MySQL选择日期等于今天

Question

我正在尝试运行一个mysql select语句,它查看今天的日期,只返回当天注册的结果.我目前尝试了以下内容,但它似乎不起作用.

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') 
    FROM users 
    WHERE users.signup_date = CURDATE()

我已经修改了我的SELECT声明,谢谢你们.

SELECT id FROM users WHERE DATE(signup_date) = CURDATE()

Answer 1

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') 
FROM users 
WHERE DATE(signup_date) = CURDATE()

Answer 2

如果您有signup_date字段,此查询将使用索引

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') 
    FROM users 
    WHERE signup_date >= CURDATE() && signup_date < (CURDATE() + INTERVAL 1 DAY)

Answer 3

听起来你需要将格式添加到WHERE:

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') 
FROM users 
WHERE DATE_FORMAT(users.signup_date, '%Y-%m-%d') = CURDATE()
