MySQL查询以获取几个月范围内的记录？
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)
