well my example was incomplete :
at the begin :
chapter_id | evolution | index
1 | 0 | 1
2 | 0 | 2
3 | 0 | 3
4 | 1 | 2
5 | 1 | 4
by using the sort function i obtain this :
chapter_id | evolution | index
1 | 0 | 1
4 | 1 | 2
2 | 0 | 2
5 | 1 | 4
3 | 0 | 3
that why i can't use ORDER BY...

in what way is this different than
... ORDER BY index ASC, evolution DESC;
?
