MySQL SELECT查询返回具有特定月份和年份的记录

2024-05-01 09:40:04 422

对于特定月份，请使用MONTH()，对于年份，请使用YEAR()方法。让我们首先创建一个表-

mysql> create table DemoTable
(
   StudentName varchar(40),
   StudentAdmissionDate date
);

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable values('Chris','2019-01-21');
mysql> insert into DemoTable values('Robert','2018-09-05');
mysql> insert into DemoTable values('Mike','2019-09-05');
mysql> insert into DemoTable values('David','2019-10-04');

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-

+-------------+----------------------+
| StudentName | StudentAdmissionDate |
+-------------+----------------------+
| Chris       | 2019-01-21           |
| Robert      | 2018-09-05           |
| Mike        | 2019-09-05           |
| David       | 2019-10-04           |
+-------------+----------------------+
4 rows in set (0.00 sec)

以下是查询以返回特定月份和年份的记录-

mysql> select *from DemoTable where month(StudentAdmissionDate)=09 and year(StudentAdmissionDate)=2019;

这将产生以下输出-

+-------------+----------------------+
| StudentName | StudentAdmissionDate |
+-------------+----------------------+
| Mike        | 2019-09-05           |
+-------------+----------------------+
1 row in set (0.00 sec)
