Report of Filters and what they are referenced by

Hi All,

I am looking for orphaned filters which are no longer being used.    I can find these manually by opening the filter and going to the bottom section of filter membership and choosing Referenced By.   From there I can see if the filter is being used by anything and then chose to get rid of it.

So far I have found filters with this SQL

select * from vNonResourceItem where ClassGuid = 'AECA2D91-C615-4D99-BAD5-612CA159DA4F' and Attributes = 0

I can work my way around in SQL but I am struggling to find the right table which has this relationship.

Any suggestions?  better yet has anyone else needed this same report and has already created it?
