要忽略带日期范围的年份，请在DATE_FORMAT()和Between子句之间使用。让我们首先创建一个演示表。创建表的查询如下-

mysql> create table igonreYearDemo
   -> (
   -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> ShippingDate date
   -> );

使用insert命令在表中插入一些记录。查询如下-

mysql> insert into igonreYearDemo(ShippingDate) values('2016-01-31');
mysql> insert into igonreYearDemo(ShippingDate) values('2018-01-31');
mysql> insert into igonreYearDemo(ShippingDate) values('2015-06-23');
mysql> insert into igonreYearDemo(ShippingDate) values('2015-06-23');
mysql> insert into igonreYearDemo(ShippingDate) values('2014-02-01');
mysql> insert into igonreYearDemo(ShippingDate) values('2019-01-31');
mysql> insert into igonreYearDemo(ShippingDate) values('2019-02-14');
mysql> insert into igonreYearDemo(ShippingDate) values('2019-03-12');

使用select语句显示表中的所有记录。查询如下-

mysql> select *from igonreYearDemo;

这是输出-

+----+--------------+
| Id | ShippingDate |
+----+--------------+
| 1  | 2016-01-31   |
| 2  | 2018-01-31   |
| 3  | 2015-06-23   |
| 4  | 2015-06-23   |
| 5  | 2014-02-01   |
| 6  | 2019-01-31   |
| 7  | 2019-02-14   |
| 8  | 2019-03-12   |
+----+--------------+
8 rows in set (0.00 sec)

以下是忽略日期范围内的年份的查询-

mysql> select *from igonreYearDemo tbl where DATE_FORMAT(tbl.ShippingDate, '%m-%d') between '01-01' and '03-31';

这是输出-

+----+--------------+
| Id | ShippingDate |
+----+--------------+
| 1  | 2016-01-31   |
| 2  | 2018-01-31   |
| 5  | 2014-02-01   |
| 6  | 2019-01-31   |
| 7  | 2019-02-14   |
| 8  | 2019-03-12   |
+----+--------------+
6 rows in set (0.00 sec)
