我有一个表（Equip，它是插入的），它有一个触发器，asset_tracker.dbo.EIS_JobAssetMaint用数据更新另一个表（ ）。如果我通过 SSMS 手动更新数据Equip，触发器会正确更新Maxtemp和RunHrs列asset_tracker.dbo.EIS_JobAssetMaint。

如果我Equip通过 C# 中的 Linq To Sql 代码进行编辑，Equip则会更新但asset_tracker.dbo.EIS_JobAssetMaint仅从触发器中部分更新。

ie 中的数据Equip是正确的，但是 2 列Maxtemp和Runtime，不要被转移到asset_tracker.dbo.EIS_JobAssetMaint列中，Maxtemp并且RunHrs

这是触发器：

希望这不会太令人困惑。如果是这样，请告诉我。

这是我对复杂触发器进行故障排除的提示。取出创建触发器部分并将插入或删除（或两者）更改为名为#inserted 或#deleted 的临时表。在运行扩孔脚本之前，创建#inserted 表并使用适合您需要测试的可能内容的测试数据填充它。现在您可以一次运行脚本的其余部分，并查看您尝试使用测试代码查找的内容的值。完成后，删除测试代码，将#inserted 更改回 insert 并放入 inteh 创建或更改触发器部分。
