c# - MySQL解释生成查询中的特殊字符

Question

我正在尝试使用 MySql.data.dll 将我们框架的数据库层从 SQLServer 迁移到 MySQL。我在 MySQL 中有以下生成的查询：

select * from `user` where `user_domainname` = 'domain\beth';

MySQL 将上述字符串中的 '\b' 解释为响铃字符，而 SqlServer 不解释任何此类转义字符。MySQL中的解决方案 -

select * from `user` where `user_domainname` = 'domain\\beth';

要在 C# 中执行此操作，我必须用 \b 替换每个 \b 或其他此类字符，考虑到我最终会进行的此类转换的数量，这对我来说不是一个非常可行的选择。

So my question is- Is there any option in MySQL to avoid it interpreting such special characters at the database level. If not what is there any api I can use to perform such a transformation. I did check out the MySqlHelper class but could not find anything useful there.

Thanks in advance,

Starting with MySQL 5.0.1, you can set NO_BACKSLASH_ESCAPES to turn the backslash into yet another ordinary character. Be sure you never rely on a backslash somewhere else though!

To do this on a live server (until it reboots):

SET GLOBAL sql_mode='NO_BACKSLASH_ESCAPES';

Don't forget to add it to your MySQL configuration file (my.cnf or my.ini) so it takes effect on the next startup! Add the line

sql-mode=NO_BACKSLASH_ESCAPE
