在MySQL中获得所有月份的最后日子？
要获取所有月份的最后几天，请使用MySQL的LAST_DAY()函数-
SELECT LAST_DAY(yourColumnName) from yourTableName;
让我们首先创建一个表-
mysql> create table DemoTable ( ShippingDate date );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values('2019-01-12');
mysql> insert into DemoTable values('2019-02-01');
mysql> insert into DemoTable values('2019-03-04');
mysql> insert into DemoTable values('2019-04-21');使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
输出结果
+--------------+ | ShippingDate | +--------------+ | 2019-01-12 | | 2019-02-01 | | 2019-03-04 | | 2019-04-21 | +--------------+ 4 rows in set (0.00 sec)
以下是获取MySQL中所有月份的最后几天的查询-
mysql> select LAST_DAY(ShippingDate) from DemoTable;
输出结果
+------------------------+ | LAST_DAY(ShippingDate) | +------------------------+ | 2019-01-31 | | 2019-02-28 | | 2019-03-31 | | 2019-04-30 | +------------------------+ 4 rows in set (0.00 sec)
