index column There was actually two problems 1) when clustered pk, order by non pk index should also compare with pk as last resort to differ keys from each other 2) bug in the index search handling in ha_partition (was found when extending the test case Solution to 1 was to include the pk in key compare if clustered pk and search on other index. Solution for 2 was to remove the optimization from ordered scan to unordered scan if clustered pk.
