How to map table names and column name different from model in onmodelcreating method in Entity Framework -6?

Question

I have my database with table names starting with \"tbl\" prefix and column names like \"ua_id\" which are understandable in context of project but problematic if used in a mode

Answer 1

If you are using Code First, you can simply decorate your model with Table and Column attribute and give it the database names.

[Table("tbl_Student")]
public class Student
{
    [Column("u_id")]
    public int ID { get; set; }
}

These attributes are available in the System.ComponentModel.DataAnnotations.Schema namespace

Answer 2

You can keep following inside OnModelCreating

modelBuilder.Entity<MyModel>()
.Property(e => e.MyColumn).HasColumnName("DBColumn")

Answer 3

And if you're not using code-first, just select a table in the model diagram, hit F4 (properties) and change the name.
