MySQL 如何过滤日期以仅获取特定月份的日期记录

首先让我们创建一个表 –

mysql> create table DemoTable
(
   AdmissionDate varchar(100)
);
Query OK, 0 rows affected (1.06 sec)

使用插入命令在表中插入一些记录 –

mysql> insert into DemoTable values('2018-01-21');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('2019-08-13');
Query OK, 1 row affected (0.56 sec)
mysql> insert into DemoTable values('2019-07-08');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('2016-02-12');
Query OK, 1 row affected (0.14 sec)

使用select语句显示表中的所有记录 –

mysql> select *from DemoTable;

这将产生以下输出 –

+---------------+
| AdmissionDate |
+---------------+
| 2018-01-21    |
| 2019-08-13    |
| 2019-07-08    |
| 2016-02-12    |
+---------------+
4 rows in set (0.00 sec)

以下是在MySQL中过滤日期并仅获取8月份日期记录的查询 –

mysql> select *from DemoTable where AdmissionDate like '2019-08%';

这将产生以下输出 –

+---------------+
| AdmissionDate |
+---------------+
| 2019-08-13    |
+---------------+
1 row in set (0.04 sec)
