HashRow will not give you the "row uniqueness" portion of the row-id. The SQL that Qaisar posted merely counts the rows currently in the table for a given row hash value and does not give you a row uniqueness value for each individual row. The only way that I know of to get the uniqueness value for a particular row as Rajgopal asked is to use one of the system console utilities such as Filer to perform a dump of the physical row.
