MySQL查看与修改字符集的方法实例教程

一、查看字符集

1.查看MYSQL数据库服务器和数据库字符集

方法一:show variables like '%character%';

方法二:show variables like 'collation%';

mysql> show variables like '%character%';
+--------------------------+--------------------------------------+
| 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/local/mysql5535/share/charsets/ |
+--------------------------+--------------------------------------+
8 rows in set (0.00 sec)

方法一:
mysql> show variables like 'collation%';
+----------------------+-----------------+
| Variable_name  | Value   |
+----------------------+-----------------+
| collation_connection | utf8_general_ci |
| collation_database | utf8_general_ci |
| collation_server  | utf8_general_ci |
+----------------------+-----------------+
3 rows in set (0.00 sec)

方法二:

2.查看MYSQL所支持的字符集

show charset;

mysql> show charset;

查看MYSQL所支持的字符集

3.查看库的字符集

语法:show database status from 库名 like  表名;

mysql> show create database shiyan\G
*************************** 1. row ***************************
  Database: shiyan
Create Database: CREATE DATABASE `shiyan` /*!40100 DEFAULT CHARACTER SET gbk */
1 row in set (0.00 sec)

4.查看表的字符集

语法:show table status from 库名 like  表名;

mysql> show table status from class_7 like 'test_info';

mysql> show table status from class_7 like 'test_info';
+-----------+--------+---------+------------+------+----------------+-------------------------+-------------+------------+-----------------+----------+-
| Name  | Engine | Version | Row_format | Rows | Avg_row_length | Data_leate_time   | Update_time | Check_time | Collation  | Checksum | 
+-----------+--------+---------+------------+------+----------------+-------------------------+-------------+------------+-----------------+----------+-
| test_info | InnoDB |  10 | Compact | 10 |   1638 |  17-12-05 19:01:55 | NULL  | NULL  | utf8_general_ci |  NULL | 
+-----------+--------+---------+------------+------+----------------+-------------------------+-------------+------------+-----------------+----------+-
1 row in set (0.00 sec)
