Thanks - helped me get rid of 900k rows of usermeta after removing customers from a Woocommerce site for export 👍
This is very useful. Thank you @carlosleopoldo
It was Great! worked for me.
Bravo!
Found a shorter one:
DELETE FROM wp_usermeta WHERE user_id NOT IN (SELECT ID FROM wp_users);
Deleted my admin user for some reason. Dev site so I'm safe.
