Insert Statement Challenge

Hi there

When I run this code { INSERT INTO products (id, name, description, price) VALUES (1, "jeans", "hdksjfjee nfis", 9.9); }

for the challenge it gives me an error saying that I only entered 3 values when it expects 4 entries, even though I actually did provide 4 entries.

I have no idea why this is happening.

The table already has 3 entries, your code should insert a 4th. So the error message is just saying it did not work.

The clue is where the instructions say "The id column is auto incrementing." An auto-increment column should not be given an explicit value, so the "id" column can be given a "null" value, or it can be omitted entirely.

I actually first tried omitting the "id" value because it's auto incrementing and it didn't work. But I now tried inserting a NULL value and it worked. Thanks a lot.

This would also work:

INSERT INTO products (name, description, price) VALUES ("jeans", "hdksjfjee nfis", 9.9);

Happy coding!
