Vicențiu Ciorbaru	3dd08a11de	Fix another bug in dense_rank. ... When ordering by a column and partitioning by another, we must reset the peer_tracker for dense_rank, regardless if the value for the order column changes or not. Example: select a, b, dense_rank() over (partition by b order by a) a | b | dense_rank ---------------------- 1 | p1 | 1 2 | p1 | 2 2 | p2 | 1 // Here, without this fix we returned 0. 2 | p2 | 2 // And 1 here.	2016-04-13 10:39:06 +02:00
Vicențiu Ciorbaru	419c925069	Fix dense_rank returning minimum rank of 2 when using null columns. ... The bug was caused by a weird behaviour in test_if_group_changed, not returning true when testing for the first time after initializing the Cached_item list.	2016-04-11 10:46:58 +02:00
