title: Bigquery INSERT after WITH AS statement not working
body: <p>I have a CTE like this:</p>
  <pre><code>WITH source1 as (
  SELECT blah FROM blah
  ), source2 as (
  SELECT moreblah FROM source1)
  
  SELECT * FROM source2;
  </code></pre>
  <p>I want to insert the results of this query into a table, but when I write this:</p>
  <pre><code>WITH source1 as (
  SELECT blah FROM blah
  ), source2 as (
  SELECT moreblah FROM source1)
  
  INSERT INTO newtable SELECT * FROM source2;
  </code></pre>
  <p>It says I have a syntax error <code>Expected &quot;(&quot; or &quot;,&quot; or keyword SELECT but got keyword INSERT</code>. I'm wondering if this is a Bigquery issue b/c I've looked at other places like <a href="https://stackoverflow.com/questions/3306096/combining-insert-into-and-with-cte">this</a> which say my INSERT INTO should work. Any help would be appreciated!</p>
