Question

I have a script that sends out emails every minute. When it starts its loop, it queries the database for all entries that are equal to the current utc time. I would like to have it find all entries in the database that correspond to the current time down to the minute.

So there is a ‘time’ column that stores the utc time: ‘2009-03-06 20:18:31’. When it searches is there any way to ignore the seconds attribute with out changing how I store the time?

EDIT: I’m using mysql server.

Thanks!

Answer 1

this was the actual sql statement that I used. Notice that it was heavy influenced by Quassnoi’s response but there are some key differences. I used the UTC_TIMESTAMP instead of NOW().

select *  from table where time < UTC_TIMESTAMP() + INTERVAL(1) MINUTE  - INTERVAL (EXTRACT(SECOND FROM UTC_TIMESTAMP())) SECOND  and time >= UTC_TIMESTAMP() - INTERVAL (EXTRACT(SECOND FROM UTC_TIMESTAMP())) SECOND;
