Description
MySQL bug http://bugs.mysql.com/bug.php?id=57657 was fixed in 5.6.5, but the fix apparently was not merged to 10.0. It should be, eventually.
Test case from the bug report:
create temporary table t1_temp(i int); |
create temporary table tm_temp_temp (i int) engine=merge union=(t1_temp) insert_method=last; |
alter table tm_temp_temp insert_method=first; |
check table tm_temp_temp; |
