mysql - INSERT with SELECT

Question

I have a query that inserts using a SELECT statement:

INSERT INTO courses (name, location, gid) 
SELECT name, location, gid 
FROM courses 
WHERE cid = $cid

Is it possible to only select "name, location" for the insert, and set gid to something else in the query?

Answer 1

Yes, absolutely, but check your syntax.

INSERT INTO courses (name, location, gid)
SELECT name, location, 1
FROM   courses
WHERE  cid = 2

You can put a constant of the same type as gid in its place, not just 1, of course. And, I just made up the cid value.
