ここに画像の説明を入力してください私は次のCTEクエリを持っています

;WITH cte AS (
    SELECT 0 AS lvl, id, catName, parent,
        CAST(id AS VARCHAR(128)) AS Sort
    FROM CategoriesMap WHERE id =2
    UNION ALL
    SELECT p.lvl + 1, c.id, c.catName, c.parent,
        CAST(CAST(c.id AS VARCHAR) + '_' + p.Sort   AS VARCHAR(128))
    FROM CategoriesMap c
    INNER JOIN cte p ON p.parent = c.id
)
select * from cte

Sort（Tree）列には、次のような出力があります（2行の場合）...

2
1_2

ここで、2はカテゴリTVであり、1_2これはツリーマップであることを意味します(1: Internet Tv, 2 = Jadoo Tv)

カテゴリコードとともにカテゴリ名を返すことはできますか？

何かのようなもの

2:Jadoo Tc

1_Internet Tv: 2_Jadoo Tv

ありがとう
