Question

我想选择与查询相关的最大值，但所有结果都将到来。有什么想法吗？

QUERY

SELECT MAXRecID,MAXSetID,MAXRID,PreReifiedValue,ComplianceState
FROM v_CI_CurrentComplianceStatus as A
INNER JOIN v_CIRules as B
ON B.CI_ID = A.CI_ID
INNER JOIN v_R_System  as C
ON C.ResourceID = A.ItemKey
INNER JOIN 
 ( SELECT PreReifiedValue,setting_CI_ID,
      MAX(RecordID) AS MAXRecID,
      MAX(SettingID) AS MAXSetID,
      MAX(RuleID) AS MAXRID
   FROM CI_CurrentRuleDetail
   GROUP BY PreReifiedValue,Setting_CI_ID,instancedata
 ) AS D
ON D.Setting_CI_ID = A.CI_ID
GROUP by MAXRecID,MAXSetID,MAXRID,PreReifiedValue,rulename,ComplianceState

结果

MAXRecID            MAXSetID    MAXRID  PreReifiedValue ComplianceState
72057594038117564   16780566    16780622    10                2
72057594038117565   16780570    16780620     0                2

尝试此查询

    SELECT 
       MAX(tmp.MAXRecID), MAX(tmp.MAXSetID), MAX(tmp.MAXRID), MAX(tmp.PreReifiedValue), MAX(tmp.ComplianceState)
    FROM (
    SELECT MAXRecID,MAXSetID,MAXRID,PreReifiedValue,ComplianceState
    FROM v_CI_CurrentComplianceStatus as A
    INNER JOIN v_CIRules as B
    ON B.CI_ID = A.CI_ID
    INNER JOIN v_R_System  as C
    ON C.ResourceID = A.ItemKey
    INNER JOIN 
     ( SELECT PreReifiedValue,setting_CI_ID,
          MAX(RecordID) AS MAXRecID,
          MAX(SettingID) AS MAXSetID,
          MAX(RuleID) AS MAXRID
       FROM CI_CurrentRuleDetail
       GROUP BY PreReifiedValue,Setting_CI_ID,instancedata
     ) AS D
    ON D.Setting_CI_ID = A.CI_ID
    ) AS tmp
    GROUP by tmp.MAXRecID, tmp.MAXSetID, tmp.MAXRID, tmp.PreReifiedValue, tmp.rulename, tmp.ComplianceState
