逆轉'With Recursive'語句

Question

我有ff。查詢顯示董事的層次結構下，任何人：

WITH RECURSIVE emptree AS (
     SELECT e.win_id, 
      e.full_name, 
      e.current_sup_name, 
      e.sbu, 
      e.cost_center, 
      e.lob, 
      0 AS depth 
      FROM app_reports.vw_hiearchy e 
      WHERE e.win_id = xxxxxxx AND e.attrition_date IS NULL 
     UNION ALL 
     SELECT e.win_id, 
      e.full_name, 
      e.current_sup_name, 
      e.sbu, 
      e.cost_center, 
      e.lob, 
      t.depth + 1 AS depth 
      FROM app_reports.vw_hiearchy e 
      JOIN emptree t ON t.win_id = e.current_sup_win 
      WHERE e.attrition_date IS NULL 
     ) 
SELECT emptree.win_id, 
    emptree.full_name, 
    emptree.current_sup_name, 
    emptree.sbu, 
    emptree.cost_center, 
    emptree.lob, 
    emptree.depth 
    FROM emptree; 

，直到我請求增加另一個列（或以上），以顯示誰是一個特定的監督員（技術上添加列動態監事它工作正常 - 如果可能的話，那從下往上顯示所有主管）。我不確定是否需要顛倒這一點，才能從底層開始實際獲取層次結構，並將其顯示爲current_sup_name_2，current_sup_name3等等。但我不知道如何。

在此先感謝您的任何建議。 :)

應該可以顯示監事單場中完整的層次有一個小的修改現有的查詢：

WITH RECURSIVE emptree AS (
     SELECT e.win_id, 
      e.full_name, 
      e.current_sup_name, 
      e.sbu, 
      e.cost_center, 
      e.lob, 
      0 AS depth 
      FROM app_reports.vw_hiearchy e 
      WHERE e.win_id = xxxxxxx AND e.attrition_date IS NULL 
     UNION ALL 
     SELECT e.win_id, 
      e.full_name, 
      concat_ws(',', e.current_sup_name, t.current_sup_name) current_sup_name, 
      e.sbu, 
      e.cost_center, 
      e.lob, 
      t.depth + 1 AS depth 
      FROM app_reports.vw_hiearchy e 
      JOIN emptree t ON t.win_id = e.current_sup_win 
      WHERE e.attrition_date IS NULL 
     ) 
SELECT emptree.win_id, 
    emptree.full_name, 
    emptree.current_sup_name, 
    emptree.sbu, 
    emptree.cost_center, 
    emptree.lob, 
    emptree.depth 
    FROM emptree;
