在 MySQL 查询中将时间戳转换为日期

2021-11-20 00:00:00 sql mysql date-formatting

我想将 MySQL 中的 timestamp 转换为日期.

I want to convert a timestamp in MySQL to a date.

我想将 user.registration 字段格式化为yyyy-mm-dd.

I would like to format the user.registration field into the text file as a yyyy-mm-dd.

这是我的 SQL:

$sql = requestSQL("SELECT user.email, 
                   info.name, 
                   FROM_UNIXTIME(user.registration),
                   info.news
                   FROM user, info 
                   WHERE user.id = info.id ", "export members");

我还尝试了日期转换:

DATE_FORMAT(user.registration, '%d/%m/%Y')
DATE(user.registration)

我在写入文本文件之前回显结果，然后得到:

I echo the result before to write the text file and I get :

email1;name1;DATE_FORMAT(user.registration, '%d/%m/%Y');news1

email1;name1;DATE_FORMAT(user.registration, '%d/%m/%Y');news1

email2;name2;news2

email2;name2;news2

如何将该字段转换为日期?

How can I convert that field to date?

推荐答案

DATE_FORMAT(FROM_UNIXTIME(`user.registration`), '%e %b %Y') AS 'date_formatted'
