Question

我遇到了一些有点奇怪的事情。我正在从Windows上的文件名运行我的查询

与source c:\sql\general.sql类似，但失败

mysql> source c:\sql\general.sql

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that

e c:ql' at line 1
    ->

此查询

CREATE TABLE mytable (
    id INT NOT NULL AUTO_INCREMENT,
    name varchar(50) NOT NULL,
    PRIMARY KEY (id)
);

但是，当我尝试运行相同的查询但这次命名我的文件stuff.sql

时

mysql> source c:\sql\stuff.sql
Query OK, 0 rows affected (0.65 sec)

这是一个常见错误吗？

更新

source c:\sql\\general.sql产生此错误

mysql> source c:\sql\\general.sql

Answer 1

使用正斜杠：

mysql> source c:/sql/general.sql

我永远不会原谅Microsoft使用元字符作为默认目录分隔符。

Answer 2

\g在MYSQL中用作输出格式字符。你需要双重逃避，例如

source c:\sql\\general.sql

是mysql中保留的文件名general.sql
