对于年月日期获取，您可以在MySQL中使用YEAR()和MONTH()运行。让我们首先创建一个表-mysql> create table DemoTable
(
Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
ShippingDate datetime
);
使用插入命令在表中插入一些记录-mysql> insert into DemoTable(ShippingDate) values('2019-01-31');
mysql> insert into DemoTable(ShippingDate) values('2018-12-01');
mysql> insert into DemoTable(ShippingDate) values('2019-06-02');
mysql> insert into DemoTable(ShippingDate) values('2019-11-18');
使用select语句显示表中的所有记录-mysql> select *from DemoTable;
输出结果+----+-----------------------+
| Id | ShippingDate |
+----+-----------------------+
| 1 | 2019-01-31 00 :00 :00 |
| 2 | 2018-12-01 00 :00 :00 |
| 3 | 2019-06-02 00 :00 :00 |
| 4 | 2019-11-18 00 :00 :00 |
+----+-----------------------+
4 rows in set (0.00 sec)
以下是根据特定年份和月份获取日期的查询-mysql> select *from DemoTable where ( year(ShippingDate)='2019') and (month(ShippingDate)='06');
输出结果+----+-----------------------+
| Id | ShippingDate |
+----+-----------------------+
| 3 | 2019-06-02 00 :00 :00 |
+----+-----------------------+
1 row in set (0.07 sec)
