Hi,

On 8.1.7.2 (soon to be .3) on HP/UX 11.0, a developer needs to get the top parent associated with a lower level row. Expanding on Oracle's EMP example:

EMP             MGR             LEVEL
King                            1
Greenberg       King            2
Faviet          Greenberg       3
Chen            Greenberg       3
Sciarra                 1
Urman           Sciarra 2
Popp            Urman           3
Jesse           Urman           3

...I need to know that the top-level manager for "Jesse" is "Sciarra". In
our live data, however, we currently have 9 levels (engineering bill-of-materials) and there is no set maximum for levels.

Anyone have an idea how to return:
Jesse Urman Sciarra 3

...for this? The START WITH...CONNECT BY can only give the PRIOR manager
and not the top level.

TIA!
