create table topology(
nid number(19) primary key,
parentid number(19) references topology(nid));
There is a self reference in the table.
I have Stored Data in a topological tree structure.
There is a single record at Top Level for which the parent id is null . Call it as owner.
This Owner has 2 children (Thats the parent id of this is nid of owner) Now these 2 children have 3 to 4 children each and further those children can have further.
The level of tree structure can be much bigger and its dynamic. There can be records adding in between tree strucure.
My Problem is I want a query or function which will return the sequential tree structure of an
element which I input. If I input a owner's id then it should retrieve all the hierarchy of children below that element and to whatever level it goes.
