　　今天给大家介绍一下如何查询mysql的字符集。文章的内容小编觉得不错，现在给大家分享一下，觉得有需要的朋友可以了解一下，希望对大家有所帮助，下面跟着小编的思路一起来阅读吧。

　　方法：1、“show charset”语句，查看MYSQL所支持的字符集；2、“show create database 库名/G”语句，查看库的字符集；3、“show full columns from 表名”，查看表中所有列的字符集。

　　本教程操作环境：windows7系统、mysql8版本、Dell G3电脑。

　　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%';
　　方法一：

　　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)
　　方法二：

　　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)
　　2、查看MYSQL所支持的字符集

　　使用show charset可查看MYSQL所支持的字符集

　　mysql> show charset;
　　+----------+-----------------------------+---------------------+--------+
　　| Charset | Description                 | Default collation   | Maxlen |
　　+----------+-----------------------------+---------------------+--------+

　　+-----------+--------+---------+------------+------+----------------+-------------------------+-------------+------------+-----------------+----------+-
　　1 row in set (0.00 sec)
　　5、查看表中所有列的字符集

　　语法：show full columns from 表名;

　　mysql> show full columns from test_info;
　　+-------+----------+-----------------+------+-----+---------+-------+---------------------------------+---------+
　　| Field | Type     | Collation       | Null | Key | Default | Extra | Privileges                      | Comment |
