Hi,
I have a table called tab1(parent number,child number).

sample data
------------
parent child
1 2
1 3
2 4
2 5
4 6
4 7
3 8
3 9

Now i want to find out all the childs and their childs and their childs.

Suppose i want all the childs of parent 1 and then insert the data into a temporary table.

I will be passing a array of parent ids and it should search for all childs and their childs and fill the temporary table.

How can i do this either through sql or plsql.

i should get the data like

child
------
2
3
4
5
6
7
