在MySQL中将当前日期增加11天
让我们首先创建一个表-
mysql> create table DemoTable1994 ( ArrivalDate date );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1994 values('2019-12-18');
mysql> insert into DemoTable1994 values('2019-12-19');
mysql> insert into DemoTable1994 values('2019-12-20');
mysql> insert into DemoTable1994 values('2019-12-25');
mysql> insert into DemoTable1994 values('2018-12-20');使用select语句显示表中的所有记录-
mysql> select * from DemoTable1994;
这将产生以下输出-
+-------------+ | ArrivalDate | +-------------+ | 2019-12-18 | | 2019-12-19 | | 2019-12-20 | | 2019-12-25 | | 2018-12-20 | +-------------+ 5 rows in set (0.00 sec)
这是向当前日期MySQL添加11天的查询-
mysql> select ArrivalDate,date_add(ArrivalDate,interval 11 Day) from DemoTable1994 where ArrivalDate=curdate();
这将产生以下输出-
+-------------+---------------------------------------+ | ArrivalDate | date_add(ArrivalDate,interval 11 Day) | +-------------+---------------------------------------+ | 2019-12-20 | 2019-12-31 | +-------------+---------------------------------------+ 1 row in set (0.00 sec)
