使用DATE_SUB（）和Now（）函数：

从$ log
中选择count（*）作为cnt
其中date> = DATE_SUB（NOW（），INTERVAL 1 HOUR）;

希望它可以帮助你：）

I keep a record of logins in a table. I have columns for id, ip, date and time. From that record of logins I wanna fetch logins made only in the last hour.

I'm sweaping through the MySQL docs on time and date functions, but I just can't seem to combine them correctly.

Can somebody help me?

Make use of the DATE_SUB() and Now() functions:

select count(*) as cnt
from  log
where date >= DATE_SUB(NOW(),INTERVAL 1 HOUR); 

Hope it helps you : )
