Sql server SQL Server:删除字段后触发器不工作

--------已更新触发代码，请帮助-----------

我有一个触发器，当行被更新时，它会记录某些列上的任何更新。它工作得很好，直到我在表格中间删除了一个列。它现在只记录删除列之前的列，而不会记录删除列之后的任何列。我猜表中有某种排序列顺序？因此，当我删除一列时，它不会对列重新编号

为了演示正在发生的事情，假设我有这样的专栏：

字段1 字段2 字段3 字段4 然后，我在设计视图中打开了该表并删除了字段2，因此该表现在有：

字段1 字段3 字段4 在此之后，触发器仅捕获并记录Field1上的任何更新，而不是Field3和Field4。。。等等，这些都不起作用。这与更新的列有关，但在删除列后，我无法确定它是如何关闭的

知道发生了什么吗？我是否需要以某种方式重新编号列，以便触发器可以正常工作？提前谢谢

这是扳机。是的，这是一个大的，它工作得很好，但当我删除标题和ShippingAddressFlag之间的一列时。标题前的任何字段都有效，标题后的任何字段都无效，我认为它是关闭的，因为该字段已删除。也许与更新的索引有关，我不知道如何解决这个问题

如果您发布一些代码，这里会有更多的关注甚至答案。COLUMNS_UPDATED操作表中列的列索引-因此，是的，如果您删除一列，当然，您还必须在这里调整此模式，以适应新的现实，即列在表中的显示方式！如果没有触发代码，包括绑定详细信息的创建脚本，就没有机会获得答案…：很有可能简单地删除并重新创建触发器就可以解决问题。根据上面的说明，触发器只需要重新编译。
