t-sql recursive query

Question

Based on an existing table I used CTE recursive query to come up with following data. But failing to apply it a level further.

Data is as below

id    nam         


        

Answer 1

Something like

;WITH MyCTE AS
(
    SELECT
        name AS FullPaths, id
    FROM
        MyTable
    WHERE
        parentid  = 0 /*Normally it'd be IS NULL with an FK linking the 2 columns*/
    UNION ALL
    SELECT
        C.FullPaths + '\' + M.name, M.id
    FROM
        MyCTE C
        JOIN
        MyTable M ON M.parentid = C.id
)
SELECT FullPaths FROM MyCTE
