In a Nutshell

Learn how to join more than two tables in a single query. This hands-on tutorial focuses on practical implementation of joins with multiple tables concepts.

Joining 3+ Tables

You can join as many tables as needed in a single query.

Syntax

SELECT Orders.OrderID, Customers.CustomerName, Shippers.ShipperName
FROM ((Orders
INNER JOIN Customers ON Orders.CustomerID = Customers.CustomerID)
INNER JOIN Shippers ON Orders.ShipperID = Shippers.ShipperID);

Strategy

  1. Start with the main table.
  2. Join the first related table.
  3. Join the next related table using the appropriate keys.

Simulation

Since our default playground only has Customers and Products which aren't directly linked, we can't easily demonstrate a 3-table join effectively without creating more schema.

[!TIP] In real-world applications like e-commerce, you often join Orders, OrderDetails, Products, and Customers to get a full invoice view.

-- Conceptual Example
SELECT 
    c.CustomerName, 
    p.ProductName, 
    o.OrderDate
FROM Orders o
JOIN Customers c ON o.CustomerID = c.CustomerID
JOIN OrderDetails od ON o.OrderID = od.OrderID
JOIN Products p ON od.ProductID = p.ProductID;
