Hope it is fixed in 5.6.25 but do you think in 5.6.24 it was a feature or miss in backward compatibility during the build phase?
Description: Renaming an empty table with a value in autoinc id to another table name resets the autoinc to 0? (edited) It happens in Mysql 5.6.24-72.2-log and not in 5.6.23-72.1-log Fyi. Its Percona-Mysql server. Not sure if this is in Mysql. How to repeat: mysql> show create table audit_CHECKER \G *************************** 1. row *************************** Table: audit_CHECKER Create Table: CREATE TABLE `audit_CHECKER` ( `id` bigint(11) unsigned NOT NULL AUTO_INCREMENT, `created_at` datetime DEFAULT NULL, PRIMARY KEY (`id`), KEY `index_audits_on_created_at` (`created_at`) ) ENGINE=InnoDB AUTO_INCREMENT=111111111 DEFAULT CHARSET=latin1 1 row in set (0.00 sec) mysql> select * from audit_CHECKER ; Empty set (0.00 sec) mysql> rename table audit_CHECKER to audit_CHECKER_DAMN; Query OK, 0 rows affected (0.01 sec) mysql> show create table audit_CHECKER_DAMN; +--------------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Table | Create Table | +--------------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | audit_CHECKER_DAMN | CREATE TABLE `audit_CHECKER_DAMN` ( `id` bigint(11) unsigned NOT NULL AUTO_INCREMENT, `created_at` datetime DEFAULT NULL, PRIMARY KEY (`id`), KEY `index_audits_on_created_at` (`created_at`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 | +--------------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ 1 row in set (0.00 sec) mysql> select version(); +-----------------+ | version() | +-----------------+ | 5.6.24-72.2-log | +-----------------+ 1 row in set (0.00 sec) mysql> Suggested fix: The renamed table should not reset the auto-inc id, it should carry forward as however it is in source table.
