列的Npgsql错误

Question

我有一个模型，并且有相同的数据库表。 两者都是同步的。 我在其他服务器上有另一个数据库，我为此使用相同的模型，但使用不同的dbContext。

我的系统执行的操作是在本地dbcontext中检查并获取一些行，然后检查具有唯一ID的同一行。 但是当它在表中添加行时，给了我以下错误

ERROR: 42703: column "etrue" does not exist

我不知道怎么了我的表与模型中声明的列相同

这是我的模特

我不知道为什么将E放在列值中

Answer 1

这看起来像是在提交864c4e9中引入的 Npgsql中的错误，并在2013年7月5日在提交b07ae85中得到了修复 。

看起来版本2.0.14.3及更高版本包含此修复程序。 更新NuGet软件包将获取更新，或者您可以从其发布页面获取二进制文件。
