mysql字符集编码错误的导入数据会提示错误了,这个和插入数据一样如果保存的数据与mysql编码不一样那么肯定会出现导入乱码或插入数据丢失的问题,下面我们一起来看一个例子。

<script>ec(2);</script>

恢复数据库报错:由于字符集问题,最原始的数据库默认编码是latin1,新备份的数据库的编码是utf8,因此导致恢复错误。

[root@hk byrd]# /usr/local/mysql/bin/mysql -uroot -p'admin' t4x < /tmp/11x-B-2014-06-18.sql ERROR 1064 (42000) at line 292: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''[caption id=/"attachment_271/" align=/"aligncenter/" width=/"300/"]<a href=/"ht' at line 1

修复方法(未实测):
