Two handler objects were present, one was used for an insert and the other for a select The state of the statistics was local to the handler object and thus the other handler object didn't notice the insert. Fix included: 1) Add a new variable key_stat_version added to whenever statistics was considered in need of update (previously key_stats_ok= FALSE in those places) 2) Add a new handler variable key_stat_version assigned whenever key_stats_ok= TRUE was set previously 3) Fix records_in_range to return records if records <= 1 4) Fix records_in_range to add 2 to rec_per_key to ensure we don't specify 0 or 1 when it isn't and thus invoking incorrect optimisations. 5) Fix unique key handling for HEAP table in records_in_range
