Subj:   Re: PI on multicolumns?
From:   frank.c.martinez

Working on Teradata since '94, and never seen anything about "should be defined only on a single column". And unique is a choice. It can be evenly distributed w/o being unique. I suggest that you might need some basic information on how PI's work.
