为了安全起见，MySQL8.0默认不允许客户端从本地载入文件。客户端local_infile默认关闭，因此需要在安全路径下导入本地文件。

方法一：在workbench客户端操作

查看安全路径

show variables like '%secure%';

找到安全路径，将数据文件放在此路径下

然后执行如下命令导入数据（emp表结构已创建好）

表名不能是中文，’\‘在编程语言中是转义符，因此要改为’\\'或‘/’

load data infile "C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/employee.csv"

into table emp

fields terminated by ','

ignore 1 lines;

若安全路径为NULL，可以在命令行（cmd）中打开导入外部数据的权限后，在命令行（cmd）中导入数据，具体操作步骤参见方法二。

方法二：在命令行（cmd）中操作

启动cmd

进入MySQL安装路径

使用如下命令登录：

mysql --local-infile=1 -u root -p

登陆成功后，选择进入数据库并查看是否有导入外部数据的权限：

mysql> use test;

mysql> show global variables like 'local_infile';

+---------------+-------+

| Variable_name | Value |

+---------------+-------+

| local_infile | OFF |

+---------------+-------+

1

2

3

4

5

6

打开导入外部数据的权限

mysql> set global local_infile = 'ON';

mysql> show global variables like 'local_infile';

+---------------+-------+

| Variable_name | Value |

+---------------+-------+

| local_infile | ON |

+---------------+-------+

1

2

3

4

5

6

然后再进行数据导入（emp表结构已创建好）注意关键字local

路径中不能有中文，’\‘在编程语言中是转义符，因此要改为’\\'或‘/’

mysql> load data local infile "C:/Users/EDZ/Desktop/employee.csv"

into table emp

fields terminated by ','

ignore 1 lines;

mysql> select * from emp;

| 7934 | miller | clerk | 7782 | 1982-01-23 | 1300 | NULL | 10 |

+-------+--------+-----------+------+------------+------+------+--------+

最后查看数据导入成功即可。
