解决向表中添加中文数据报错的问题

下面附上mysql的一些相关命令：

通过MySQL命令行修改:
　　set character_set_client=utf8;
　　set character_set_connection=utf8;
　　set character_set_database=utf8;
　　set character_set_results=utf8;
　　set character_set_server=utf8;
　　set character_set_system=utf8;
　　set collation_connection=utf8;
　　set collation_database=utf8;
　　set collation_server=utf8;
修改数据库字符集:
     ALTER DATABASE db_name DEFAULT CHARACTER SET character_name [COLLATE ...];
     如:
     ALTER TABLE test CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
     修改表的默认字符集:
     ALTER TABLE tbl_name DEFAULT CHARACTER SET character_name [COLLATE...];
     如：ALTER TABLE logtest DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
     修改字段的字符集:
     ALTER TABLE tbl_name CHANGE c_name c_name CHARACTER SET character_name [COLLATE ...];
     如：ALTER TABLE logtest CHANGE title title VARCHAR(100) CHARACTER SET utf8 COLLATE utf8_general_ci;
