WebOct 2, 2015 · I was trying to reverse the query from bottom to top instead of top to bottom using the recursive with clause. Same results except top row would be 'ADAMS' and last row would be 'King'. Of course it is pretty easy to take the result and reverse it, but that would not be using the recursive with clause to walk the tree in reverse.
