Can you make a UNIQUE index on name in the staff_skills table?  If not you may not be able to create the foreign key constraint.

dear groups,
   i have a doubt in sql,
   i have a table staff_skills in which i have set a table level
constraint to create a primary key of two fields .
   so 'name' and 'skill' combinedly forms a primary key.
   now the issue is in another table i have only 'name' field and i want
to create a foreign key constraint which refers the staff_skills table's
'name' field only.
  staff_skills (table) - name,skill,ability  (columns)   ---  primary
key(name,skill)
  staff_xxxx (table) - name,x,y,z            (columns)  ---   foreign
key(name) references staff_skills(name).
  how to do the above?
  your immediate reply will be helpful
yours sincerely
