Question

I’ve been trying to create a shopping basket class and have hit a brick wall when trying to output by shopping basket contents.

My users basket information is stored in a table with the following structure.

     CREATE TABLE IF NOT EXISTS basket (
            `ID` int PRIMARY KEY AUTO_INCREMENT,
            `ProductID` int,
            `Quantity` int,
            `OptionID` int,
            `Cookie` varchar(40)
            ;

Where the Cookie field is a unique identifier for the user stored in a cookie.

My products tables is structured as follows:

    CREATE TABLE IF NOT EXISTS products (
            ID int PRIMARY KEY AUTO_INCREMENT,
            Title varchar(200),
            Description text,
            Specification text,
            Price decimal(10,2),
            CategoryID int,
            Weight int,
            Options text,
            OptionValues text,
            OptionCost text,
            Discount int(2),
            Featured boolean,
            Images text,
            Stock int,
            Related text,
            Offer boolean,
            OfferDetails boolean,
            Language int
            ;

What I want to do SELECT the items from my basket with their respective product Title and price information from the products table.

So in essence I need a sql statement that will output the following using the productID to link the two tables:

ProductID From basket table

Quantity From basket table

Title From products table

Description From products table

Price From products table

I have done a similar thing before by looping through the basket array and then querying the products table with the current ProductID but surely this can be done with one query?

Answer 1

Try this:

SELECT
  b.ProductID,
  b.Quantity,
  p.Title,
  p.Description,
  p.price
From basket b
INNER JOIN products p ON b.ProductID = p.Id;
