HomeDatabaseMysql Tutorialmysql中sql语句使日期增加一年_MySQL

mysql表中有一些字段是显示日期的。因为各种需要,需要将它时间往后调整1年。

mysql 日期增加一年的更新语句更新的语句如下:

    UPDATE table SET date = DATE_ADD(date, INTERVAL 1 YEAR)

如果要增加1天,则后面的 1 YEAR 变成 1 DAY,1月则是 1 MONTH

注意如果是多年或者多月或者多天,如3年

后面是写 3 YEAR ,并不需要复数。所以不要写成 3 YEARS Novell迷,迷Novell

mysql 日期增加一年,一月,一日,多年多月多日就不用愁了! 版权所有,未经Novell迷允许,不得转载!

如果要往前呢?则将数字写成负数即可。如减1年,则写 -1 YEAR

注意,还有方法写的是select ,比如

SELECT OrderId,DATE_ADD(OrderDate,INTERVAL 45 DAY) AS OrderPayDate
FROM Orders

这个只是临时在你查询的时候显示而已。并不实际更新数据库中的数据。
