title: nvarchar and nclob with db2 9.7
body: <p>The db2 9.7 sql reference clearly states that <code>nvarchar</code> and <code>nclob</code> datatypes are synonyms of <code>vargraphic</code> and <code>dbclob</code>, respectively (link <a href="http://publib.boulder.ibm.com/infocenter/db2luw/v9r7/index.jsp?topic=/com.ibm.db2.luw.sql.ref.doc/doc/r0057004.html" rel="nofollow">here</a>)</p>
  
  <p>Yet, when I write a simple create table statement, it doesn't work with <code>nvarchar</code> and <code>nclob</code> - I get an error message about unknown tokens. When using <code>vargraphic</code> and <code>dbclob</code> as is well.</p>
  
  <p>Any idea why?</p>
