让我们首先创建一个表-

mysql> create table DemoTable1795
     (
     Name varchar(20),
     DueDate date
     );

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable1795 values('John','2018-07-21');
mysql> insert into DemoTable1795 values('Sam','2019-10-21');
mysql> insert into DemoTable1795 values('Sam','2019-01-10');
mysql> insert into DemoTable1795 values('Mike','2018-12-31');

使用select语句显示表中的所有记录-

mysql> select * from DemoTable1795;

这将产生以下输出-

+------+------------+
| Name | DueDate    |
+------+------------+
| John | 2018-07-21 |
| Sam  | 2019-10-21 |
| Sam  | 2019-01-10 |
| Mike | 2018-12-31 |
+------+------------+
4 rows in set (0.00 sec)

这是查询以获取几个月范围内的记录-

mysql> select * from DemoTable1795
     where (YEAR(DueDate) = YEAR(DATE_SUB(CURDATE(), INTERVAL 1 YEAR))
         AND MONTH(DueDate) BETWEEN 7 AND 12)
     OR (YEAR(DueDate) = YEAR(CURRENT_DATE())
         AND MONTH(DueDate) BETWEEN 1 AND 7);

这将产生以下输出-

+------+------------+
| Name | DueDate    |
+------+------------+
| John | 2018-07-21 |
| Sam  | 2019-01-10 |
| Mike | 2018-12-31 |
+------+------------+
3 rows in set (0.00 sec)
