Is it possible to create a tree structure ( as in 'C' )
using PL/SQL or a sorted array kind of thing for faster processing of repetative data ? If so How do we do it ?

Anand,

Yes it is possible to create a tree structure
using sql*plus/pl/sql , Try using the
a combination of
START WITH & CONNECT BY commands in sql.
Get back to me if you have problems.

Hi,

I have a followup question on this,

Is it besides following the tree with 'start with' and 'connect by' possible to save the previous levels in a view.

This because I want to handle the data in Crystal Reports, wich does not understand the above mentioned commands.

So what I would like to get is a view with the foriegn keys of all levels of the tree. Of course this would mean that the tree will no longer be endless extensible, but that does not mather to me because i have a predefined tree depth.

Hope someone knows a sollution for this,

Vincent de Haan
