如何解决 MySql "Cannot execute this command" 错误？

Question

当我尝试运行这个命令时

select name, address, age into outfile 'user.csv' FIELDS TERMINATED BY ',' 
LINES TERMINATED BY '\n' from StudentTable;"

我从 MySql 收到一个错误：

"ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement"

Answer 1

使用

SELECT @@secure_file_priv;

查看什么文件夹是安全的。

如果returnsf.e

C:\ProgramData\MySQL\MySQL Server 8.0\Uploads\

使用

select name, address, age into outfile 'C:\ProgramData\MySQL\MySQL Server 8.0\Uploads\user.csv' 
    FIELDS TERMINATED BY ',' 
    LINES TERMINATED BY '\n' 
from StudentTable;

反斜杠必须加倍

禁用 my.ini 文件中的更改

[mysqld]
secure-file-priv = ""

但这是不安全的，因为你可以保存在任何你有写权限的地方，也必须指定你想写的文件夹，例如

c:\temp\user.csv
