我必须创建一个报告，显示组织的监督关系层次结构。可以通过多种不同的方式设置监控线路。下面是其中的一些。

Vice President-Associate VP-Director-Assistant Director-Supervisor-worker
Vice President-Associate VP-Director-Supervisor - worker
Vice President-Director-Assistant Director-Supervisor-worker
Vice President-Director-worker
Vice President-Director-Director B-Worker
Vice President-Director-Director B-Supervisor->Worker
Vice President-Associate VP-worker
Vice President-worker
Vice President-Director-Assistant Director
Vice President-Director-worker

这些是层次结构中每个角色的表；所以，一个VP表，AVP表，Director表等等。如果层次结构线不包含某个角色，则该值应返回 null。我编写了程序，所以我从 Worker 表开始，然后从那里加入所有表。我试图考虑所有可能的连接（参见下面的程序）。我使用Supervisor_Position_NBR=POSITION_NBR使用不同的连接组合线条看起来有很多不同的方式，下面是一个小例子：

副总裁 副总裁_副总裁 董事 B 副总裁 _董事 监事 工人 ============== ============ ======== ======= === ===================================简·史密斯乔·罗伯茨马西·詹姆斯·空·空·詹姆斯·马雷·马特·G
·简Smith Joe Roberts Marcy James Null Null James Mare Jess D Jane Smith Joe Roberts Marcy James Null Null Frank jay Carol R Jane Smith Null Marty Bob Null Sonja Null Sam Smith Jane Smith Null Marty Bob Null Sonja Null Nate lowe Jane Smith Null Null Null Null Null拉尔夫·科尔

我的两个问题是：

  1. 当我有一条包含 VP 、 Director 和 Worker 的监督线，但主管和工作人员都直接向 VP 报告时，当查询运行时，Director 下线，只有工作人员显示。所以这：

副总裁 副总裁 副总裁 董事 B 副董事 主管 工人
=============== =========== ======= ======== == ================= ================= Jane Smith 空 空 空 空 空 空 MarcyJames

当我应该带回这个时：

副总裁 副总裁 副总裁 董事 B 副董事 主管 工人
============= =========== ======== ======== == ======== ======= ========= ===== Jane Smith Null Null Null Null Marcy James
Jane Smith Null Joe Roberts Null Null Null Null

  1. 有没有更干净更有效的方法来编写这个查询？

非常感谢任何帮助。

考虑一个公共表表达式，如下所示......

WITH org AS 
(
    SELECT 
        ee.POSITION_NBR, ee.EmpName, ee.Title
    FROM 
        employee AS ee
    UNION ALL 
    SELECT ee.POSITION_NBR, o.EmpName, o.Title
    FROM 
    employee AS ee 
    JOIN org o ON (o.POSITION_NBR = ee.SupervisorId)
)

SELECT * FROM org WHERE (POSITION_NBR IN (SELECT POSITION_NBR FROM employee where title = 'Worker'))

对于每个工人，此递归 CTE 检索工人管理链中的所有员工。

然后，您可以使用它并对其进行 PIVOT，以获得您想要的格式。缺少的管理级别将自动在其中具有 NULL 值。

查看此 SQL Fiddle以获取完整示例。为简洁起见，我只包括了前三个管理级别，但您应该能够按照此模式添加其他管理级别。
