Using Entity Framework 6 with Multiple DB Schemas but using One DBContext

dbcontext db-schema entity-framework


I have an application using EF as ORM. The database used to have one schema, dbo and everything was working fine. I recently organized my tables into 4 different schemas. Some tables of one schema have dependencies on tables that reside on a different schema. All seems to be valid on the SQL side.

On the app side all db interactions through EF are not working anymore. The code compiles, the schemas are visible in the solution, the model mappings point to the right schemas, but once I try to insert a row to a table it does not work.

I have seen a few posts about using multiple schemas will require using multiple DBContexts but I would rather use one DBContext. All my schemas have the same owner dbo and I do not see a reason of using multiple DBContexts.

Does anyone know if there is a way to achieve this?

Accepted Answer

You can map each table to its own schema by fluent mapping only. In your DbContext subtype you should override OnModelCreating (if you haven't done so already) and add statements like this:

    .ToTable("t_Department", "school");

Entities that you don't map like this explicitly will be placed in the default dbo schema, or you can provide your own default by

In addition to the responce of Gert Arnold, you can also use Table attribute in your entity:

using System.ComponentModel.DataAnnotations.Schema;

[Table("t_Department", Schema = "school")]
public class Department
    public int Id { get; set; }

    public string Name { get; set; }
