推荐答案
我认为-的行为就像算术运算符，并且此RowFilter认为last和updated是两个不同的列，您尝试计算它们的差.
I think - acts like an arithmetic operator in your case and this RowFilter thinks that last and updated as a two different columns and you try to calculate their differences.
只需将它们用[]包装为[last-updated]就可以了.
Just wrap them with [] as [last-updated] in it should be fine.
