Scenario: You are tasked with retrieving customer information from a database that includes two tables, "Customers" and "Orders." You need to find customers who have placed orders. Which type of SQL JOIN should you use for this task?
- FULL JOIN
- INNER JOIN
- LEFT JOIN
- RIGHT JOIN
An INNER JOIN retrieves records from both tables where there is a match between the columns specified in the JOIN condition. Since you need to find customers who have placed orders, you want to retrieve records from both the "Customers" and "Orders" tables where there is a match on the customer ID in both tables, making INNER JOIN the appropriate choice.
