Custom Query Notifications

When I first saw SqlCacheDependancy and Query Notifications I was really stoked. I began using these features in ASP.NET and some of this caching really sped up my site. However, I noticed some of my queries and results were not cached. This led me on a looonnnnggggg search of the internet for anything related to these topics.

Anyway, the problem is that the queries are very limited (http://msdn2.microsoft.com/en-us/library/ms181122.aspx) in what they can contain, no count(*), no top, no order by, etc etc. I understand that the reason for this may be that the Query Notifications is using some of the Indexed Views infrastructure and therefore has the same limitations. That's fine and all but caching the results of these types of queries is still very useful for a front page of a site where you want the top ten users by number of postings etc and if you use the TOP N clause to limit it to the top 10 then you lose the built in caching functionality because this query doesn't work with Query Notifications and the cache expires immediately.

Is there a way to just get notifications when the tables involved in a query changes? I don't need the granular level of the rowsets involved I just want to be notified if my table has changed so I can refresh my cached objects.

I know there is an overload for the constructor of the SqlCacheDependency class which takes the database and table names as parameters. MSDN states that this is for Sql Server 7 and 2000 but would this also work in my scenerio? I know it wouldn't be auto-magical but if I can still get pushed notifications of changes instead of polling for notifications I would believe this to be a more efficient solution.

Query Notifications are fantastic but the query limitations make real world usage a pain, it's like have a nice red sports car but finding out you can only drive it whens it is raining and then you can only make right turns.

RegardsBTW, I'm using ASP.NET 2.0 and SQL Server 2005.
