我真想知道这是什么

[Ice].entry(1,SalesRepList,'~')

如果它是一个函数，您可以处理它。但它似乎在创建常量值，而不是每行的动态值

我看到查询是由多个CTE表达式组成的

报告CTE由联合组成，如果可能，可以将其转换为联合所有

许多人分组计算

也许可以使用PARTITION BY子句使用SUM函数将这些语法转换为新的聚合语法，以简化查询的各个部分。例如，这一部分可以大大简化：

(case 
 when DatePart(month,Constants.Today) = 1 then Constants.FirstDayOfMonth
 when DatePart(month,Constants.Today) = 2 then DateAdd(month,-1,Constants.FirstDayOfMonth)
    when DatePart(month,Constants.Today) = 3 then DateAdd(month,-2,Constants.FirstDayOfMonth)
    when DatePart(month,Constants.Today) = 4 then DateAdd(month,-3,Constants.FirstDayOfMonth)
    when DatePart(month,Constants.Today) = 5 then DateAdd(month,-4,Constants.FirstDayOfMonth)
    when DatePart(month,Constants.Today) = 6 then DateAdd(month,-5,Constants.FirstDayOfMonth)
    when DatePart(month,Constants.Today) = 7 then DateAdd(month,-6,Constants.FirstDayOfMonth)
    when DatePart(month,Constants.Today) = 8 then DateAdd(month,-7,Constants.FirstDayOfMonth)
    when DatePart(month,Constants.Today) = 9 then DateAdd(month,-8,Constants.FirstDayOfMonth)
    when DatePart(month,Constants.Today) = 10 then DateAdd(month,-9,Constants.FirstDayOfMonth)
    when DatePart(month,Constants.Today) = 11 then DateAdd(month,-10,Constants.FirstDayOfMonth)
 else DateAdd(month,-11,Constants.FirstDayOfMonth)
 end) as [Calculated_BOY],

可能是

(case 
 when DatePart(month,Constants.Today) = 12 then Constants.FirstDayOfMonth
 else DateAdd(month, - ( DatePart(month,Constants.Today) - 1), Constants.FirstDayOfMonth) end ) as [Calculated_BOY]

b将子选择分离到临时表中，特别是那些您可以验证生成相对较小的结果集的表，比如说数千行或更少。将这些临时表提供给select而不是子select将有助于查询处理器

请简化查询。。。这是明智的建议。我认为您的查询太长，无法在这里得到有意义的答案。这是一个怪物查询！将其拆分并找出导致性能问题的原因。只有这样，我们才能提供帮助。看起来您正试图在一个查询中执行整个ETL过程。分解查询，使用视图并简化它。如果您最终在SELECT hugequery1、hugequery2等中组合了10个不同的查询，那么您做得不对谢谢！我用你的建议更新了我的问题，并将查看其余部分以尝试简化。就像我说的，我很擅长打破东西，如果没有你的帮助，我永远不会看到这一切。谢谢！除了一个工会外，我把所有工会都改成了全体工会。
