Question

I have the following CTE Query

;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

The Sort(Tree) Column has output like this (for two rows)…

2
1_2

Where, 2 is a Category TVs and 1_2 means this is tree map (1: Internet Tv, 2 = Jadoo Tv)

Now can I return the Category Name with the Category Code as well?

something like

2:Jadoo Tc

1_Internet Tv: 2_Jadoo Tv

Thanks

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