Question

I need to get data from multiple tables and put it into a subform.

The SubForm columns are ‘product name’ and ‘quantity’ and they need to list out the products relating to the order ID.

The tables in question are:

PRODUCTS(productID,productName)

ORDER(orderID,prodID,quantity)

Where the prodID in ORDER refers to the PRODUCTS table.

As you can see, the problem is that the name of the product is in a different table to the order. So, the data I need to get is:

Products(productName)

Order(quantity)

In relation to the orderID.

How can I use a SQL query to get this data? I am aware of joins and so on, but I just can’t see how to apply it.

Thank you. I hope this makes sense.

Answer 1

This is a simple inner join between the two tables to return the rows you want:

SELECT P.PRODUCTNAME, O.QUANTITY
FROM PRODUCTS P INNER JOIN ORDER O ON P.PRODUCTID = O.PRODID
WHERE O.ORDERID = <order id>
