query data in Apache Druid using SQL.  </p><p>It assumes that you&#x27;ve completed the <a href="/docs/latest/tutorials/">Quickstart</a>
 or one of the following tutorials, since we&#x27;ll query datasources that you would have created
 by following one of them:</p><ul><li><a href="/docs/latest/tutorials/tutorial-batch">Load a file</a></li><li><a href="/docs/latest/tutorials/tutorial-kafka">Load stream data from Kafka</a></li><li><a href="/docs/latest/tutorials/tutorial-batch-hadoop">Load a file using Hadoop</a></li></ul><p>There are various ways to run Druid SQL queries: from the web console, using a command line utility
 and by posting the query by HTTP. We&#x27;ll look at each of these. </p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="query-sql-from-the-web-console">Query SQL from the web console<a href="#query-sql-from-the-web-console" class="hash-link" aria-label="Direct link to Query SQL from the web console" title="Direct link to Query SQL from the web console"></a></h2><p>The web console includes a view that makes it easier to build and test queries, and
 view their results. </p><ol><li><p>Start up the Druid cluster, if it&#x27;s not already running, and open the web console in your web
 browser. </p></li><li><p>Click <strong>Query</strong> from the header to open the Query view:  </p><p><img loading="lazy" alt="Query view" src="/assets/images/tutorial-query-01-255bc08f1f43198a74d6e0b51ba63b34.png" title="Query view" width="1250" height="640" class="img_ev3q"></p><p>You can always write queries directly in the edit pane, but the Query view also provides
 facilities to help you construct SQL queries, which we will use to generate a starter query. </p></li><li><p>Expand the wikipedia datasource tree in the left pane. We&#x27;ll
 create a query for the page dimension.  </p></li><li><p>Click <code>page</code> and then <strong>Show:page</strong> from the menu: </p><p><img loading="lazy" alt="Query select page" src="/assets/images/tutorial-query-02-ba5ead6e542013d5312417a810009ef7.png" title="Query select page" width="1250" height="640" class="img_ev3q"></p><p>A SELECT query appears in the query edit pane and immediately runs. However, in this case, the query
 returns no data, since by default the query filters for data from the last day, while our data is considerably
 older than that. Let&#x27;s remove the filter.  </p></li><li><p>Click <strong>Run</strong> to run the query.</p><p>You should now see two columns of data, a page name and the count:</p><p><img loading="lazy" alt="Query results" src="/assets/images/tutorial-query-03-3bb6a7521f4fcc9bf410ab6bfa1fa63f.png" title="Query results" width="1250" height="640" class="img_ev3q"></p><p>Notice that the results are limited in the console to about a hundred, by default, due to the <strong>Smart query limit</strong>
 feature. This helps users avoid inadvertently running queries that return an excessive amount of data, possibly
 overwhelming their system. </p></li><li><p>Let&#x27;s edit the query directly and take a look at a few more query building features in the editor.
 Click in the query edit pane and make the following changes: </p><ol><li><p>Add a line after the first column, <code>&quot;page&quot;</code> and Start typing the name of a new column, <code>&quot;countryName&quot;</code>. Notice that the autocomplete menu suggests column names, functions, keywords, and more. Choose &quot;countryName&quot; and
 add the new column to the GROUP BY clause as well, either by name or by reference to its position, <code>2</code>.  </p></li><li><p>For readability, replace <code>Count</code> column name with <code>Edits</code>, since the <code>COUNT()</code> function actually
 returns the number of edits for the page. Make the same column name change in the ORDER BY clause as well. </p><div class="codeBlockContainer_Ckt0 theme-code-block" style="--prism-color:#bfc7d5;--prism-background-color:#292d3e"><div class="codeBlockContent_biex"><pre tabindex="0" class="prism-code language-text codeBlock_bY9V thin-scrollbar"><code class="codeBlockLines_e6Vv"><span class="token-line" style="color:#bfc7d5"><span class="token plain">  The `COUNT()` function is one of many functions available for use in Druid SQL queries.
