原文如下:
问: 如果密码中包含反斜线,该如何处理呢?
答: 在mysql中,反斜线"\"是有特殊意义的,用于转义,因此如果密码中包含"\",就需要特别注意。有一种一劳永逸的办法,就是在密码中不用反斜线,哈哈。另一种,那就是需要多加几个反斜线,例如:
(root:hostname:Thu Oct 15 09:15:38 2009)[mysql]> grant usage on *.* to yejr@localhost identified by 'ye\\\jr';
Query OK, 0 rows affected (0.02 sec)
(root:imysql.cn:Thu Oct 15 09:16:22 2009)[mysql]> select password('ye\jr');
+-------------------------------------------+

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

(root:imysql.cn:Thu Oct 15 09:23:32 2009)[mysql]> select host,user,password from user where user='yejr';

从上面的例子可以看到,如果密码中有反斜线,就需要在它前面再加2个反斜线。
