JOIN in SQL Server - Examples & AI Generator

JOINs in SQL Server are essential for combining data across multiple tables, but memorizing the syntax—or adapting it between databases—can slow you down. Whether you’re switching from MySQL, picking up SQL for analytics, or need production-ready code fast, JOIN syntax in SQL Server comes with nuances that trip up even experienced users. AI2sql eliminates this friction: describe your data relationship in plain English, and get optimized JOIN queries in just 10 seconds—no coding required.

JOIN Syntax in SQL Server

SQL Server supports several JOIN types, with a specific syntax. The most common ones are:

• INNER JOIN: Returns rows with matching values in both tables.

• LEFT JOIN (or LEFT OUTER JOIN): Returns all rows from the left table, matched rows from the right.

• RIGHT JOIN (or RIGHT OUTER JOIN): Returns all rows from the right table, matched rows from the left.

• FULL JOIN (or FULL OUTER JOIN): Returns all rows when there is a match in either table.

SQL Server JOIN Syntax:

SELECT columns
FROM TableA
JOIN_TYPE TableB
  ON TableA.column = TableB.column;

Note: CROSS JOIN and self-joins also follow specific SQL Server conventions.

JOIN Examples You Can Generate Instantly

• Find customers and their orders (INNER JOIN):

SELECT Customers.CustomerName, Orders.OrderDate, Orders.Amount
FROM Customers
INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID;

• Show all products, including those never sold (LEFT JOIN):

SELECT Products.ProductName, Orders.OrderID
FROM Products
LEFT JOIN Orders ON Products.ProductID = Orders.ProductID;

• List all customers and the products they've ordered (combining JOINs):

SELECT Customers.CustomerName, Products.ProductName
FROM Customers
INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID
INNER JOIN Products ON Orders.ProductID = Products.ProductID;
