Question

似乎无法弄清楚在查询中执行一系列功能的公式。我需要根据STAT代码减去DIF列中的数字。在每种情况下，我都需要执行相同的一系列功能。 STAT I0099减E0002，此结果将始终是分母。之后，我需要将表中的其他所有行都除以该结果。

第一（2811-98），第二E0013（52 /（2811-98）），第三E0019（405 /（2811-98）），第四E0004（2256 /（2811-98）结束。

我曾尝试在此处添加汇总和其他几项内容，但均未成功。

-以下代码是您的代码从CTE到临时表的转换。 -希望您可以对其进行更好的诊断。只需评估您在上一个查询中生成的每个数据即可。我认为UNION有点草率。您确定它确实是一个UNION，而不是UNION ALL吗？
