1,371 PointsAuto incrementing a column example please!
I was wondering if someone could provide me with an example of EXACTLY how to use NULL to auto increment a column.

when performing the insertion. I'm just going to use the books
table from workspaces.
INSERT INTO books VALUES(NULL, 'A Game of Thrones', 'George R. R. Martin', 'Fantasy', '1996');
Alternatively, you an specify the columns and skip the auto increment column.
INSERT INTO books (title, author, genre, first_published) VALUES('A Clash of Kings', 'George R. R. Martin', 'Fantasy', '1998');
