MySQL错误1005

Question

在服务器

中执行SQL脚本

ERROR: Error 1005: Can't create table '.\numbers\like.frm' (errno: 121)
SQL Code:
        -- -----------------------------------------------------
        -- Table `numbers`.`like`
        -- -----------------------------------------------------
        CREATE TABLE IF NOT EXISTS `numbers`.`like` (
          `like_id` INT NULL AUTO_INCREMENT,
          `like_date` DATE NULL,
          `like_number` INT NULL,
          `like_page` VARCHAR(45) NULL,
          `like_user_name` VARCHAR(45) NULL,
          `user_id` INT NULL,
          PRIMARY KEY (`like_id`),
          INDEX `user_id_idx` (`user_id` ASC),
          CONSTRAINT `user_id`
            FOREIGN KEY (`user_id`)
            REFERENCES `numbers`.`user` (`user_id`)
            ON DELETE CASCADE
            ON UPDATE CASCADE)
        ENGINE = InnoDB

 SQL script execution finished: statements: 9 succeeded, 1 failed

 Fetching back view definitions in final form.
 Nothing to fetch

谁能告诉我这是什么问题？
