A method, system and computer program product for retrieving data records to a client computer. An identifier of a base query is received from the client computer. The base query is configured to select a set of data records from a database that the client computer has permission to access. A modifying clause is also received from the client computer. The modifying clause comprises a directive restricting the set of data records to a subset of data records. The modifying clause may optionally comprise an expression for sorting. A combined query is generated from the base query and the modifying clause. The query is configured to return the subset of data records. The combined query is further configured to sort the subset of data records based on the value of the expression if the expression is present. The combined query is executed at the database.

System and method for filtering database results using dynamic composite queries

Resources are retrieved asynchronous through the use of resource requests to a feed server. When the feed server returns an initial requested resource, a URI for a next resource is sent to the requesting subscriber. The URI for the next resource was pre-generated by the feed server before the next resource was created, thus allowing the subscriber to have a pending asynchronous resource request at the feed server. This resource request persists on the feed server until the new resource becomes available.
