How to get data everyday's eight AM.? MySQL database, I have a table which contains some column. First column is datatime type, like "2016-03-01 08:00:00", "2016-03-02 08:00:00". 

What should i do to get everyday's 8 AM. from this table?
WHERE TIME(dt) = '08:00:00' is another way to filter on exactly 8am.
