<p>有时你一个数据集可能只用一个SQL查询还不够，比如你需要一个清单数据，同时你需要一个汇总数据做为说明在图形中显示，这样你就需要使用多条SQL语句，在数据集中的写法你只需要用分号隔开，如：</p>
<div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;"><code class="language-javascript" data-lang="javascript"><span style="display:flex;"><span><span style="color:#75715e">//数据集中的查询
</span></span></span><span style="display:flex;"><span><span style="color:#75715e"></span><span style="color:#a6e22e">select</span> ... <span style="color:#a6e22e">from</span> <span style="color:#a6e22e">xxx</span>;
</span></span><span style="display:flex;"><span><span style="color:#a6e22e">select</span> ..... <span style="color:#a6e22e">from</span> <span style="color:#a6e22e">xxxxxxx</span>
</span></span><span style="display:flex;"><span>
</span></span><span style="display:flex;"><span><span style="color:#75715e">// 传递到图形中的格式为:
</span></span></span><span style="display:flex;"><span><span style="color:#75715e"></span>{<span style="color:#e6db74">&#34;df0&#34;</span><span style="color:#f92672">:</span>[[...]]. <span style="color:#e6db74">&#34;df1&#34;</span><span style="color:#f92672">:</span>[[......]]}
</span></span><span style="display:flex;"><span><span style="color:#a6e22e">df0</span>, <span style="color:#a6e22e">df1分别对应的是第一段和第二段查询</span>
</span></span></code></pre></div><p>
