如何通过MySQL查询使用BirthDate列获取Age？

Question

我在MySQL数据库表中有一个BirthDate列来存储用户的出生日期。现在我在html / php中有两个字段（1。年龄从2.年龄到）。

如果用户想要让所有年龄介于10岁到20岁之间的用户，是否可以使用BirthDate列进行MySQL查询。

Answer 1

您的查询与此类似：

SELECT * FROM your_table WHERE YEAR(CURDATE())-YEAR(BirthDate) BETWEEN 10 AND 20;

Answer 2

你可以这样做

SELECT column1, column2, 
   DATE_FORMAT(FROM_DAYS(TO_DAYS(now()) - TO_DAYS(dob)), '%Y') + 0 as age     
WHERE age >10 AND age <20 ; 

Answer 3

select * from table where
(year(curdate())-year(dob))-(right(curdate(),5)< right(dob,5) )
between 10 and 20

Answer 4

另一种检查年份和月份的解决方案：

SELECT * FROM yourTable WHERE FLOOR(DATEDIFF(curdate(), birthdate) / 365.25) BETWEEN 10 AND 20

Answer 5

也可以使用子查询来实现：

select *
    from (select *, TIMESTAMPDIFF(YEAR, birthday, NOW()) as age from table_name) as sub_query
    where age between 10 AND 20
