| </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"><pre class="language-text"><code>IoTDB> 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"><pre class="language-text"><code>+-------------+ |

| IoTDB> CREATE TIMESERIES root.ln.wf01.wt01.temperature WITH DATATYPE=FLOAT, ENCODING=RLE |
| </code></pre><div class="line-numbers" aria-hidden="true"><div class="line-number"></div><div class="line-number"></div></div></div><p>为了查看指定的时间序列，我们可以使用 SHOW TIMESERIES <Path>语句，其中、<Path>表示时间序列对应的路径，默认值为空，表示查看系统中所有的时间序列。下面是两个例子：</p><p>使用 SHOW TIMESERIES 语句查看系统中存在的所有时间序列，SQL 语句如下：</p><div class="language-text line-numbers-mode" data-ext="text"><pre class="language-text"><code>IoTDB> SHOW TIMESERIES |
