是否有任何有用的工具或技巧可以自动(或快速)为MySQL中的给定表创建历史表触发器？ I’ve come across this tool so far,但它暂时没有更新.如果它是相关的,我使用MySQL Workbench的“模型”工具来构建我的数据库模型,然后将它们与我的本地数据库同步.

我想要的是能够为表提供创建脚本,并让工具神奇地吐出创建历史表和触发器的脚本,以插入到插入/更新/删除的历史表中.例如,如果我有具有复合PK a,b,外键c,d和属性e,f的表foo,它将为具有复合PK a,b,revisionNum和c,d的历史表foo_history生成创建脚本. ,e,f,从c和d中删除关系 – 可能还有一个列,表示操作的时间以及是否为INSERT / UPDATE / DELETE.

我很乐意制作这样一个脚本并分享它,如果它还不存在,但我不想重新发明*.如果没有,您认为其他人使用此类脚本最方便的格式是什么？您将如何将其纳入您的模型开发工作流程？

解决方法:

我为自己创建了这个小怪物php脚本,它从一些简写的txt文件生成SQL DDL,现在它可以生成历史表及其CREATE TRIGGER语句.

!DROP

person ZZZ
  ID

  N mother_id -> person
  N father_id -> person
  !FK mother_id, father_id -> family

family ZZZ
  P female_id -> person
  P male_id   -> person
