{
return a.Except (b).Union (b.Except (a));
}

How can I get the set difference of two result sets?
Say I have a result set (just one column in each):
result1:
'a'
'b'
'c'
result2:
'b'
'c'
I want to minus what is in result1 by result2: result1 - result2 such that it equals:
difference of result1 - result2:
'a'
