Question

首先，这是一个我正在搞乱的项目管理数据库。所以我想要JOIN一起planning_entity和两个子查询。这些子查询分离了树结构。我想要的树结构部分是Project，Phase和Activity。我需要项目的名称，阶段，阶段的开始和结束日期，以及专门用于它们的时间。问题是，小时数是与活动相关联的，日期是相位。当我JOIN这些在一起时，它会拉出活动的结束日期，因为相位尚未完成，我希望它为相位提取NULL。

示例代码：

SELECT  MIN(spp.Project) AS 'Project', spp2.Phase
, FORMAT(MIN(stp.actual_start), 'd', 'en-US') AS 'Actual Start', FORMAT(MIN(stp.actual_finish), 'd', 'en-US') AS 'Actual Finish'
, FORMAT(MAX(effort_actual) + MAX(effort_reserved) + MAX(effort_required) + MAX(effort_scheduled) , 'N', 'en-us') AS 'Forecast Effort'
, FORMAT((MAX(baseline_allocated_effort) + MAX(baseline_reserved_effort) + MAX(baseline_required_effort)) , 'N', 'en-us') AS 'Baseline Effort'
, FORMAT(MAX(effort_actual), 'N', 'en-us') AS 'Effort Actual'
FROM ip.planning_entity stp 
LEFT JOIN (SELECT ips.father_code
        , (SELECT ips2.description 
            FROM ip.structure ips2
            WHERE depth = 5 AND ips2.structure_code = ips.father_code) AS 'Project'
        , ips.description AS 'Activity'
    FROM ip.structure ips
    WHERE ips.depth = 6) AS spp ON spp.father_code = stp.ppl_code
LEFT JOIN (SELECT ips.structure_code
        , (SELECT ips2.description 
            FROM ip.structure ips2
            WHERE depth = 6 AND ips2.structure_code = ips.father_code) AS 'Phase'
        , ips.description AS 'Activity'
    FROM ip.structure ips
    WHERE ips.depth = 7) AS spp2 ON spp2.structure_code = stp.planning_code
LEFT JOIN ip.vw_ppm_cube_fact f on f.ppl_code = stp.ppl_code
WHERE stp.ppl_code in   
     (SELECT structure_code FROM ip.portal_filter WHERE filter_code = 83686 and usage='EX')
GROUP BY spp2.Phase

这是目前从活动而不是阶段，任何建议的结束日期？
