title: Column not found with CTE query on H2
body: <p>I am trying to understand how cte works but can't solve column not found error.</p>
  <p>This is my table:</p>
  <pre><code>CREATE TABLE IF NOT EXISTS NODE (UUID VARCHAR NOT NULL, PARENT_UUID VARCHAR NULL,
  NAME VARCHAR NOT NULL, PRIMARY KEY (UUID));
  </code></pre>
  <p>This is my query:</p>
  <pre><code>WITH tree AS
  (
      -- Anchor member
      SELECT * FROM node WHERE uuid = ''
      UNION ALL
      -- Recursive member that references expression_name.
      SELECT a.uuid, a.parent_uuid, a.name FROM node a
      INNER JOIN tree b ON b.parent_uuid = a.uuid
  )
  -- references expression name
  SELECT * FROM tree;
  </code></pre>
  <p>And this is what I get: <code>Column &quot;B.PARENT_UUID&quot; not found</code>. Could anyone help me?</p>
