Entity Framework 7中表和属性的大小写不敏感名称 [英] Case insensitive name of tables and properties in Entity Framework 7

问题描述

我将Entity Framework 7与Npgsql适配器一起使用。 EF生成的SQL似乎是

I use Entity Framework 7 with Npgsql adapter. Sql generated by EF seems like

SELECT "r"."Id", "r"."Name" FROM "public"."Role" AS "r"

，并且在Postgres中不起作用，因为区分大小写政策。要使其正常工作，我需要编写创建表脚本

and it doesn't work in Postgres, because case-sensitive policy. To make it work i need to write create table script

CREATE TABLE "Role" (
    "Id" int,
    "Name" varchar(200)
);

但这很丑。有没有办法使EF生成不带引号或具有小写命名风格的脚本？

But it's ugly. Is there the way to make EF generate scripts without quotes or with lowercase naming style?

推荐答案

Npgsql生成引号有一个很好的理由到处都是-因此您绝对不应删除它们（即使在技术上也可以按照@natemcmaster所说）。不带引号的标识符由PostgreSQL自动转换为小写。实体框架需要能够将C＃属性映射到数据库列，但是C＃属性区分大小写。因此，如果您删除数据库的区分大小写功能，那您就开枪了...

There's a very good reason Npgsql generates quotes everywhere - so you definitely should not remove them (even if it's technically possible as @natemcmaster says). Identifiers without quotes are automatically converted to lowercase by PostgreSQL. Entity Framework needs to be able to map C# properties to database columns, but C# properties are case-sensitive; so if you remove database case sensitivity you're shooting yourself in the foot...

除非您有真正的问题（除了感知到的丑陋之外），否则您应该离开照原样。

Unless you have a real problem (aside from the perceived ugliness) you should leave things as they are.
