sql-获取2个子查询的最小值,sql,sql-server,subquery,min,Sql,Sql Server,Subquery,Min,我有一个查询，它有5个子查询。我需要它只有4个子查询，因为其中两个子查询应该只有一个结果。问题是我不知道如何维护查询结构并获取其中2个子查询的最小值。这是我的疑问： Select Artigo, Descricao, sum(Stock) as Stock, Sum(QuantidadeEmEncomendasPendentes) as QuantidadeEmEncomendasPendentes, Sum(Stock) - Sum(QuantidadeEmEncomendasPendente

我需要得到第3和第4个子查询的最小值，而不是将它们都添加到主查询的总和（Stock）。我怎样才能做到这一点？我需要维护查询结构。。我需要这些查询结果的最小值（第三和第四）：

只需先将它们合并在一起，找到最小值，然后将结果与其他子查询合并。@EzLo如何？我已经试了好几天了，但似乎不可能。我无法更改查询结构，因为它需要从“不同角度”计算所有股票。。我的工作很差劲，没法让它工作。。我只需要一个查询来获得这两个子查询的最小值，但它需要位于主查询IDN上，我不知道这些CTE。谢谢冻糕，你没有给我确切的我需要的，但我终于得到了解决方案感谢你的帮助听起来不错！是的，与子查询相比，CTE允许您定义一次结果集，并在任何地方重用，甚至在其他CTE内部。
