Subj:   Re: Row CheckSum
 
From:   Victor Sokovin

  Of course hashrow(1,'a') is the same as hashrow('a', 1), but  


          > hashrow(col1) || hashrow(col2) || hashrow(col3) || hashrow(col4)
  or  


          > hashrow(hashrow(col1) || hashrow(col2) || hashrow(col3) || hashrow(col4))
  will avoid that.  


It certainly will but will it avoid hash collisions?


Season's greetings.
