Copy and Paste Rows into Same SQL Table with Different Values

Question

I wrote an application for resident housing at a college. In one of the tables (rooms) I have a list of all the rooms and their current/max occupancy. Now, I've added a new column called "semester" and set all of the existing rows to have a semester value of "fall." Now I want copy and paste all of these rows into the table but change the semester value to "spring." The result should be twice as many rows as I started with - half with fall in the semester value and half with spring. Wondering what the best way to accomplish this is?

Answer 1

INSERT INTO rooms
(roomname, current_occupancy, max_occupancy, semester)
SELECT roomname, current_occupancy, max_occupancy,'spring'
FROM rooms
WHERE [semester]='fall'

(assuming names for your room and occupancy columns)
