首先，这是一个我正在搞乱的项目管理数据库。所以我有 3 件事我想把JOIN一个planning_entity和两个子查询放在一起。这些子查询从树结构中分离出来。我想要的树结构部分是项目、阶段和活动。我需要项目的名称、阶段、阶段的开始和结束日期以及用于它们的时间。问题是，时间与活动有关，而日期是阶段。当我JOIN将这些放在一起时，它会拉起活动的结束日期，而我希望它NULL为阶段拉起，因为阶段尚未完成。

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

这目前让我知道活动的结束日期，而不是阶段的结束日期，有什么建议吗？
