title: BigQuery _TABLE_SUFFIX for ga_sessions
body: <p>This query works fine...</p>
  
  <pre><code>SELECT page.* FROM `zentinel-datawarehouse.xxx.ga_sessions_20170601` ga,
  UNNEST (hits) hits,
  UNNEST (hits.page) page
  </code></pre>
  
  <p>but when i need use _table_suffix</p>
  
  <pre><code>SELECT page.* FROM `zentinel-datawarehouse.xxx.ga_sessions_*` ga,
  UNNEST (hits) hits,
  UNNEST (hits.page) page
  WHERE _TABLE_SUFFIX&gt;=20170601
  </code></pre>
  
  <p>Dont works any more...</p>
  
  <p>This happened in thats date because hits.page is record repeteabled... in month 08 or 09 works fine because is record NULL
  ANY IDEA???</p>
  
  <p>REGARDS</p>
