在MySQL中执行函数时，SELECT命令被拒绝

Question

当我尝试选择功能时

SELECT myDatabase.myFunction('');

我收到错误

ERROR 1142 (42000): SELECT command denied to user 'myUser'@'localhost' for table 'myTable'

虽然用户拥有所有权限

mysql> show grants for myUser;
+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Grants for myUser@%                                                                                                                                                            |
+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'myUser'@'%' IDENTIFIED BY PASSWORD ''                                                                                                                   |
| GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, LOCK TABLES, EXECUTE, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE ON `myDatabase`.* TO 'myUser'@'%'|
+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

我也可以直接访问myTable而没有任何问题。

任何帮助将不胜感激。

P.S。所有功能，表格，数据库，用户名都可以，以防我在这篇文章中拼写错误。

尝试GRANT ALL;可能缺少功能许可
