An example of an AI chatbot conversation about SQL join operations.
What are SQL join operations?
SQL join operations are used to combine rows from two or more tables based on a related column between them.
Can you explain the different types of joins?
Sure! The main types of joins are INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL OUTER JOIN.
What is the difference between INNER JOIN and LEFT JOIN?
INNER JOIN returns only the rows with matching values in both tables, while LEFT JOIN returns all rows from the left table and matched rows from the right table.
Can you give me an example of a LEFT JOIN?
Certainly! If you have a 'Customers' table and an 'Orders' table, a LEFT JOIN will show all customers and their orders, including customers with no orders.
