Question

I have been trying the model-first method when designing my application. We usually like to add a prefix to our tables in larger databases so it is easier to find stuff. For example:

• sc_ = Shopping cart tables
• wb_ = Water billing tables
• ea_ = Employment Application tables

The class I have setup looks like this so far.

public class EFDbContext : DbContext
{
    public DbSet<Transaction> Transactions { get; set; }
    public DbSet<TransactionItem> TransactionItems { get; set; }
    public DbSet<Response> Response { get; set; }
}

Web.config (set currently for local database testing):

    <add name="EFDbContext" connectionString="Data Source=.\SQLEXPRESS;Integrated Security=SSPI;Initial Catalog=database" providerName="System.Data.SqlClient"/>

What do I need to change so that the Transaction object gets linked to the sc_Transactions table? I haven’t seen in my searching that clarifies this.

As a second question, do I have to manually create my tables?

You can override the OnModelCreating method from DbContext in your EFDbContext class:

public class EFDbContext : DbContext
{
    public DbSet<Transaction> Transactions { get; set; }
    public DbSet<TransactionItem> TransactionItems { get; set; }
    public DbSet<Response> Response { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Transaction>().MapSingleType().ToTable("someTableNameHere");
    }
}
