SQL INSERT INTO() VALUES()

Why is this code not working:

-- Insert "Mark Hapka", "Jessica Rothe", "Eric Jungmann" and "Constance Wu" into the actors table.

INSERT INTO actors VALUES (NULL, "Mark Hapka"), (NULL, "Jessica Rothe"), (NULL, "Eric Jungmann"), (NULL, "Constance Wu");

If I add (id, name) after actors it still comes back saying "Query returned no results."

Generally auto-increment ID fields are disregarded.

This is a bit of a guess since you did not refer to the course, but I'm guessing that "ID" is an auto-increment field. So you can disregard it entirely:

INSERT INTO actors (name)
  VALUES ("Mark Hapka"), ("Jessica Rothe"), ("Eric Jungmann"), ("Constance Wu");

If that's not it, please provide a link to the course page you are working with to enable a complete analysis.

Thanks, Steven. But why do we need separate parentheses for each name?

Even though only one column is being filled, the parentheses identify that each entry represents an entire row.
