Question

The InstantRide Driver Relationship team wants to check if there are any drivers with zero rides. You need to extract the DRIVER_ID, DRIVER_FIRST_NAME, DRIVER_LAST_NAME of the drivers with zero rides. You can use a subquery with DRIVER_ID compared to ALL rows in TRAVELS.

**Table: Travel Data Records** This table displays a dataset of travel records, each row representing an individual trip. It includes the following columns: 1. **TRAVEL_ID**: A unique identifier for each travel record. 2. **TRAVEL_START_TIME**: The date and time when the travel began. 3. **TRAVEL_END_TIME**: The date and time when the travel concluded. 4. **TRAVEL_START_LOCATION**: The address where the travel started. 5. **TRAVEL_END_LOCATION**: The destination address where the travel ended. 6. **TRAVEL_PRICE**: The cost of the travel in monetary terms. 7. **DRIVER_ID**: A unique identifier for the driver associated with the travel. 8. **CAR_ID**: A unique identifier for the car used in the travel. 9. **USER_ID**: A unique identifier for the user or passenger. 10. **TRAVEL_DISCOUNT**: The discount applied to the travel price, if any, indicated as either a numeric value or NULL if no discount was applied. The dataset showcases various travel instances with details on timing, pricing, and identifiers for drivers, cars, and users. Discounts are applied selectively to some entries. This table format is commonly used in databases to track transportation services and can serve as a basis for further analysis in fields such as logistics, urban planning, or transportation economics.
