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 model i.e names should be readable or meaningful(not like indicative names defined in database).
So I want to map them in my onmodelcreating method but I have no idea about it. I studied it in following blog:
http://weblogs.asp.net/scottgu/entity-framework-4-code-first-custom-database-schema-mapping
but this is for EF 4.1 and method doesn't work for EF 6.(mapsingletype method)
I want to map my tables by columns to my model as I can't change the column names. I just want the newer version of that syntax in the blog.
Thank You.
Map Entity to Table. Code-First will create the database tables with the name of DbSet properties in the context class, Students and Standards in this case. You can override this convention and give a different table name than the DbSet properties, as shown below.
A DbContext instance represents a session with the database and can be used to query and save instances of your entities. DbContext is a combination of the Unit Of Work and Repository patterns. Entity Framework Core does not support multiple parallel operations being run on the same DbContext instance.
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
You can keep following inside OnModelCreating
modelBuilder.Entity<MyModel>()
.Property(e => e.MyColumn).HasColumnName("DBColumn")
And if you're not using code-first, just select a table in the model diagram, hit F4 (properties) and change the name.
