Hi, Folks: I have questions regarding how MyISAM handles auto_increment clolumn? 1. is there a auto_increment counter for MyISAM to assign a new value to auto_increment columns?
Yes
2. if MyISAM has the counter, is the counter stored in memory or disk? Thnaks
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
