I'm not very familiar with MS SQL Server, but it appears to have  
something called "Query Notifications":

"allows an application to request a notification from SQL Server when  
the results of a query change. Query notifications allow programmers  
to design applications that query the database only when there is a  
change to information that the application has previously retrieved"
