I can't think of other way of doing it. ;)
Code:
select oren into #oren from table1
select apple into #apple from table1

select * from #oren, #apple where #oren.oren = #apple.apple
drop table #oren
drop table #apple
Hope that helps.
Cheers

How about a self join of the fruits table:

SELECT F1.oren, F2.apple
FROM Fruits F1
INNER JOIN Fruits F2 ON F1.oren = F2.apple

But why would you have a table structured this way? I'm having trouble understanding the relationship between the two columns you are trying to express.
