About Devart<\p>

Recently I wrote an interesting piece of sql using a cartesian product. The goal was to insert an item into the top-most position in a list given that some of the item positions are fixed. The table "list" is as follows:

|item|rank|fixed| | a | 1 | 1 | | b | 2 | 0 | | c | 3 | 0 | | d | 4 | 0 |

The idea is to insert the new item in the 0th position, and move every non-fixed item down. We can get part of the way there with a cartesian product of list and itself, filtering by rank and grouping by item:

select a.rank as oldrank, min(b.rank) as newrank from list a, list b where a.rank < b.rank group by a.item;

This gives the mapping oldrank/newrank, however we are missing a mapping for the last item in the list. This is fixed by extend "list b" using a union:

select a.rank as oldrank, min(b.rank) as newrank from list a, ( select rank from list union select max(rank) + 1 from list ) b where a.rank < b.rank group by a.item;

Lastly, we can filter the lists by "fixed" which gives our update statement:

update list set rank = ( select newrank from ( select a.rank as oldrank, min(b.rank) as newrank from list a, ( select rank from list where fixed = 0 union select max(rank)+1 from list ) b where a.rank < b.rank and a.fixed = 0 group by a.item ) c where oldrank = rank ) where fixed = 0;
