如何在SQL中选择php date（）格式

Question

I have an SQL table with a field "time_created" in the form "Wed, 19 Aug 2015 03:58:00 -0600" . I need to check this field against today and perform a where statement according to it, as in

SELECT * FROM table WHERE UNIX_TIMESTAMP() - UNIX_TIMESTAMP(time_created) >= 3600*24*30

to select records where time_created is older then a month.

Problem is UNIX_TIMESTAMP doesn't understand formats as "Wed, 19 Aug 2015 03:58:00 -0600" . Any other way?

Answer 1

Try:

SELECT *
FROM table 
WHERE DATE(NOW()) > DATE_SUB(STR_TO_DATE(time_created, '%a, %e %b %Y %T'), INTERVAL 1 MONTH)

This will find all records where the current date ( DATE(NOW()) ) is bigger than time_created subtract ` month.
