我在mysql工作台中创建第一个表时遇到了一个小问题。当我创建两个表并查看正向工程进度时，我得到如下消息：
在服务器中执行sql脚本错误：错误1064:您的sql语法有错误；检查与您的mariadb服务器版本相对应的手册，了解使用“index”附近的正确语法 fk_person_has_user_person_idx ( person_ID asc）可见，第8行的“约束”
sql代码：

-- -----------------------------------------------------
        -- Table `customers`.`person_has_user`
        -- -----------------------------------------------------
        CREATE TABLE IF NOT EXISTS `customers`.`person_has_user` (
          `person_ID` INT NOT NULL,
          `user_person_ID` INT NOT NULL,
          PRIMARY KEY (`person_ID`, `user_person_ID`),
          INDEX `fk_person_has_user_user1_idx` (`user_person_ID` ASC) VISIBLE,
          INDEX `fk_person_has_user_person_idx` (`person_ID` ASC) VISIBLE,
          CONSTRAINT `fk_person_has_user_person`
            FOREIGN KEY (`person_ID`)
            REFERENCES `customers`.`person` (`ID`)
            ON DELETE NO ACTION
            ON UPDATE NO ACTION,
          CONSTRAINT `fk_person_has_user_user1`
            FOREIGN KEY (`user_person_ID`)
            REFERENCES `customers`.`user` (`person_ID`)
            ON DELETE NO ACTION
            ON UPDATE NO ACTION)
        ENGINE = InnoDB
SQL script execution finished: statements: 7 succeeded, 1 failed
Fetching back view definitions in final form.
Nothing to fetch

有人能解释一下吗？
