</code></pre> <div class="line-numbers-wrapper"><span class="line-number">1</span><br></div></div><p>执行成功后，Cli/Shell返回execute successfully表示执行成功。</p> <p>存储组设定后，使用CREATE TIMESERIES语句可以创建新的时间序列，创建时间序列时需要定义数据的类型和编码形式。SQL语句如下：</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>IoTDB&gt; CREATE TIMESERIES root.ln.wf01.wt01.status WITH DATATYPE=BOOLEAN, ENCODING=PLAIN
</code></pre> <div class="line-numbers-wrapper"><span class="line-number">1</span><br></div></div><p>执行成功后，Cli/Shell返回execute successfully表示执行成功。
如果系统中已有被创建的存储组和时间序列，则系统会提示该部分已存在。如以下提示表示存储组已存在：</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>IoTDB&gt; SET STORAGE GROUP TO root.ln

</code></pre> <div class="line-numbers-wrapper"><span class="line-number">1</span><br><span class="line-number">2</span><br></div></div><p>创建时间序列后，我们使用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- line-numbers-mode"><pre class="language-text"><code>IoTDB&gt; SHOW TIMESERIES
