Sql 递归CTE-行数有限

我试图在一个非常简单的表上创建一个查询

我有专栏

Organisation, Manager, Superior_Organisation
CEO
Leadership Team, David, CEO 
Production Management, Alex, Leadership Team
Production Site 1, Francoise, Production Management
Production Site 2, Steve, Production Management
Production Site 1 Maintenance, Alan, Production Site 1

由于级别不同，我不知道如何创建一个查询，从一个特定级别开始向我提供所有上级组织

我试过这个密码

declare @i int
select @i = 0
-- keep going until no more rows added
while @@rowcount > 0
begin
select @i = @i + 1
-- Get all children of previous level
SELECT     organisations.Organisation, organisations.Manager,  
organisations.Superior_Organisation
FROM         organisations 
end

但是通过这个查询，我得到了所有信息，我不知道如何只查询上级组织，例如生产现场1维护。可以是1或最多5

一种可能是加入到谈判桌上，但我认为，这还远远不够

我见过一些递归CTE查询，但我不熟悉。非常感谢您的帮助。

这太棒了，速度太快了！我测试过了，它真的很有效。谢谢你，马丁
