Question

I have a table with a column rank which contains
rank
1
2
3
4
5
6
7
8

When I delete number 5 I want the numbers above 5 to go down 1 number. So 6=5 7=6 8=7

$start_rank = singleSelectQuery('SELECT rank FROM menu WHERE menuID='.$menuID.'');
$update_rank = Query("UPDATE menu SET rank='rank - 1' WHERE partnerID=". $partnerID ." AND rank>".$start_rank['rank']);

This code does not update the numbers and i do not have a clue what I’m doing wrong:)
Oh, I don’t get any errors…
What did I do wrong?

EDIT
when i echo update_rank i get:
UPDATE menu SET rank='rank - 1' WHERE partnerID=1 AND rank>5)

Answer 1

Your syntax is wrong : rank='rank - 1'

should be

rank=rank - 1.

Also the leading .")" shouldn’t be there at all.
