按月和日mqsql搜索

Question

我有包含列日期的表消息（格式为DATETIME） 我如何搜索date = xxxx-05-09的邮件？

select * from messages where date = 'xxxx-05-09';

Answer 1

试试这个：

 select * from messages where Extract(Month from date) = 5 and Extract(Day from date) = 9;

Answer 2

您还可以使用DATE_FORMAT函数：

select * from messages where DATE_FORMAT(date, "%Y-%m-%d") = 'xxxx-05-09';
