Reproduced in 5.1.43. Could not reproduce it in 5.0.66
-----Original Message----- From: Yang Zhang [mailto:yanghates...@gmail.com] Sent: Wednesday, February 17, 2010 6:05 PM To: mysql@lists.mysql.com Subject: auto_increment weirdness Hi, for some reason, I have an auto_increment field that's magically bumped up to the next biggest power of 2 after a big INSERT...SELECT that inserts a bunch of tuples (into an empty table). Is this expected behavior? I couldn't find any mention of this from the docs (using the MySQL 5.4.3 beta). Small reproducible test case: First, generate some data: from bash, run "seq 30000 > /tmp/seq" Next, run this in mysql: create table x (a int auto_increment primary key, b int); create table y (b int); load data infile '/tmp/seq' into table y; insert into x (b) select b from y; show create table x; This will show auto_increment = 32768 instead of 30000. Is this a bug introduced in the beta? Has it been fixed in newer releases? Couldn't find a mention in the bug database.
