Great! Let's see how DEFAULT works in practice.
In the author table, the photo column stores either a path to the image if one exists or the string 'imgs/no-photo.jpg' (the default value). The default value will be put into the column if no other value is inserted into this field.
INSERT INTO author (id, first_name, last_name, photo, create_timestamp, is_active) VALUES (1, 'Gregory', 'Smith', DEFAULT, '2018-08-25', 1);
DEFAULT occupies the fourth position in the VALUES list, which corresponds to the photo column. When this record is inserted, the string 'imgs/no-photo.jpg' will go into the photo column. Here's what the result looks like:
| id | first_name | last_name | photo | create_timestamp | is_active |
|---|---|---|---|---|---|
| 1 | Gregory | Smith | imgs/no-photo.jpg | 2018-08-25 00:00:00.0 | 1 |
Let's add the data for Cindy Barry into the author table. She should have an ID of 2, a photo path set to 'imgs/cindy.jpg', and a registration date of '2018-08-27'.
We don't know if Cindy wants to have an active account yet, so we'll leave this as a DEFAULT value.
List columns using the DEFAULT value for the last column.
