title: google big query limit clause returning too many rows
body: <p>In big query I am running a query on exported tables from GA.</p>
  
  <p>I can not seem to get big query to limit the results. Here is a sample query, quite basic.</p>
  
  <pre><code>SELECT * FROM [1111111.ga_sessions_20140318] LIMIT 20000
  </code></pre>
  
  <p>The result set returns but with 7 million+ rows! I have tried this several different ways, ie. out to a table, just return result set, use cache results, don't use cached results, etc.
  No matter which table I try to query it always returns the entire table. </p>
  
  <p>This is basically the same as the sample query big query gives when clicking on the query table button except I changed the limit value from 1000 to 20000.</p>
  
  <p>Anyone have any insight?</p>
