oracle失败触发验证

Question

想象一下有2个触发器，例如

create or replace TRIGGER A AFTER CREATE ON SCHEMA

和

create or replace TRIGGER B AFTER CREATE ON SCHEMA

（关于模式的注释）。两者都是无效的（执行失败），您需要删除它们。

如果您尝试删除触发器A，则会得到：

An error was encountered performing the requested operation:

ORA-04098: trigger 'USER.B' is invalid and failed re-validation
04045. 00000 -  "errors during recompilation/revalidation of %s.%s"
*Cause:    This message indicates the object to which the following
           errors apply.  The errors occurred during implicit
           recompilation/revalidation of the object.
*Action:   Check the following errors for more information, and
           make the necessary corrections to the object.
Vendor code 4045

反之亦然。

您如何删除触发器？
