需要使用来自一个查询的信息来指示对另一个查询的操作

Question

好的，这听起来有点复杂。我想以某种方式放置某种函数，当它的策略号与另一个表中的策略号匹配时，将表值除以2。 这是我想要那些函数的查询

这是包含我想要的政策号码的qry在上面的qry中除以2。

SELECT 
qryReinsuranceDPA1.POLICY_NO, 
qryReinsuranceDPA1.PHASE_CODE, 
qryReinsuranceDPA1.SUB_PHASE_CODE, 
qryReinsuranceDPA1.ProdType, 
TotalDPA = Sum(case when [SumOfNetDefExtraAdj] Is Null then [SumOfNetDefPremiumAdj] else [SumOfNetDefPremiumAdj] + SumOfNetDefExtraAdj end), 
Sum(1) AS Expr1
FROM qryPolicyListforNYDefPRemAsset_Re RIGHT JOIN qryReinsuranceDPA1
ON 
qryReinsuranceDPA1.POLICY_NO = qryPolicyListforNYDefPRemAsset_Re.POLICY_NO AND 
qryReinsuranceDPA1.PHASE_CODE= qryPolicyListforNYDefPRemAsset_Re.PHASE_CODE AND 
qryReinsuranceDPA1.SUB_PHASE_CODE = qryPolicyListforNYDefPRemAsset_Re.SUB_PHASE_CODE 
GROUP BY qryReinsuranceDPA1.POLICY_NO, 
qryReinsuranceDPA1.PHASE_CODE, 
qryReinsuranceDPA1.SUB_PHASE_CODE, 
qryReinsuranceDPA1.ProdType
HAVING (((Sum(1))<>1))

GO

快速举例。假设策略号064543200位于第二个qry的结果中。然后，我想要将与该政策编号相关的总DPA中的第一个qry中的数字除以2。

如果这仍然令人困惑，请告诉我，我会尝试更好地解释。两者都是观点。
