</code></pre><div class="line-numbers" aria-hidden="true"><div class="line-number"></div></div></div><p>我们可以使用 SHOW DATABASES 语句来查看系统当前所有的 database，SQL 语句如下：</p><div class="language-text line-numbers-mode" data-ext="text" data-title="text"><pre class="language-text"><code>IoTDB&gt; SHOW DATABASES
</code></pre><div class="line-numbers" aria-hidden="true"><div class="line-number"></div></div></div><p>执行结果为：</p><div class="language-text line-numbers-mode" data-ext="text" data-title="text"><pre class="language-text"><code>+-------------+
