但是如果你已经建了库和表可以通过以下方式进行查询。
1.查看默认的编码格式:
| mysql> show variables like "%char%"; +--------------------------+---------------+ | 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 | +--------------------------+-------------+ |
注：以前2个来确定,可以使用set names utf8,set names gbk设置默认的编码格式;
执行SET NAMES utf8的效果等同于同时设定如下：
| SET character_set_client='utf8'; SET character_set_connection='utf8'; SET character_set_results='utf8'; |
2.查看test数据库的编码格式:
| mysql> show create database test; +------------+------------------------------------------------------------------------------------------------+ | Database | Create Database | +------------+------------------------------------------------------------------------------------------------+ | test | CREATE DATABASE `test` /*!40100 DEFAULT CHARACTER SET gbk */ | +------------+------------------------------------------------------------------------------------------------+ |
3.查看yjdb数据表的编码格式:
| mysql> show create table yjdb; | yjdb | CREATE TABLE `yjdb` ( `sn` int(5) NOT NULL AUTO_INCREMENT, `type` varchar(10) NOT NULL, `brc` varchar(6) NOT NULL, `teller` int(6) NOT NULL, `telname` varchar(10) NOT NULL, `date` int(10) NOT NULL, `count` int(6) NOT NULL, `back` int(10) NOT NULL, PRIMARY KEY (`sn`), UNIQUE KEY `sn` (`sn`), UNIQUE KEY `sn_2` (`sn`) ) ENGINE=MyISAM AUTO_INCREMENT=1826 DEFAULT CHARSET=gbk ROW_FORMAT=DYNAMIC | |
二、避免导入数据有中文乱码的问题
1:将数据编码格式保存为utf-8
设置默认编码为utf8：
set names utf8;
设置数据库db_name默认为utf8:
| ALTER DATABASE `db_name` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci; |
设置表tb_name默认编码为utf8:
| ALTER TABLE `tb_name` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci; |
导入：
LOAD DATA LOCAL INFILE 'C:utf8.txt' INTO TABLE yjdb;
2:将数据编码格式保存为ansi(即GBK或GB2312)
设置默认编码为gbk：
set names gbk;
设置数据库db_name默认编码为gbk:
| ALTER DATABASE `db_name` DEFAULT CHARACTER SET gbk COLLATE gbk_chinese_ci; |
设置表tb_name默认编码为gbk:
| ALTER TABLE `tb_name` DEFAULT CHARACTER SET gbk COLLATE gbk_chinese_ci; |
