[英]SSRS AVG function with where clause

I have a question about the avg-function in SSRS/Report Builder. 我对SSRS /报表制作工具中的avg功能有疑问。 What I want to achieve is a expression which is giving a average of the lead time per incident which is taking the urgency of the incident in account. 我要实现的是一个表达式，它给出了每个事件的提前期的平均值，并考虑了事件的紧迫性。 I already made this simple expression for all the incidents which works fine: =Avg(Fields!Lead_time_call__in_days_.Value, "DataSet1") 对于所有正常工作的事件，我已经做了一个简单的表达： =Avg(Fields!Lead_time_call__in_days_.Value, "DataSet1")

This is the expression I made which should take the urgency in account (but which doesn't work): =AVG(IIF(Fields!Urgency.Value = "Low", Fields!Lead_time_call__in_days_.Value, 0), "DataSet1") 这是我制作的表达式，应该考虑到紧急性（但不起作用）： =AVG(IIF(Fields!Urgency.Value = "Low", Fields!Lead_time_call__in_days_.Value, 0), "DataSet1")

This displays this: screenshot But that's not possible, since the individual averages can't be all lower than the total average (which is correct) 这将显示以下内容：屏幕快照但这是不可能的，因为单个平均值不能全部低于合计平均值（正确）

Does anybody know what I'm doing wrong? 有人知道我在做什么错吗？ Thanks! 谢谢！

I fixed it! 我修好了它！ Thanks to @xcvd for helping. 感谢@xcvd的帮助。 I just had to replace the 0 with nothing . 我只需要将0替换为nothing 。 That acts as a NULL and doesn't messes up the calculation. 该行为为NULL ，不会使计算混乱。
