Mysql：没有键名，但是无法创建表（errno：121）

Question

Yes, I have read all tpoics about error 121 but I still get

Can't create table 'catalog_category_flat_store_1' (errno: 121)

My query does not contain any CONSTRAINTs or key names

DROP TABLE IF EXISTS `catalog_category_flat_store_1`;
CREATE TABLE `catalog_category_flat_store_1` (
  `entity_id` int(10) NOT NULL,
  PRIMARY KEY (`entity_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Renaming table does help but is not an option here (Don't like to rewrite Magento)

For SHOW ENGINE INNODB STATUS I don't have the PROCESS privilege.

What is wrong with this query?

Answer 1

The query is valid, so can could be conflicting with another table's constraint name. Try specifying the PK name via CONSTRAINT pk_id PRIMARY KEY ( entity_id )

DROP TABLE IF EXISTS `catalog_category_flat_store_1`;
CREATE TABLE `catalog_category_flat_store_1` (
  `entity_id` int(10) NOT NULL,
  CONSTRAINT `pk_id` PRIMARY KEY (`entity_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Answer 2

它对我有用，请尝试以管理员权限运行mysql并检查用户数据库是否具有所有权限，例如drop，create等。

Looks like my innoDB is broken. I found my problem and a solution. Not done testing but looks promissing:
