MySQL日期大于一个月的地方? [英] MySQL Where date is greater than one month?

问题描述

我有一个名为"last_login"的日期时间列.

I have a datetime column called 'last_login'.

我想查询数据库以选择上个月内未登录的所有记录.我该怎么做?

I want to query my database to select all records that haven't logged in within the last month. How do I do this?

这是我目前拥有的:

$query = $this->query("SELECT u.id, u.name, u.email, u.registered, g.name as group_name FROM `:@users` AS u LEFT JOIN `:@groups` AS g on u.group_id = g.id WHERE u.last_login = ...... LIMIT {$limit_start}, {$limit_end}");

:@ =数据库前缀

推荐答案

尝试使用date_sub

where u.last_login < date_sub(now(), interval 1 month)

(类似于第一个答案，但在我看来，使用正整数更为自然")

(Similar to the first answer but in my mind it is more "natural" to use positive integers)
