当这是一个附加的触发器时，insert和update上的linqto -sql失败

I am having some problems with linq-to-sql lately. The problem is that it “thinks” that it fails on inserts and updates when we have a trigger attached to the event. An example could be a row, where a trigger is attached to set the “LastUpdated” colon to the current time, when a row is altered. This will cause linq-to-sql to think that is have failed on the update or insert, but this is only some times, as it sometimes go through, I think this is when the sql server is under heavy load and where therefore not able to execute the trigger before the validation was made, this is only speculation. As my scripts are only a part of a much bigger script, so disabling the trigger is not an option, so I need to find a solution to this, or rewrite my program. Have any of you experienced this problem and have found a solution, for example disabling validation after inserts? I am having some problems with linq-to-sql late
