我有一个“reslookup”表,我想在其中选择向另一个reportingid报告的员工。
以下是我的表的简化版本,包含以下内容:
Emp_NO Name ReportingID
531 A 16
1572 B 531
1032 C 1572
and so..on..
Now, If I select ReportingID = 16 (in where condition), then Employees 531,1572,1032 should fetch,
Similarly, If I select ReportingID = 531 (in where condition), then Employees 1572,1032 should fetch,
Similarly, If I select ReportingID = 1572 (in where condition), then Employees 1032 should fetch
有什么解决办法吗??
最佳答案
下面的代码对您有帮助,
select Emp_No, Name, ReportingID
from Reslookup as t1
where ReportingID = 16
or exists
( select *
from Reslookup as t2
where Emp_No = t1.ReportingID
and
(
ReportingID = 16
or exists
(
select *
from Reslookup as t3
where Emp_No = t2.ReportingID
and ReportingID = 16
)
)
)
你必须通过,这里我给你16分。所以这将返回三行。
