Question

我有一个用于上传用户图库的表格。我需要使用gallery.created_at的用户上传2个月或更长时间。我试过这个，但它给了我0个结果

    select `galleries`.`client_id` as `client_id`, 
        `users`.`first_name` as `first_name` from `galleries` 
        inner join `users` on `users`.`id` = `galleries`.`client_id` 
        where `galleries`.`session_id` is null and 
       `galleries`.`is_video` = '1' and `galleries`.`is_thumb` = '1' and
        galleries.created_at >= galleries.created_at - INTERVAL 2 MONTH 
   `galleries`.`client_id` not in (select `client_id` from 
        `orders`)

Answer 1

问题出在这里：

galleries.created_at >= galleries.created_at - INTERVAL 2 MONTH

且缺少AND。

或许curdate可能就是您所需要的：

select g.client_id as client_id,
    u.first_name as first_name
from galleries g
inner join users u on u.id = g.client_id
where g.session_id is null
    and g.is_video = '1'
    and g.is_thumb = '1'
    and g.created_at <= curdate() - INTERVAL 2 MONTH
    and g.client_id not in (
        select client_id
        from orders
        )

我使用<=因为您的要求声明上传了2个月或更长时间。

Mysql-选择已上传超过2个月的数据
