Answer 1

聚合是根据GROUP BY语句计算的，它们告诉数据库要聚合哪些行。 在大方案中，这是在执行WHERE子句之后发生的。 您必须先过滤可用的行， 然后才能对它们进行分组。

您没有为我提供足够的代码来提供具体的解决方案。 但是，有两种方法可以避免此问题。 使用HAVING子句，或在where子句中使用子查询。

HAVING子句的使用方式与WHERE但是它按照处理顺序在GROUP BY之后。 它可以执行以下操作：获取25岁以上的拥有十个以上用户的所有用户类型：

SELECT users.type
FROM users
WHERE users.age > 25
GROUP BY users.type
HAVING count(users.id) > 10

不幸的是，SQL的设计方式使子句在书面查询中出现的顺序与它们执行的顺序不太吻合。 这是造成混乱的常见原因，尤其是在别名方面。 您可以在这里阅读有关处理逻辑顺序的更多信息： http : //www.jooq.org/doc/3.0/manual/sql-building/sql-statements/select-statement/select-lexical-vs-logical-order/ 。

编辑：

我认为解决方案实际上要简单得多。 您的第二个外部联接是您提出spcgrp2字段的地方。 在其余查询中，您仅使用scpgrp2字段的总和。 因此，只需在子查询中对其求和即可。

您的第二个左外部连接变为

Left outer Join
    (Select grp2.customershipto,
      Sum(Case
           When grp2.spcgroup = 'SPC01' THEN 1
           when grp2.spcgroup = 'SPC02' THEN 2
           when grp2.spcgroup = 'SPC03' THEN 3
           when grp2.spcgroup = 'SPC04' THEN 4
           when grp2.spcgroup = 'SPC05' THEN 5
           when grp2.spcgroup = 'SPC06' THEN 6
           when grp2.spcgroup = 'SPC07' THEN 7
          END) spcgrp2_sum
     From ARCustomerSHIPTOSPCGroup grp2
     Group By grp2.customershipto
    ) tgrp

然后用Sum(tgrp.spcgrp2)将两行更改为

  When tgrp.spcgrp2_sum = 28 and cst.customertype = 'IND' THEN 'Correct'
  when tgrp.spcgrp2_sum = 25 and cst.customertype = 'ENG' THEN 'Correct'

Answer 2

只是让您以Tab Alleman提到的方式开始：

(Case WHEN (select Sum(tgrp.spcgrp2) from tgrp) = 28 and cst.customertype = 'IND' THEN 'Correct' ELSE 'Look Into' END) = 'Look Into'

Answer 3

正如其他人所指出的那样，您不能在WHERE子句中引用聚合函数。 这就是HAVING目的。

另外，很少有充分的理由在WHERE子句中使用CASE 。 您应该考虑将其转换为布尔逻辑。 我相信以下将完成您正在尝试的事情：

WHERE  cst.status = 'Active'
--Your GROUP BY clause goes here
HAVING    NOT (   (cst.territory = 200 AND cst.territory = grp.territory)
               OR (substring (grp.territory, 2, 3) = cst.territory))
       OR NOT (   (SUM (tgrp.spcgrp2) = 28 AND cst.customertype = 'IND')
               OR (SUM (tgrp.spcgrp2) = 25 AND cst.customertype = 'ENG')
               OR (cst.territory = 200))
