title: App Engine Datastore Viewer, how to show count of records using GQL?
body: <p>I would <em>think</em> this would be easy for an SQL-alike!  What I want is the GQL equivalent of:</p>
  
  <pre><code>select count(*) from foo;
  </code></pre>
  
  <p>and to get back an answer something similar to:</p>
  
  <pre><code>1972 records.
  </code></pre>
  
  <p>And I want to do this in GQL from the "command line" in the web-based DataStore viewer.  (You know, the one that shows 20 at a time and lets me see "next 20")</p>
  
  <p>Anyway -- I'm sure it's brain-dead easy, I just can't seem to find the correct syntax.  Any help would be appreciated.</p>
  
  <p>Thanks!</p>
