您可以从MySQL使用DATE_ADD()函数。让我们首先创建一个表-
mysql> create table DemoTable -> ( -> ShippingDate varchar(100) -> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values('06-01-2019'); mysql> insert into DemoTable values('01-04-2017'); mysql> insert into DemoTable values('29-06-2019');
使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
输出结果
+--------------+ | ShippingDate | +--------------+ | 06-01-2019 | | 01-04-2017 | | 29-06-2019 | +--------------+ 3 rows in set (0.00 sec)
以下是向MySQL函数str_to_date()添加几天的查询。在这里,我们增加了6天-
mysql> select date_add(str_to_date(ShippingDate,'%d-%m-%Y'),interval 6 day) as newShippingDate from DemoTable;
输出结果
+-----------------+ | newShippingDate | +-----------------+ | 2019-01-12 | | 2017-04-07 | | 2019-07-05 | +-----------------+ 3 rows in set (0.00 sec)
