How to INSERT INTO SELECT statement in MYSQL?

Question

I need to insert into a database information about a NEW booking for a passenger who has already booked a flight on the same day. I have been lingering on this problem for quite some time now with limited success. Here is where I am at so far:

INSERT INTO BOOKING(name, DOB, flightNumber, departAirport, departTime, class, bookingTime)
SELECT * 
FROM BOOKING 
WHERE departTime = '2019/05/05 06:05';  

I know that this is not correct in regards to what the question is asking me to do. I have set up a fiddle here to help better understand my problem: https://www.db-fiddle.com/f/ngtB4SPcuK4PfMG3sQhwtP/0

Data of same:

Here is the error I recieve due to the fact that the data is not NEW like the question is asking, but the same as another piece of insert data:

Query Error: Error: ER_DUP_ENTRY: Duplicate entry 'Josef-1982-11-27-QF401-SYD-2019-05-05 06:05:00-ECONOMY-2019-04-2' for key 'PRIMARY'

Answer 1

You already have this entry in your db and your primary key contains all fields so you can't add the same thing in that database.
