Question

很确定它必须与MAX有关，但不确定如何解决此问题...。选择失败。 3504：（-3504）选定的非聚合值必须是关联组的一部分。任何反馈/建议/协助表示赞赏。试图为大型设备（30k +）的各种维护计划收集完成工作的最后日期。我很难找到适合自己的问题以进行搜索。

Answer 1

“选择”中未聚合的列与“分组依据”中列出的列不匹配。您可以将选择项中的所有内容（LastCompleted除外）添加到分组依据，也可以从选择项中删除一堆列：

select
  EQUIPMENT,
  MAX(LastCompleted) as CDATE
from
--your subquery here
where STATUS in ('I','IDLE')
  and DDATE is Null
  and PMTYPE in ('V','F')
  and "CHECKS" in ('YES')
group by
  EQUIPMENT

Answer 2

如果您只想每LastCompleted使用最新的EQUIPMENT行，请应用RANK / ROW_NUMBER：

SELECT
    SE.EquipmentSurfaceAssetBK AS "MRC",
    SE.EquipmentCodeBK AS "EQUIPMENT",
    SE.EquipmentDescription AS "DESCRIPTION",
    SE.EquipmentClassBK AS "CLASSCODE",
    SE.EquipmentCriticality AS "CRITICALITY",
    SE.EquipmentCostCode AS "COSTCODE",
    SE.EquipmentStatus AS "STATUS",
    PE.EqPMCodeBK AS "PM",
    PM.PMDescription AS "PMDESCRIPTION",
    PE.EqPMDueDate AS "NEXTDUE",
    PE.EqPMType AS "PMTYPE",
    PE.EqPMDeactivatedDate AS "DDATE",
    PE.EqPMAssignedBy AS "ASSIGNEDBY",
    PE.EqPMAssignedToResourceBK AS "ASSIGNEDTO",
    PE.EqPMFrequency AS "FREQUENCY",
    PE.EqPMFrequencyUOM AS "UOM",
    WO.WorkOrderEquipmentcodeBK AS "WOEQUIP",
    WO.WorkOrderCodeBK AS "WORKORDER",
    WO.WorkOrderPMCodeBK AS "WORKORDERPM",
    CASE
        WHEN WO.WorkOrderPMCodeBK = PE.EqPMCodeBK THEN 'YES' ELSE 'NO'
    END AS "CHECKS",
    WO.WorkOrderStatus AS "WOSTATUS",
    WO.WorkOrderCompletedDate AS "LastCompleted"
FROM IDW_PL_SURFACE.DIMSurfaceEquipment SE 
JOIN IDW_PL_SURFACE.DIMEquipmentPM PE
  ON SE.EquipmentCodeBK = PE.EqPMEquipmentCodeBK
JOIN IDW_PL_SURFACE.DIMSurfacePM PM
  ON PE.EqPMCodeBK = PM.PMCodeBK
JOIN IDW_PL_SURFACE.DIMWorkOrder WO
  ON SE.EquipmentCodeBK = WO.WorkOrderEquipmentcodeBK
WHERE 1=1
  AND STATUS IN ( 'I', 'IDLE')
  AND DDATE is Null
  AND PMTYPE IN (  'V', 'F')
  AND "CHECKS" IN ( 'YES')

QUALIFY RANK() OVER (PARTITION BY EQUIPMENT ORDER BY LastCompleted) = 1

尝试通过子查询执行MAX时出现Teradata错误3504
