2. comparing two ResultSet    coderanch.com

What you describe is a way to locate any record in a resultset based on column values. Short of iterating through all records and comparing the column values searching for the match I don't see another solution. However, I'd probably run a query searching just for the desired column values. Much better than bringing all of the table from the database ...

CLOSE_CURSORS_AT_COMMIT - well, the resultset is closed when you commit and you cannot read from it anymore. There is not much more ...
