Question

In MYSQL i have DATE and TIME seperated. I need to count how many times one ip failed to login in the last 2 hours. If he failed too many times, then he can’t login for the next 2 hours.

I just don’t know which statement is the correct one (maybe none of the 2 below).

SELECT COUNT(`ip`) AS count_failed_logins FROM `failed_logins` WHERE `time`=TIME(CURTIME()+Interval 2 hour)

or

SELECT COUNT(`ip`) AS count_failed_logins FROM `failed_logins` WHERE `time`=TIMEDIFF(CURTIME()+Interval 2 hour)

Answer 1

You can simply do :

SELECT COUNT(`ip`) FROM `failed_logins` WHERE `time` > DATE_SUB(NOW(), INTERVAL 2 HOUR);
