PHPSpreadsheet查询长度是否有限制？

Question

我已经创建了一些phpspreadsheet“报告”文件，并且所有这些都运行良好。我已经创建了第三个脚本，但是现在遇到了脚本无法完全运行的问题，现在我想知道PHP电子表格如何读取嵌套查询是否存在限制。

我首先像其他所有脚本一样从头开始创建脚本，然后将其放置一整夜以供运行，但是该脚本在经过很长的时间后就超时了，就像我已有的PHP / Mysql设置一样。

接下来，我尝试运行我现有的脚本之一，并且它像以前一样运行良好。

最后，我将其他报告之一的脚本复制到当前脚本中，以测试没有模板错误，并且该脚本也按预期运行。

我还只在MySQL工作台中运行查询，该查询在不到10秒的时间内返回了结果。

SQLFiddle：http://sqlfiddle.com/#!9/3c754eb/1

我已经添加了查询，并删除了嵌套表，只是为了查看查询本身。

UNION ALL (UNIONING THE TWO NESTED QUERIES)

LEFT JOIN

不幸的是，除了超时之外，没有错误代码，并且脚本会继续运行直到超时。
