Filter by datetime MYSQL formatting

Question

I have a Mysql Table that is used for a log file on the that table there is a field called \'log_date\' And it stores the date in the following format( %Y-%m-%d %H:%i.%s ).O

Answer 1

log_date should be of DateTime data type. It is much simpler to use MySQL DATE function. Some examples

SELECT * FROM log_table
WHERE DATE(log_date) < '2013-05-05'

SELECT * FROM log_table
WHERE DATE(log_date) > '2013-05-05'

SELECT * FROM log_table
WHERE DATE(log_date) BETWEEN '2013-04-05' AND '2013-05-05'

SELECT * FROM log_table
WHERE DATE(log_date) BETWEEN DATE(CURRENT_DATE() - INTERVAL 2 WEEK) AND 
DATE(CURRENT_DATE() + INTERVAL 4 DAY)
