  • MrGeeC Gerard Chartier I know this is now an old post but it is still very relevant. I was particularly interested in the topic of hierarchical data. Very helpful but I believe one common requirement was not discussed - querying the whole set of data to return the full hierarchy. It seems to me that the Path Enumeration approach would be best for that because a simple query or one table ordered by the path would give the required result.
    I am also wondering, as it would be a small overhead, whether combining the Path Enumeration and Adjacent List approaches might provide the best solution, with each resolving the the omission in the other.
