Ok, the hotel table holds the hotel names and the travel.nome_hotel also
hold the table name (why? becuase the client need it that time). Now I
create the hotel table and dumped all the hotel names from the travel
table to the hotel table. Now that is done I need to remove the the hotel
names from the travel.nome_hotel and give them the corresponding id from
the hotel table. I was thinking something like this
update travel set nome_hotel=hotel.id where
hotel.hotelname=travel.nome_hotel.
It does not work. What would be the corret way?

This will just display the rows. I need to update the travel table with
the id of hotel table based on the hotel names being the same.
