Postgresql Postgres-带递归-获取父名称列

我有一张桌子：

创建表格单元格
(
cellpk序列号不为空，
cellname字符不为空，
父整数不为空，
约束cellpk主键（cellpk）
)

---

尝试连接到原始表：

WITH RECURSIVE cell_child AS (
  SELECT fp.* FROM cell as fp WHERE fp.parent = '111'
  UNION ALL
  SELECT f.* FROM cell AS f
    JOIN cell_child as fc ON f.parent = fc.cellpk
 )     
 SELECT cc.*, parent.cellname
   FROM cell_child AS cc
   LEFT JOIN cell AS parent ON parent.cellpk = cc.parent;

subcellA1 - cellA subcellA2 - cellA subsubcellA1- subcellA1 subsubcellA2- subcellA2

WITH RECURSIVE cell_child AS (
  SELECT fp.* FROM cell as fp WHERE fp.parent = '111'
  UNION ALL
  SELECT f.* FROM cell AS f
    JOIN cell_child as fc ON f.parent = fc.cellpk
 )     
 SELECT cc.*, parent.cellname
   FROM cell_child AS cc
   LEFT JOIN cell AS parent ON parent.cellpk = cc.parent;
