如何使用PetaPoco或NPoco生成DDL？

[英]How to generate DDL using PetaPoco or NPoco?

原文 2014-02-11 22:04:37 5 2 c#/ poco/ petapoco/ npoco

I have just started using PetaPoco/NPoco in one of my projects and have to say that it rocks however, It seems that the library is not able to generate DDL and create a table based on the Poco. 我刚开始在我的一个项目中使用PetaPoco / NPoco并且不得不说它摇滚，但似乎该库无法生成DDL并创建基于Poco的表。 I know that OrmLite can do this. 我知道OrmLite可以做到这一点。

Is there a way/workaround that can be used to for example decorate the poco and then based on the attributes DBMS specific table scripts are generated? 是否有一种方法/解决方法可用于例如装饰poco，然后根据属性生成DBMS特定的表脚本？ eg Oracle, MSSql etc. 例如Oracle，MSSql等

Thank you 谢谢

No. PetaPoco seems (rightly) intent on staying small and lightweight, focusing on one thing (mapping between objects and IDb* concepts) and doing that well. 不，PetaPoco似乎（正确地）意图保持小巧轻便，专注于一件事（在物体和IDb *概念之间进行映射）并做得很好。

I could see this feature being semi-useful when running unit tests or very useful for prototyping, but IMO you want a DB migration manager to handle updates to your DB schema over time. 我可以看到这个功能在运行单元测试时非常有用，或者对于原型设计非常有用，但IMO希望数据库迁移管理器能够随着时间的推移处理数据库模式的更新。 Fluent Migrator is a good choice. 流利的Migrator是一个不错的选择。

For me, it's about a separation of where we are (current PetaPoco / NPoco classes) and how we got here (migrations). 对我而言，它是关于我们所处的位置（当前的PetaPoco / NPoco类）以及我们如何到达这里（迁移）。

Not sure exactly what you are after, but we use NPoco.T4 to generate our models from DB. 不确定你到底是什么，但我们使用NPoco.T4从DB生成我们的模型。 Maybe look into it. 也许看看吧。 You can find it on Nuget. 你可以在Nuget上找到它。
