Exercise

Unifying flight formats II

In the previous exercise, you used CONCAT(), REPLICATE(), and LEN(). You got every register with more than 100 delays from the flight_statistics table. In a unique column, you concatenated the carrier_code, registration_code, and airport_code, having a similar format to this one: "AA - 0000119, JFK".

In this exercise, you will solve the same problem again, this time using the FORMAT() and CONCAT() functions together.
