You can do this by coming up with 2 projects.
Project 1: polls for the new records, in your table of interest,and write to a temp table.
Project 2: (exposed as a Web service, takes an empty input). Whenever called will read all the records from the temp table and return them as output of the Web service. Further, delete all the records in the temp table after reading from it.
Mark the posting appropriately, as "helpful", "correct answer", if your issue is solved.
