The problem is that your way, there is no indicated way to determine
which node is which. For instance is you update any of your nodes
then the node list would be out of order and your list would not
work.

expert SQL developer and was wondering if there are known ways to traverse
the linked lists. Any information that can point me in the direction to
figure this out would be appreciated. The table contains many linked lists
