title: Vertica identity column datatype change
body: <p>In vertica I want to change the datatype of the identity column. For example</p>
  
  <pre><code>CREATE TABLE t1(x IDENTITY(1) ,y INT)
  </code></pre>
  
  <p>Is there a way to change the identity column incremental value from 1 to say 10000.</p>
  
  <p>I create the above table now I increment the identity column <code>x IDENTITY(1)</code> to <code>x IDENTITY(10000)</code></p>
  
  <p>I tried below sql but it does not work</p>
  
  <pre><code>alter table t1  alter column x SET DATA TYPE IDENTITY  ( 10000 );
  </code></pre>
