可以使用trigger命令行关键字激活触发跟踪,这个关键字决定在发生事件时执行表2中的哪些操作。
The table WIP_FULL_ARCHIVE, is continuously growing in size since a trigger mechanism trickle-feed data into that archive table from the IWH.EDITION table.

The replication target (on the local system) would be a real table, so the trigger-based mechanism outlined in this article would work.
复制目标(在本地系统上)是一个真正的表,所以本文中描述的基于触发器的机制是可行的。
If an XML validation check constraint exists on the XML column of the table, the user may need to validate the new XML value before the update either manually or by creating a trigger.
如果在表的xml列上存在XML验证检查约束,在手动更新或者通过触发器更新之前,用户可能需要验证新的xml值。
