求助：Mysql命令行查询时，中文字段不显示

Question

今天用Mysql，突然发现Mysql命令行查询时，中文字段不显示，mysql能插入中文(可在Navicate中看到插入的中文字段),在命令行查询时，就是显示不出中文字段。以前都没出现过这种情况。求助各位高手，怎么解决啊？帮帮忙吧？我已经把数据库test、表中字段name、my.ini文件中都设置为GBK了，win7 32位系统。问题如下：mysql> use test;
Database changed
mysql> create table t(
    -> id int primary key,
    -> name varchar(20),
    -> age int);

Answer 1

set names gbk; 后再试试

Answer 2

set names 'gbk';字符集设置的问题。http://blog.csdn.net/ACMAIN_CHM/archive/2009/05/12/4174186.aspx
MySQL 中文显示乱码

Answer 3

show variables like 'char%';
set names 'gbk';

Answer 4

再帮忙看看，还有哪个地方有问题。mysql> show variables like 'char%';

Answer 6

你的字符集查询的时候是正确无误。 估计是写入的时候没有设置正确导致表中实际存放的并不是GBK的数据。
可以直接插入一条，然后检查。

Answer 7

varchar可以单独设定字符集的，可以查看下是否是这个问题。
