title: Does making a primary key in multiple columns generate indexes for all of them?
body: <p>If I set a primary key in multiple columns in Oracle, do I also need to create the indexes if I need them?</p>
  
  <p>I believe that when you set a primary key on <strong>one</strong> column, you have it indexed by it; is it the same with multiple column PKs?</p>
  
  <p>Thanks</p>
