SQL Query - Where cause where only exists once...?

Question

I have a query/result set that I'm trying to query/filter.
What I need is, in two of the 5 columns in the resultset, I need returned where the record only exists once. In the other 3, they have to meet certain criteria.
So, logically it would true for all: give me results where results in column 1,2 only exist once AND column3 is null and column3 is null and column5 =Server
Not sure if this make sense....? :/

I can give a example table....how do I ''code'' the script?An example certainly would help (also please mention your database version).
Put your example between the tag (put the tag before and after your example).
Use CTAS or CREATE TABLE + INSERT statements, and the desired output you want from that.
See the FAQ for more information regarding tags:

CTAS =  Create Table As Select ....<your query>.
It is less work than providing CREATE TABLE and INSERT INTO statements.
If your database version allows for it, you can achieve the same using the WITH clause.
But in the end: providing working and (small but complete) examples will boost the response to your question.
Also, chances are that when you put up an example, you'll see the answer yourself.

Never mind, bedtime for me ;)
