mysql中怎麼根據生日(brithday)獲取年齡

語法

YEAR(from_days(datediff(now(), sbirthday)));

舉例

首先先創建一個表

create table studentone(
sname varchar(20) not null,
sbirthday datetime
)charset=utf8;

再插入數據

insert into studentone values('陳奇','2000-11-02');
insert into studentone values('陳飛','1999-12-05');
insert into studentone values('周杰','1989-03-01');
insert into studentone values('昆凌','1989-04-15');
insert into studentone values('王麗','1999-05-16');
insert into studentone values('蔡蔡','2000-08-17');

查看錶

要求：將studentone表裏面的sname及其年齡查詢出來
代碼

SELECT sname,YEAR(from_days(datediff(now(), sbirthday)))
FROM studentone;

運行結果
