mysql - 无法删除触发器，因为它“不存在”
问题描述
我有以下两个触发器
cascadeUserInsertionToRecommendations_tbl
和
afterinsertiontousers
现在，为了完整起见，下面是“显示触发器”的结果；
+-------------------------------------------+--------+-----------+--------------------------------------------------------------------------------------------------------------------------------------------------------+--------+------------------------+-----------------------------------------------------+---------+----------------------+----------------------+--------------------+
| Trigger | Event | Table | Statement | Timing | Created | sql_mode | Definer | character_set_client | collation_connection | Database Collation |
+-------------------------------------------+--------+-----------+--------------------------------------------------------------------------------------------------------------------------------------------------------+--------+------------------------+-----------------------------------------------------+---------+----------------------+----------------------+--------------------+
| cascadeUserInsertionToRecommendations_tbl | INSERT | users_tbl | INSERT INTO recommendations_tbl(recommendation_userid, recommendation_category, recommendation_manufacturer) VALUES(NEW.user_id, 'diverse', 'diverse') | AFTER | 2019-09-02 12:32:46.19 | NO_ZERO_IN_DATE,NO_ZERO_DATE,NO_ENGINE_SUBSTITUTION | @ | latin1 | latin1_swedish_ci | latin1_swedish_ci |
| afterinsertiontousers | INSERT | users_tbl | INSERT INTO recommendations_tbl(recommendation_userid, recommendation_category, recommendation_manufacturer) VALUES(NEW.user_id, DEFAULT, DEFAULT) | AFTER | 2019-09-02 15:48:39.52 | NO_ZERO_IN_DATE,NO_ZERO_DATE,NO_ENGINE_SUBSTITUTION | @ | latin1 | latin1_swedish_ci | latin1_swedish_ci |
+-------------------------------------------+--------+-----------+--------------------------------------------------------------------------------------------------------------------------------------------------------+--------+------------------------+-----------------------------------------------------+---------+----------------------+----------------------+--------------------+
现在的问题是我不能删除它们：/当我在基础测试时，我创建触发器的数据库如下所示：
CREATE TRIGGER afterinsertiontousers
-> AFTER INSERT ON users_tbl
-> FOR EACH ROW
-> INSERT INTO recommendations_tbl(recommendation_userid, recommendation_category, recommendation_manufacturer) VALUES(NEW.user_id, DEFAULT, DEFAULT);
Query OK, 0 rows affected (0.016 sec)
这就是发生的事情：
MariaDB [foundationtests]> DROP TRIGGER users_tbl.cascadeUserInsertionToRecommendations_tbl;
ERROR 1360 (HY000): Trigger does not exist
我已经切换到 information_schema 数据库并在那里删除了上面的触发器。但是，它仍然出现在这里并且它仍然可以完成它不应该的工作......
我读到必须在 SO 上的多个其他线程上使用“db5”，但是当使用“显示数据库”时，我无法访问这个数据库，它也不会出现在我的数据库列表中；所以我对我想念的东西一无所知 Oo
