DELETE FROM Login WHERE NOT IN (SELECT * FROM Login ORDER BY timeOfLogin DESC LIMIT 3)

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'IN (SELECT * FROM Login ORDER BY timeOfLogin DESC LIMIT 3)' at line 1

det jag vill göra, är att radera alla poster som INTE finns med i
"SELECT * FROM Login ORDER BY timeOfLogin DESC LIMIT 3"
