Question

我有一个存储过程，其中有一个准备好的select ... into outfile语句。当我尝试以root身份调用该过程时，它运行良好，但当我尝试将其作为另一个用户调用时，我一直拒绝访问。

Show grants:
GRANT FILE ON *.* TO 'mls'@'localhost' IDENTIFIED BY ...
GRANT ALL PRIVILEGES ON `mls`.* TO 'mls'@'localhost' WITH GRANT OPTION

我错过了什么吗？提前感谢任何想法。

这适用于MySQL 5.5：

以root身份登录

USE mls;
GRANT FILE ON *.* TO 'mls'@'localhost' IDENTIFIED BY ...;
GRANT SELECT, EXECUTE ON `mls`.* TO 'mls'@'localhost';
CREATE TABLE t1 ( a INT );
INSERT INTO t1 VALUES (1);
DELIMITER //
CREATE PROCEDURE simpleproc() begin select * from t1 into outfile 'into_outfile'; END //
DELIMITER ;

以mls身份登录

USE mls;
CALL simpleproc();

对于MariaDB，您需要SUPER权限：https://mariadb.com/kb/en/mariadb/documentation/sql-commands/data-manipulation/select-into-dumpfile/

procedure / outfile / prepared statement的权限
