员工组织结构图的T-SQL分层Json结果

我试图从SQLServer数据库中为公司组织结构图输出分层JSON

我想以类似的方式显示数据

我已经能够构建一个查询，将层次结构输出到一个平面表中，如下所示：

我能够通过使用FOR JSON PATH实现我想要的，但这只会真正为我提供一个层次结构所需的数据

有谁知道如何从T-SQL输出多个层次结构级别，以提供类似以下输出的内容：

 {
          'name': 'Lao Lao',
          'title': 'general manager',
          'children': [
            { 'name': 'Bo Miao', 'title': 'department manager' },
            { 'name': 'Su Miao', 'title': 'department manager',
              'children': [
                { 'name': 'Tie Hua', 'title': 'senior engineer' },
                { 'name': 'Hei Hei', 'title': 'senior engineer',
                  'children': [
                    { 'name': 'Pang Pang', 'title': 'engineer' },
                    { 'name': 'Xiang Xiang', 'title': 'UE engineer'
            'children': [
                {'name': 'Pang Pang2', 'title': 'engineer'},
                {'name': 'Pang Pang3', 'title': 'engineer'}
            ] 
            }
                  ]
                }
              ]
            },
            { 'name': 'Yu Jie', 'title': 'department manager' },
            { 'name': 'Yu Li', 'title': 'department manager' },
            { 'name': 'Hong Miao', 'title': 'department manager' },
            { 'name': 'Yu Wei', 'title': 'department manager' },
            { 'name': 'Chun Miao', 'title': 'department manager' },
            { 'name': 'Yu Tie', 'title': 'department manager' }
          ]
        }
      });

我已经尝试了好几个小时了，我还没有找到解决方案，网络上的任何东西似乎都帮不了我

谢谢

我找到了一篇非常好的文章，帮助我实现了我需要做的事情。 这不是最快的解决方案，但很有效

这本Microsoft指南也非常有用：

有了这两个指南，我能够构建出一些有效的东西，我仍然需要清理代码，但这里是我最后得到的，以防这对其他人有所帮助
