无法从MySQL Workbench转发设计此数据库

时间：2014-08-27 08:46:21

标签： mysql sql

使用MySQL Workbench我正在尝试转发架构，但我不断收到消息：

  

错误：错误1022：无法写入;表'tbl_banner_ad'中的重复键

我看过类似的问题，但所有的解决方案都说删除这个或删除它，但我不想删除那些会影响我的数据库工作方式的东西。

从我下面的SQL中，任何人都可以告诉我我需要做什么来摆脱这个错误，但不会摆脱任何参照完整性或类似的东西：

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';

编辑：我尝试删除tbl_banner_ads中的INDEX语句但我无法删除它，因为索引是外键的一部分。

答案 0 :(得分：3)

尝试并更改tbl_banner_ad的CREATE。改变这一部分：

   CONSTRAINT `payment_id`
    FOREIGN KEY (`payment_id`)
    REFERENCES `ibn_db`.`tbl_payments` (`_id`)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION,
  CONSTRAINT `user_id`
    FOREIGN KEY (`user_id`)
    REFERENCES `ibn_db`.`tbl_users` (`_id`)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION)

为：

  CONSTRAINT `payment_id1`
    FOREIGN KEY (`payment_id`)
    REFERENCES `ibn_db`.`tbl_payments` (`_id`)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION,
  CONSTRAINT `user_id1`
    FOREIGN KEY (`user_id`)
    REFERENCES `ibn_db`.`tbl_users` (`_id`)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION)

（或者，您可以命名约束以反映父表和子表名以及columnn-name。即tbl_payment_tbl_banner_ad_payment_id。
