Reproducible with MyISAM, Aria, InnoDB, MEMORY.
Not reproducible with use_stat_tables = NEVER.
Test case:
set use_stat_tables = complementary;
|
|
drop table if exists t1;
|
|
create table t1 (i int) engine=InnoDB;
|
lock table t1 write;
|
analyze table t1;
|
alter table t1 add column a varchar(8);
|
|
# Cleanup
|
drop table t1;
