[Bug?] Recurrent CTE results are wrong (2)

[hiroyuki0415]

The following is a recursive CTE that recursively retrieves the parent (3 layers) of [businessunit]:

WITH     cte
AS       (SELECT NULL AS [child],
                 e0.logicalname AS [parent],
                 e0.logicalname AS [path],
                 0 AS [depth]
          FROM   metadata.entity AS e0
          WHERE  e0.logicalname IN ('businessunit')
          UNION ALL
          SELECT rs.referencingentity AS [child], --(※1)
                 --cte.parent AS [child], (※2)
                 rs.referencedentity AS [parent],
                 cte.path + '/' + rs.referencedentity AS [path],
                 cte.depth + 1 AS [depth]
          FROM   cte AS cte
                 INNER JOIN
                 metadata.relationship_n_1 AS rs
                 ON cte.parent = rs.referencingentity
          WHERE  cte.depth < 3)
SELECT   *
FROM     cte
ORDER BY depth;

1. All [child] columns have the same value. This is clearly wrong.
   • actual
   • expected
2. When I used (2) instead of (1), the result changed. This is also strange.
