Can anyone who knows SQL, specifically the flavor used in Microsoft Access 2013, tell me what I'm doing wrong here?
SELECT custid, custname, ordno, itemno, itemname
FROM cust
INNER JOIN order
ON cust.custid = order.custid
INNER JOIN orderitems
ON order.ordno = orderitems.ordno
INNER JOIN inv
ON orderitems.itemno = inv.itemno;
I've already read other, similar questions, and tried the methods they used in their solutions, but I'm getting a "Syntax error in FROM clause.", almost no matter what I try.
* * *
SOLUTION: Thanks for the replies! In addition to adding square brackets around "order" and using TableName.ColumnName syntax in SELECT, I had to use parentheses for my multiple INNER JOINs. Here is the fixed code:
SELECT cust.custid, cust.custname, [order].ordno, orderitems.itemno, inv.itemname
FROM ((cust
INNER JOIN [order]
ON cust.custid = [order].custid)
INNER JOIN orderitems
ON [order].ordno = orderitems.ordno)
INNER JOIN inv
ON orderitems.itemno = inv.itemno;
SELECT cust.custid --<-- Use two part name here
,cust.custname
,[order].ordno
,orderitems.itemno --<-- Only guessing here use the correct table name
,inv.itemname --<-- Only guessing here use the correct table name
FROM cust
INNER JOIN [order]
ON cust.custid = [order].custid --<-- used square brackets [] around ORDER as it is
INNER JOIN orderitems -- a key word.
ON [order].ordno = orderitems.ordno
INNER JOIN inv
ON orderitems.itemno = inv.itemno;
In your Select Statament you need to use Two Part name i.e TableName.ColumnName since these column can exist in more than one Tables in your FROM clause you need to tell sql server that columns in your select coming from which table in your from clause.

This is working fine
SELECT i.*,o.*,p.*
FROM orders o
INNER JOIN oitems i
ON i.orderid = o.orderid
LEFT OUTER JOIN products p
ON i.catalogid = p.catalogid
however i want to perform a nested select as an example this is giving the coulmn x exists more than once
SELECT AA.*,
FROM (
SELECT i.*,o.*,p.*
FROM orders o
INNER JOIN oitems i
ON i.orderid = o.orderid
LEFT OUTER JOIN products p
ON i.catalogid = p.catalogid ) AA
i know the second example makes no sense , but i need another select with groupping, is there a way to fix the coulm exists more than once error without having to specify the column names in the select statement?
By using *, you are getting the same column more than once in your output. To avoid, this, specifically state the columns you want returned, instead.
The culprits are likely orderid and catalogid which both exist in more than one table, but there may be others.
You have mention column names specifically. I can see that you are using "*". you have to use like select i.columnName,o.columnName etc
Im practicing basic SQL with this site http://www.sqlishard.com/Exercise
Here is the question:
S5.0 - INNER JOIN
Now that we can pull data out of a single table and qualify column
names, let's take it a step further. JOIN statements allow us to
'join' the rows of several tables together using a condition to define
how they match one another. SELECT [columns] FROM FirstTable INNER
JOIN SecondTable ON FirstTable.Id = SecondTable.FirstTableId
Try using the INNER JOIN syntax to SELECT all columns from the
Customers and Orders tables where the CustomerId column in Orders
matches the Id column in Customers. Since both tables have an Id
column, you will need to qualify the Customers id in the WHERE clause
with either the table name or a table alias.
Here is my answer:
SELECT *
FROM Customers AS c
INNER JOIN Orders AS o ON c.ID = o.ID
WHERE o.CustomerID = c.ID
The site says im wrong? Could anyone explain where i'm going wrong?
EDIT: I see now I dont need the WHERE clause, but the question states..
you will need to qualify the Customers id in the WHERE clause with
either the table name or a table alias.
Hence my confusion. Thanks none the less.
Try this way:
SELECT c.ID,o.ID
FROM Customers AS c
INNER JOIN Orders AS o ON o.CustomerID = c.ID
or using where clause
SELECT *
FROM Customers AS c, Orders AS o
where o.CustomerID = c.ID
If you use JOIN.. ON, you do not need where clause
I have this query:
select carrier_id, order_id,aircraft_id,quantity
from orderline
innerjoin purchaseorder on orderline.order_id = purchaseorder.carrier_id;
im getting the ambiguous error, I know I have to use aliases but it doesnt work ie:
select carrier_id as cID, order_id as OID,aircraft_id,quantity
from orderline
innerjoin purchaseorder on orderline.order_id as OID = purchaseorder.carrier_id as cID
it says invalid relational operator ?
thanks for your help guys :)
You need a space in your INNER JOIN. Not INNERJOIN.
select carrier_id, order_id,aircraft_id,quantity
from orderline
inner join purchaseorder on orderline.order_id = purchaseorder.carrier_id;
Also, as the other answerer said, your columns may be ambiguously defined (same column name in each table), so you need to prefix the columns with your table name i.e.( select orderline.orderid)
The problem is that after you did the JOIN, you are selecting some columns. Some of those columns probably have the same name on both tables, and you need to specify wich one is it:
select P.carrier_id, O.order_id, O.aircraft_id, P.quantity --use the right prefix
from orderline AS O
inner join purchaseorder AS P
on O.order_id = P.carrier_id;
SELECT * FROM Products_Joined, Products
WHERE p.ProductManufacturer = 'Sony'
ORDER BY p.ProductCode
I keep getting the error The multi part identifier p.ProductManufacturer could not be bound
I tried:
Setting the Order By
Adding the PRODUCTS table to the FROM
Is there something I'm missing?
You should use:
SELECT p.*, pj.*
FROM dbo.Products p
INNER JOIN dbo.ProductsJoined pj ON ..... <== add your missing JOIN condition here
WHERE p.ProductManufacturer = 'Sony'
ORDER BY p.ProductCode
First of all: never use SELECT * in your production code.
Secondly: use the proper ANSI JOIN syntax (INNER JOIN..) to clearly show what you're joining, and on what JOIN condition (which is missing in your case - you're producing a cartesian product here.....)
Third: if you use table aliases like p. - you need to define them, too!
You have no p object. You need to alias one of your tables.
SELECT * FROM Products_Joined, Products AS p
WHERE p.ProductManufacturer = 'Sony'
ORDER BY p.ProductCode
That will fix your immediate problem, however you should have a JOIN on your tables or else you are doing a CROSS JOIN, which is usually not preferable. An example of what it would look like is below.
SELECT *
FROM Products_Joined
JOIN Products AS p
ON Products_Joined.ProductsID = p.ProductsID
--This join is a guess on what the common column is between these two tables
--Change as necessary
WHERE p.ProductManufacturer = 'Sony'
ORDER BY p.ProductCode
UPDATE BASED ON YOUR COMMENT
If you received the error even with a Products.ProductManufacturer, then you are probably missing the ProductManufacturer column in the Products table. I would check your schema and verify the column exists.
It's nice to find such a useful site with genius members. I have been trying to find a solution for this SQLITE problem for a while now. Google didn't help me, except in finding this website. The SQL query works fine on the MSAccess version of the same database.
Here's my SQL statement - which didn't work for me.
SELECT Invoices.InvoiceNumber, Invoices.Quantity,Invoices.Code, Invoices.Price,Invoices.Discount, Invoices.InvoiceGrandTotal, Employees.EmployeeName, Customers.CustomerName, Invoices.DateOfInvoice, [price]*[Quantity] AS Total, Customers.Address, Products.Description,Products.Unit
FROM Products
INNER JOIN (
(
( Invoices INNER JOIN InvoiceDetails
ON Invoices.InvoiceNumber = InvoiceDetails.InvoiceNumber
) INNER JOIN Customers
ON Invoices.CustomerID = Customers.CustomerID
) INNER JOIN Employees
ON Invoices.UserID = Employees.EmployeeID
) ON Products.Code = InvoiceDetails.Code
WHERE (((InvoiceDetails.InvoiceNumber)='10111'));
The error message is: "Cannot compile Select-Statement: no such column: Invoices.InvoiceNumber"
That usually just means that you mis-spelled the column name ... check your Invoices table and make sure the column is InvoiceNumber and not "Invoice_Number" or something similar ...
Also, a much simpler version of this query would look something like this .. without all the strange nesting:
SELECT
Invoices.InvoiceNumber,
Invoices.Quantity,
Invoices.Code,
Invoices.Price,
Invoices.Discount,
Invoices.InvoiceGrandTotal,
Employees.EmployeeName,
Customers.CustomerName,
Invoices.DateOfInvoice,
[price]*[Quantity] AS Total,
Customers.Address,
Products.Description,
Products.Unit
FROM
Invoices
JOIN Employees
ON Employees.EmployeeID = Invoices.UserID
JOIN Customers
ON Customers.CustomerID = Invoices.CustomerID
JOIN InvoiceDetails
ON InvoiceDetails.InvoiceNumber = Invoices.InvoiceNumber
JOIN Products
ON Products.Code = InvoiceDetails.Code
WHERE
InvoiceDetails.InvoiceNumber = '10111'
I think the issue might be with case sensitivity. Unless I'm mistaken, MS Access field names are not case sensitive. Check the offending column name for the correct casing in you SQLITE table definition.
