MySQL字符集设置 系统变量： – character_set_server：默认的内部操作字符集 – character_set_client：客户端来源数据使用的字符集 – character_set_connection：连接层字符集 – character_set_results：查询结果字符集 – character_set_database：当前选中数据库的默认字符集 – character_set_system：系统元数据(字段名等)字符集 – 还有以collation_开头的同上面对应的变量，用来描述字符序。 登陆MySQL数据库: C:Usersduansf>mysql -u root -p Enter password: ****** Welcome to the MySQL monitor. Commands end with ; or g. Your MySQL connection id is 4 Server version: 5.5.13 MySQL Community Server (GPL) Copyright (c) 2000, 2010, Oracle and/or its affiliates. All rights reserved.

Type 'c' to clear the current input statement. mysql> 一.查看MySQL数据库服务器和数据库MySQL的字符集： mysql> show variables like '%char%'; +--------------------------+---------------------------------------------------------------+ | Variable_name | Value | +--------------------------+---------------------------------------------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | gbk | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | C:Program Files (x86)MySQLMySQL Server 5.5sharecharsets | +--------------------------+---------------------------------------------------------------+ 8 rows in set (0.00 sec) 二.查看MySQL数据表（table）的MySQL字符集: mysql> use test Database changed mysql> show table status from test like '%work%'; +----------+--------+---------+------------+------+----------------+-------------+-----------------+ --------------+-----------+----------------+---------------------+-------------+------------+------- ----------+----------+----------------+---------+ | Name | Engine | Version | Row_format | Rows | Avg_row_length | Data_length | Max_data_length | Index_length | Data_free | Auto_increment | Create_time | Update_time | Check_time | Collat ion | Checksum | Create_options | Comment | +----------+--------+---------+------------+------+----------------+-------------+-----------------+ --------------+-----------+----------------+---------------------+-------------+------------+------- ----------+----------+----------------+---------+ | workinfo | InnoDB | 10 | Compact | 1 | 16384 | 16384 | 0 | 32768 | 9437184 | 4 | 2016-03-07 16:13:51 | NULL | NULL | utf8_g eneral_ci | NULL | | | +----------+--------+---------+------------+------+----------------+-------------+-----------------+ --------------+-----------+----------------+---------------------+-------------+------------+------- ----------+----------+----------------+---------+ 1 row in set (0.00 sec) 三.查看MySQL数据列（column）的MySQL字符集: mysql> show full columns from workinfo; +----------+-------------+-----------------+------+-----+---------+----------------+---------------- -----------------+---------+ | Field | Type | Collation | Null | Key | Default | Extra | Privileges | Comment | +----------+-------------+-----------------+------+-----+---------+----------------+---------------- -----------------+---------+ | id | int(10) | NULL | NO | PRI | NULL | auto_increment | select,insert,u pdate,references | | | name | varchar(20) | utf8_general_ci | NO | | NULL | | select,insert,u pdate,references | | | type | varchar(10) | utf8_general_ci | YES | | NULL | | select,insert,u pdate,references | | | address | varchar(50) | utf8_general_ci | YES | | NULL | | select,insert,u pdate,references | | | tel | varchar(20) | utf8_general_ci | YES | | NULL | | select,insert,u pdate,references | | | wages | int(11) | NULL | YES | | NULL | | select,insert,u pdate,references | | | contents | tinytext | utf8_general_ci | YES | | NULL | | select,insert,u pdate,references | | | extra | text | utf8_general_ci | YES | | NULL | | select,insert,u pdate,references | | +----------+-------------+-----------------+------+-----+---------+----------------+---------------- -----------------+---------+ 8 rows in set (0.02 sec) 解决字符集通讯设置不匹配的方法： (修改默认的character_set_client,character_set_connection,character_set_result) 1. 重新编译mysql和php,mysql加入编译参数 –default-character-set=utf8 2. PHP程序在查询数据库之前，执行mysql_query(”set names utf8;”); 3.修改my.cnf，在[mysqld]中加入init-connect=”set names utf8” (对于超级用户连接该选项无效) 4. 启动mysqld 加入参数 –skip-character-set-client-handshake 忽略客户端字符集。 （编辑：大连站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
