I have two queries within access. Query 1 - contains all accounts that have been opened from Jan 1 - Dec 31, 2010. Query 2 contains all accounts opened from Jan 1 2010 - March 15 2011. Is there a way to identify the new accounts that have been opened? Those that are new will not be duplicated on Query 2. Is there a way to determine which ones have not been duplicated?
