                             DbUtils utils,
                             java.lang.String query,
                             int rows,

    `utils` - the DbUtils instance that connected to the DB
    `query` - the query that is the basis for the resultset
    `rows` - the maximum number of rows to retrieve (0 for all)
    `rs` - the ResultSet that was produced (depending on the type of SQL query it can also be NULL)
    `ex` - in case an exception occurred
