如何检查特定 MySQL 数据库中所有表的字符集以及列名？

mysql> Select Column_name, TABLE_NAME, CHARACTER_SET_NAME FROM
       INFORMATION_SCHEMA.Columns Where TABLE_SCHEMA = 'db_name';

mysql> Select Column_name 'Column',TABLE_NAME, CHARACTER_SET_NAME FROM INFORMATION_SCHEMA.Columns Where TABLE_SCHEMA = 'Alpha';

+---------+------------+--------------------+
| Column  | TABLE_NAME | CHARACTER_SET_NAME |
+---------+------------+--------------------+
| Name    | employee   | latin1             |
| email   | employee   | latin1             |
| Name    | student    | latin1             |
| RollNo  | student    | NULL               |
| Address | student    | latin1             |
