本篇内容主要讲解“Mysql数据库怎么查看使用的编码”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“Mysql数据库怎么查看使用的编码”吧!
Mysql数据库默认编码
查看使用的编码
1. 使用status查看
mysql> status
--------------
mysql Ver 14.14 Distrib 5.6.44, for Linux (x86_64) using EditLine wrapper
2. 使用show variables
show variables like 'character'
mysql> show variables like 'character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
/etc/my.cnf文件中修改配置信息
使用默认的配置信息
本机访问自己的数据库:Server characterset: latin1
status
Server characterset: latin1
Db characterset: latin1
Client characterset: utf8
Conn. characterset: utf8
show variables like 'character%'
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
创建一个数据库encodtest,查看其编码信息
Server characterset: latin1
Db characterset: latin1
Client characterset: utf8
Conn. characterset: utf8
mysql> show variables like 'character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
character_set_database是数据库的编码格式创建一个test表查看其默认的编码格式
show create table test;
+-------+-------------------------------
| Table | Create Table |
+-------+-------------------------------
| test | CREATE TABLE `test` (
`id` int(11) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 |
+-------+-------------------------------
DEFAULT CHARSET=latin1默认的编码格式是latin1,与数据库编码格式相同
更改配置文件/etc/my.cnf添加设置:
[client]
default-character-set = utf8
[mysqld]
character-set-server=utf8
collation-server=utf8_unicode_ci
本机进入数据库查看编码格式:
status
Server characterset: utf8
Db characterset: utf8
Client characterset: utf8
Conn. characterset: utf8
show variables like 'char%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
创建数据库查看其编码与上面相同创建表查看编码:
+-------+------------------------------------------------------
| Table | Create Table |
+-------+------------------------------------------------------
| test | CREATE TABLE `test` (
`id` int(11) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci |
+-------+-----------------------------------------------------
DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci默认的编码格式与配置相同
到此，相信大家对“Mysql数据库怎么查看使用的编码”有了更深的了解，不妨来实际操作一番吧！
