Answer Posted / eshwari
ur question is not clear.
if ur saying that ur giving unique and not null constraints
to the same column then u can make it as primary key.it
internally supports clustered index also.
if ur saying that ur giving unique and not null constraints
to different columns then u cant make them as primary key
individually.
coz primary key means unique + notnull + clustered index
