Orders.Customer_Number = Ord.Customer_Number
If you are doing this with SQL Server use the query designer and basically all you want to do is do a join since you have two keys that are the same one in Customer Table ->Customer Join on Order->Customer alias the Customer table as C and Orders table as O
so for example
SELECT Customer.*, Orders.*
From Customer c, Orders O INNER JOIN O where C.Customer Number = O.Customer Number
This should be enough to get you started.. if you don't want all the fields then fully qualify the names for example
SELECT C.FirstName, C.LastName, O.OrderDate, O.OrderType FROM Customer C, Orders O
WHERE C.Customer NUmber = O.Customer Number //this is another way of doing a Join when working with the where Clause.
