LIMIT restricts the number of rows returned by a query in database systems that support LIMIT syntax.

Limiting joined results is useful when previewing data or retrieving only a small number of records.

Display the first ten customer orders after joining customer and order information.

SQL 
SELECT
    c.CustomerName,
    o.OrderID,
    o.OrderAmount
FROM Customers c
INNER JOIN Orders o
    ON c.CustomerID = o.CustomerID
ORDER BY o.OrderAmount DESC
LIMIT 10;
