Question

我在MacOSX上使用MySQL Workbench 5.2.45我使用EER Diagram功能设计了一个数据库，然后尝试了正向工程来生成我的数据库以放在我的本地服务器上。我收到错误代码：错误1005：无法创建表（错误号：150）

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';

CREATE SCHEMA IF NOT EXISTS `Finance` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci ;
USE `Finance` ;

-- -----------------------------------------------------
-- Table `Finance`.`DatabaseUser`

CREATE  TABLE IF NOT EXISTS `Finance`.`DatabaseUser` (

    ON UPDATE NO ACTION,
  CONSTRAINT `InstrumentGrant`
    FOREIGN KEY (`DonorID` , `RecipientID` )
    REFERENCES `Finance`.`Entities` (`ID` , `ID` )
    ON DELETE NO ACTION
    ON UPDATE NO ACTION)
ENGINE = InnoDB;

USE `Finance` ;


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

我一直在尝试帖子（Error Code: 1005. Can't create table '...' (errno: 150)）中建议的解决方案，但这似乎不是问题。 1.数据类型相同我正在引用主键 3.外键名称是唯一的 4.表格都是InnoDB 5.不涉及SET NULL 等

你能帮忙吗？

Answer 1

更改Grant表中的外键约束。

参考http://www.sqlfiddle.com/#!2/04945

  CONSTRAINT `InstrumentGrant`
    FOREIGN KEY (`RecipientID`)
    REFERENCES `Entities` (`ID`)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION,
  CONSTRAINT `InstrumentGrant_2`
    FOREIGN KEY (`DonorID`)
    REFERENCES `Entities` (`ID`)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION

根据需要命名约束。

解决：

在导出菜单中，选择“生成单独的CREATE INDEX语句”选项以避免此错误。
