Hi List,
I am a noob trying to do something that seems like it should be easy but I can't figure it out.
I have a table like so:
id | ref_id | sts
------------------
1 | | 0
2 | 1 | 1
3 | | 0
4 | | 0
5 | 4 | 1
6 | | 0
7 | 6 | 1
I want to find the max(id) whose sts is 0 but whose id is not referenced by ref_id.
so the answer would be id=3.
Thanks for any pointers,
Steve
