我们如何才能只看到特定 MySQL 数据库中存储函数的列表？

mysql> SELECT ROUTINE_TYPE, ROUTINE_NAME FROM INFORMATION_SCHEMA.ROUTINES WHERE ROUTINE_SCHEMA = 'query' AND ROUTINE_TYPE = 'FUNCTION'//
+--------------+--------------------+
| ROUTINE_TYPE | ROUTINE_NAME       |
+--------------+--------------------+
| FUNCTION     | factorial          |
| FUNCTION     | Hello              |
+--------------+--------------------+
