title: Clustered Indexes without Primary key
body: <p>A <a href="http://www.simple-talk.com/sql/learn-sql-server/sql-server-index-basics/" rel="noreferrer">clustered index</a> stores the actual data rows at the leaf level of the index. Returning to the example above, that would mean that the entire row of data associated with the primary key value of 123 would be stored in that leaf node.</p>

  <p><strong>Question</strong> - in case the primary key does not exists and I set the <code>Name</code> column as clustered index. In this case, will the above statement becomes contradictory?</p>
