I have a table with these columns:
id, node, parent_node_id
The top-most nodes would have a parent_node_id of
NULL. Is it possible to get a node, and all its parent
nodes, in a single query?
For example, a node might be:
books > computers > databases > oss > postgres
and the rows fetched would be:
1,books,NULL
2,computers,1
3,databases,2
4,oss,3
5,postgres,4
TIA,
CSN
