Question

SQL CODE：

SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0;
SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0;
SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='TRADITIONAL,ALLOW_INVALID_DATES';

DROP TABLE IF EXISTS `db`.`zip_codes` ;

CREATE TABLE IF NOT EXISTS `db`.`zip_codes` (
  `zip` CHAR(5) NOT NULL COMMENT '',
  PRIMARY KEY (`zip`)  COMMENT '')
ENGINE = InnoDB;

DROP TABLE IF EXISTS `db`.`houses` ;

CREATE TABLE IF NOT EXISTS `db`.`houses` (
  `house_id` INT(11) NOT NULL AUTO_INCREMENT COMMENT '',
  `zip` CHAR(5) NOT NULL COMMENT '',
  `user_id` INT(11) NOT NULL COMMENT '',
  PRIMARY KEY (`house_id`)  COMMENT '',
  INDEX `fk_houses_users1_idx` (`user_id` ASC)  COMMENT '',
  INDEX `fk_houses_zip_codes1_idx` (`zip` ASC)  COMMENT '',
  CONSTRAINT `fk_houses_users1`
    FOREIGN KEY (`user_id`)
    REFERENCES `db`.`users` (`user_id`)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION,
  CONSTRAINT `fk_houses_zip_codes1`
    FOREIGN KEY (`zip`)
    REFERENCES `db`.`zip_codes` (`zip`)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION)
ENGINE = InnoDB
AUTO_INCREMENT = 24
DEFAULT CHARACTER SET = latin1;

SET SQL_MODE=@OLD_SQL_MODE;
SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS;
SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS;

我得到的错误：

Executing SQL script in server
ERROR: Error 1005: Can't create table 'db.zip_codes' (errno: 150)
SQL Code:
        CREATE TABLE IF NOT EXISTS `db`.`zip_codes` (
          `zip` CHAR(5) NOT NULL COMMENT '',
          PRIMARY KEY (`zip`)  COMMENT '')
        ENGINE = InnoDB

SQL script execution finished: statements: 4 succeeded, 1 failed

在其中一行中，我注意到它表示INDEX fk_houses_zip_codes1_idx（zip ASC）评论＆＃39;＆＃39;，我取出了ASC部分，它仍然产生了同样的错误。我知道当外键引用不正确或属性类型不相同时会出现1500错误。我仔细检查了所有这些原因，似乎没有错。有谁知道我做错了什么？

编辑：用户表

DROP TABLE IF EXISTS `db`.`users` ;

CREATE TABLE IF NOT EXISTS `db`.`users` (
  `user_id` INT(11) NOT NULL AUTO_INCREMENT COMMENT '',
ENGINE = InnoDB
AUTO_INCREMENT = 23
DEFAULT CHARACTER SET = latin1;
