Continuous querying continuously returns events that match the queries you set up.
Clients subscribe to server-side events by using SQL-type query filtering. The server sends all events that modify the query results. CQ event delivery uses the client/server subscription framework.

This topic discusses CQ management options, CQ states, and retrieving initial result sets.
