            Comment [ Should also be documented on the *CREATE TABLE* page, under the *DEFAULT Column Option* heading. The text currently says:

            From MariaDB 10.2.1 you can use most functions in DEFAULT. Expressions should have parentheses around them. If you use a non deterministic function in DEFAULT then all inserts to the table will be replicated in row mode. *You can even refer to earlier columns in the DEFAULT expression*:
            ...

            But there's no indication that the "earlier columns" cannot be AUTO_INCREMENT. ]
