Question

当我在cmd中尝试此命令时：

SOURCE D:\books.sql;

我收到此错误：

错误：无法打开文件'D：\ books.sql;'，错误：2

我在网上搜索了这个，到目前为止我发现这个错误不知何故意味着没有这样的文件或目录！但我很确定我的档案就在那里！感谢。

这是books.sql中的代码：

DROP DATABASE IF EXISTS books;

CREATE DATABASE books;

USE books;

所以在中间我没有用分号测试它，这是结果：

ERROR 1010 (HY000): Error dropping database (can't rmdir '.\books\', errno: 17)

似乎因为第1行而发生此错误。现在做什么？

Answer 1

既然你已经自己回答了“来源问题”，我会尝试帮助第二部分。

内部mysql数据库由目录表示，在此目录中由数据库文件表示。现在，当您删除数据库时，mysql首先删除文件，最后一步将删除该目录。

现在有两种情况可能导致错误17：

该目录的权限不足
不受mysql管理的剩余文件

所以我会执行以下步骤：首先检查您对该目录的权限，如果您确定它们没问题，请尝试再次运行您的示例。如果这不起作用，请检查目录path/to/mysql/books中是否有与mysql无关的文件并手动删除它们。在此之后，您应该能够执行DROP DATABASE IF EXISTS books;命令。

mysql source命令给出错误2和错误17？
