今天给大家介绍一下如何查询 mysql 的字符集。文章的内容丸趣 TV 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，下面跟着丸趣 TV 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;

39 rows in set (0.00 sec)3、查看库的字符集
语法：show create database 数据库 \G;
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
+-----------+--------+---------+------------+------+----------------+-------------------------+-------------+------------+-----------------+----------+-
| Name | Engine | Version | Row_format | Rows | Avg_row_length | Data_leate_time | Update_time | Check_time | Collation | Checksum |

+-----------+--------+---------+------------+------+----------------+-------------------------+-------------+------------+-----------------+----------+-
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 |
+-------+----------+-----------------+------+-----+---------+-------+---------------------------------+---------+
