Npgsql + Entity Framework + Edmx 与列类型位

Question

I have been using Npgsql with Entity Framework + .net, while using column type as bit in the ssdl part of edmx file, its throwing an error like "The type bit is not a primitive type" .

Can anyone tell me how to use bit type with edmx file.

Thanks.

Answer 1

Did you use bit for boolean types? If so, you need to change your bit type to bool in your database.

If not, you need to use smallint in Entity Model.

Answer 2

可能是数据库不支持您要存储的某种数据类型。
