hierarchical relationship, how to query
HI,
I've got the following data in my table:
P_KEY = 1 REL_KEY = NULL
P_KEY = 2 REL_KEY = 1
P_KEY = 3 REL_KEY = 2
I only know P_KEY = 3.
How should I write my query to obtain the highest level of the hierarchy, P_KEY = 1? Here are 3 levels, but levels can be more or less.
Thankx, Ronald.
