实体框架PK名称

Question

I work with entity framework 6.0 with code first.

I need to connect to database table created by Microsoft Access ODBC.

When I try to connect to a table, a receive an error about the PK name.

Entity Framework create a PK with name PK_dbo_TABLENAME that create problem with Microsoft Access. If I rename it, there are no problem.

How I can force different name to entity framework key?

I search in data-annotation syntax but with no result.

Thanks.

Answer 1

If you are saying that your column name is not the same name as the property you're using (ie TableID vs Id ) you can use the [Column()] attribute to override the name:

[Column("GeoLocationDetailId")]
 public Guid Id { get; set; }

If you're referring to the schema not recognize your Primary Key, you can add the [Key] attribute on that property and it will pick it up :

    [Key, DatabaseGenerated(DatabaseGeneratedOption.None)]
    public Guid Id { get; set; }

If you're using Model configuration, you can use the HasKey method in the same manner you would with the [Key] attribute:

        modelBuilder.Entity<GeoLocationEntity>()
            .HasKey(e => e.Id)

最后，我从Sql Management Studio中手动重命名PK。
