Thanks, what about if mysqld restart, does auto_increment gets reset ?
I saw this happened to Innodb, if table is empty and server restart, auto_incremnet gets
reset to 0

is there a auto_increment counter for MyISAM to assign a new value to auto_increment
columns?
Yes

It is stored with the table definition. It is only reset to 0 when the table is
(re)created. You can get the last AutoInc for the record that was just added by "Select
Last_Insert_Id()". See http://dev.mysql.com/doc/refman/5.0/en/example-auto-increment.html
