<h3 id="Asterisk13Function_DB_DELETE-Synopsis">Synopsis</h3>

<p>Return a value from the database and delete it.</p>

<h3 id="Asterisk13Function_DB_DELETE-Description">Description</h3>

<p>This function will retrieve a value from the Asterisk database and then remove that key from the database. <code>DB_RESULT</code> will be set to the key's value if it exists.</p>

                    <p class="title">Note</p>

<p>If <code>live_dangerously</code> in <code>asterisk.conf</code> is set to <code>no</code>, this function can only be read from the dialplan, and not directly from external protocols. It can, however, be executed as a write operation (<code>DB_DELETE(family, key)=ignored</code>)</p>
