MYSQL：在子查询

Question

我有很长的MySQL查询它建立一个报表字段“顶级查询”未知的，这个问题我已经是顶级域“a.id”未知仅向副查询之一，这个查询是从“select with alias”中选择的。我在下面的评论（突出显示）之间设置了违规部分。如何获得子查询中识别的顶级字段？

请注意，除非高亮选择查询工作正常，但迄今仍未得到“增强”为提高效率，这是第一个快速运行做POC报告。

进一步说明我已经删除了所有公司敏感数据和缩进以帮助我“阅读部分中的查询”，除了所有部分仍然应该链接起来形成功能查询，（再次：禁止违规选择）。 :-)

我建议修改违规的部分是这样的：

IFNULL(
    (
    /*select SUM(bandwreq * mplsterm) 
    from (*/ 
     select /*compa_memusersoft.acron,*/ SUM(compa_memusersoft.bandwreq * compa_memconndetails.mplsterm)
