对多个 CTE 表执行一系列计算

Question

似乎无法弄清楚对我的查询执行一系列函数的公式。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 MINUS E0002，这个结果将永远是分母。在此之后，我需要将表格中的其他每一行都除以这个结果。

第 1 次 (2811-98)、第 2 次 E0013 (52/(2811-98)) 第 3 次 E0019 (405/(2811-98)) 第 4 次 E0004 (2256/(2811-98) 结束。

我已经尝试添加汇总和其他一些东西，我在这里看到了，但没有一个成功。

--下面的代码是您的代码从 CTE 到临时表的转换。 --希望您可以对其进行更好的诊断。只需评估您在上次查询中生成的每个数据。我认为UNION有点草率。你确定它真的是 UNION 而不是 UNION ALL？
