Consider the following SQL query:SELECT * FROM orders WHERE order_id I...
The query selects all rows from the "orders" table where the "order_id" column matches any "order_id" values returned by the subquery, which selects order IDs from the "order_items" table where the "quantity" is greater than 10. Therefore, the output will be orders with at least one order item having a quantity greater than 10.

Explanation:

Orders with at least one order item having a quantity greater than 10

- The given SQL query uses a subquery to select order IDs from the order_items table where the quantity is greater than 10.
- The main query then selects all columns from the orders table where the order ID matches any of the order IDs returned by the subquery.
- This means that the query will return all orders that have at least one order item with a quantity greater than 10.
- It does not require all order items to have a quantity greater than 10, only at least one.

Therefore, the correct interpretation of the SQL query is that it retrieves orders with at least one order item having a quantity greater than 10.
