I'm revisiting my initial code and I realize I don't quite understand
the business rules.
It could be as simple as "return the row for each ID that contains the
lowest value for N1, and the row that contains the lowest value for
N2". But that wouldn't require you to say "if n2 is not 0, I ignore the
value of n1".
In the case below, why is the row [c1, 4, 0] included? Because it
contains 4 in n1, or because it contains 0 in n2?
Why don't you include [c1, 4, 5]? I don't understand the phrase "should
return 2 lines containing 4". There are 3 lines containing 4.
How about adding a few more lines to the test case and explaining the
result.
If you add [c1, 2, 0] what are the results?
If you add [c1, 2, 5] what are the results?

Hi all,
I need to scan this table and get the lines having the lowest value for n1 or n2
id n1 n2
c1 4 0
c1 3 4
c1 4 5
c1 5 6
If n2 is not 0, I ignore the value of n1.
So in this example I should return 2 lines containing 4 :
c1 4 0
c1 3 4
Thanks
