Is using SELECT Max(ID) FROM table safer than using SELECT last_insert_id(), where they run

Is using SELECT Max(ID) FROM table safer than using SELECT last_insert_id(), where they run as 2 separate queries?

I’m concerned that before the last_insert_id() can run, another insert will take place.

    Is using SELECT Max(ID) FROM table safer than using SELECT last_insert_id()

    Definitely not, never! LAST_INSERT_ID() exists exactly for the reason you state: Other clients could have made other inserts. LAST_INSERT_ID() always gives you the last inserted ID on the current connection.
