能在本地数据库为db_link里的表建trigger不?或用什么方法可实现
rt
[解决办法]
Statements inside a trigger can reference remote schema objects. However, pay special attention when calling remote procedures from within a local trigger. If a timestamp or signature mismatch is found during execution of the trigger, then the remote procedure is not run, and the trigger is invalidated.

可以通过dblink建trigger,但一旦网络有问题可能造成两边的数据都不能插入进去
