<p>You can assign ID to each request.</p>
<p>The ID can be used by canceling the request. See also
<a class="reference internal" href="../commands/request_cancel.html"><span class="doc">request_cancel</span></a> for details about canceling
a request.</p>
<p>Request ID should be managed by user. If you assign the same ID for
some running requests, you can’t cancel the request.</p>
<p>The simplest ID sequence is incremented numbers such as <code class="docutils literal notranslate"><span class="pre">1</span></code>,
<code class="docutils literal notranslate"><span class="pre">2</span></code> , <code class="docutils literal notranslate"><span class="pre">...</span></code>.</p>
<p>A request ID is a string. The maximum request ID size is 4096 byte.</p>

<p>All commands accept <code class="docutils literal notranslate"><span class="pre">request_id</span></code> parameter. You can assign ID to
request by adding <code class="docutils literal notranslate"><span class="pre">request_id</span></code> parameter.</p>
<p>Here is an example to assign <code class="docutils literal notranslate"><span class="pre">id-1</span></code> ID to a request:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>select Users --request_id id-1
