MySQL字符集多种多样，下面为您列举了其中三种最多见的MySQL字符集查看方法，该方法供您参考，但愿对您学习MySQL数据库能有所启迪。mysql
1、查看MySQL数据库服务器和数据库MySQL字符集。sql
mysql>showvariableslike'%char%';
+--------------------------+-------------------------------------+------
|Variable_name|Value|......
+--------------------------+-------------------------------------+------
|character_set_client|utf8|......--客户端字符集
|character_set_connection|utf8|......
|character_set_database|utf8|......--数据库字符集
|character_set_filesystem|binary|......
|character_set_results|utf8|......
|character_set_server|utf8|......--服务器字符集
|character_set_system|utf8|......
|character_sets_dir|D:\MySQLServer5.0\share\charsets\|......
+--------------------------+-------------------------------------+------
2、查看MySQL数据表(table)的MySQL字符集。数据库
mysql>showtablestatusfromsqlstudy_dblike'%countries%';
+-----------+--------+---------+------------+------+-----------------+------
|Name|Engine|Version|Row_format|Rows|Collation|......
+-----------+--------+---------+------------+------+-----------------+------
|countries|InnoDB|10|Compact|11|utf8_general_ci|......
+-----------+--------+---------+------------+------+-----------------+------
3、查看MySQL数据列(column)的MySQL字符集。服务器
mysql>showfullcolumnsfromcountries;
+----------------------+-------------+-----------------+--------
|Field|Type|Collation|.......
+----------------------+-------------+-----------------+--------
|countries_id|int(11)|NULL|.......
|countries_name|varchar(64)|utf8_general_ci|.......
|countries_iso_code_2|char(2)|utf8_general_ci|.......
|countries_iso_code_3|char(3)|utf8_general_ci|.......
|address_format_id|int(11)|NULL|.......
+----------------------+-------------+-----------------+--------
修改单个表的字符集：学习
ALTER TABLE tbl_name CONVERT TO CHARACTER SET charset_name;
修改数据库中全部表的字符集：rest
SELECT concat('alter table ', table_name, ' CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;') FROM information_schema.tables WHERE table_schema='替换你的数据库名称' and table_collation != 'utf8_general_ci' GROUP BY table_name;code
修改完毕后重启数据库：orm
sudosystemctl restart mariadbserver
