文档解释

ORA-30509: client logoff triggers cannot have AFTER type

Cause: An attempt was made to create a trigger that fires after logoff. This type of trigger is not supported.

Action: Do not attempt to create a trigger that fires after logoff.

ORA-30509消息通知用户无法在客户端断开时使用AFTER触发器。

官方解释

ORA-30509表明客户端断开事件不能与AFTER触发器一起使用，因为客户端断开事件表示会话已关闭，而AFTER触发器将在会话关闭之后触发。

常见案例

如果用户尝试在客户端断开连接时添加AFTER触发器，则会触发此错误。

一般处理方法及步骤

1.检查客户端断开连接触发器的代码，确保不使用AFTER触发器。

2.更改客户端断开连接触发器的代码，使用BEFORE触发器。

3.重新编译触发器。

4.重试操作以解决此问题。
