I have a table which has a hierarchy structure ,like this
Child Parent
1 0
2 0
3 2
4 2
5 3
6 3
7 3
8 4
9 5
10 1
Another table which has a link to the hierarchy table
Product Child
Sweet 8
Boot 8
Sock 7
Car 10
So it looks something like this
1-
10-
Car
2-
3-
5-
9
6
7-
Sock
4-
8-
Sweet
Boot
Quite simple.
Now the problem, as you can see the tree from 1-10 has a car, 2-3-7 has Sock and 2-4-8 has Sweet and Boot.
But 2-3-5-9 and 2-3-6 have no products.
What I need to be able to do is remove the items so that every tree has a product. What you should be left with is:
1-
10-
Car
2-
3-
7-
Sock
4-
8-
Sweet
Boot
So removing 5, 6 and 9 from the structure, but still keeping 2 and 3.
This is driving me mad and got me going in circles.
