在“连接属性”的设置中，高级-“使用mysql字符集”去掉钩，并且将编码改为10008-GB2312.
然后进入navicat的控制台后，show variables like ‘char%’;命令后如下:
+————————–+—————————————+
| Variable_name            | Value                                 |
+————————–+—————————————+
| character_set_client     | latin1                                |
| character_set_connection | latin1                                |
| character_set_database   | utf8                                  |
| character_set_filesystem | binary                                |
| character_set_results    | latin1                                |
| character_set_server     | utf8                                  |
| character_set_system     | utf8                                  |
| character_sets_dir       | D:\mysql-5.1.32-win32\share\charsets\ |

此时我们需要在控制台运行 set names ‘gbk’命令，运行后再次show variables like ‘char%’;命令查看结果如下：

+————————–+—————————————+
| Variable_name            | Value                                 |
+————————–+—————————————+
| character_set_client     | gbk                                   |
| character_set_connection | gbk                                   |
| character_set_database   | utf8                                  |
| character_set_filesystem | binary                                |
| character_set_results    | gbk                                   |
| character_set_server     | utf8                                  |
| character_set_system     | utf8                                  |
| character_sets_dir       | D:\mysql-5.1.32-win32\share\charsets\ |

客户端连接环境设置算是完成了。接着中文数据该怎么插还是怎么插，不会再有乱码出现。

至于从.sql.txt等文本批量导入数据，则需要将相应的文件转化为gbk格式保存再导入，否则导入后会乱码
