 <h1 id="tutorial-querying-data">Tutorial: Querying data</h1>

 <p>This tutorial will demonstrate how to query data in Apache Druid (incubating), with examples for Druid&#39;s native query format and Druid SQL.</p>

 <p>The tutorial assumes that you&#39;ve already completed one of the 4 ingestion tutorials, as we will be querying the sample Wikipedia edits data.</p>

 <ul>
 <li><a href="../tutorials/tutorial-batch.html">Tutorial: Loading a file</a></li>
 <li><a href="../tutorials/tutorial-kafka.html">Tutorial: Loading stream data from Kafka</a></li>

 <li><a href="../tutorials/tutorial-tranquility.html">Tutorial: Loading stream data using Tranquility</a></li>
 </ul>

 <h2 id="native-json-queries">Native JSON queries</h2>

 <p>Druid&#39;s native query format is expressed in JSON. We have included a sample native TopN query under <code>quickstart/tutorial/wikipedia-top-pages.json</code>:</p>
 <div class="highlight"><pre><code class="language-json" data-lang="json"><span></span><span class="p">{</span>

   <span class="p">]</span>
 <span class="p">}</span>
 </code></pre></div>
 <p>This query retrieves the 10 Wikipedia pages with the most page edits on 2015-09-12.</p>

 <p>Let&#39;s submit this query to the Druid Broker:</p>
 <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span></span>curl -X <span class="s1">&#39;POST&#39;</span> -H <span class="s1">&#39;Content-Type:application/json&#39;</span> -d @quickstart/tutorial/wikipedia-top-pages.json http://localhost:8082/druid/v2?pretty

 <h2 id="druid-sql-queries">Druid SQL queries</h2>

 <p>Druid also supports a dialect of SQL for querying. Let&#39;s run a SQL query that is equivalent to the native JSON query shown above:</p>
 <div class="highlight"><pre><code class="language-text" data-lang="text"><span></span>SELECT page, COUNT(*) AS Edits FROM wikipedia WHERE &quot;__time&quot; BETWEEN TIMESTAMP &#39;2015-09-12 00:00:00&#39; AND TIMESTAMP &#39;2015-09-13 00:00:00&#39; GROUP BY page ORDER BY Edits DESC LIMIT 10;
 </code></pre></div>
 <p>The SQL queries are submitted as JSON over HTTP.</p>

 <h3 id="topn-query-example">TopN query example</h3>

 <p>The tutorial package includes an example file that contains the SQL query shown above at <code>quickstart/tutorial/wikipedia-top-pages-sql.json</code>. Let&#39;s submit that query to the Druid Broker:</p>
 <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span></span>curl -X <span class="s1">&#39;POST&#39;</span> -H <span class="s1">&#39;Content-Type:application/json&#39;</span> -d @quickstart/tutorial/wikipedia-top-pages-sql.json http://localhost:8082/druid/v2/sql
 </code></pre></div>
 <p>The following results should be returned:</p>
 <div class="highlight"><pre><code class="language-json" data-lang="json"><span></span><span class="p">[</span>
