EFExtension

Extension for entity framework in .NET Framework. Helping developers are easy to use EF6.0 to call store procedure, view, function in SQL Server

• Nuget:

  https://www.nuget.org/packages/EFExtension/

• Note : You can download sample app in this source or this link: https://github.com/vosonha89/EFExtension/blob/master/dist/package_0.0.1/sample/EFExtension.Console.zip

Usage

1. How to call Store Procedure

• Your store procedure returns only one data:

  Context.ExecuteStoreProcedureOneDataResult

• Your store procedure returns result set data:

  Context.ExecuteStoreProcedureOneResultSet

  • Example:

  order.OrderItems = ctx.ExecuteStoreProcedureOneResultSet<OrderItem>("dbo.sp_GetOrderDetail",
                        new SimpleSqlParam { Name = "@OrderId", Value = order.Id },
                        new SimpleSqlParam { Name = "@CustomerId", Value = 1 }
                        );

  • Or

  order.OrderItems = ctx.ExecuteStoreProcedureOneResultSet<OrderItem>("dbo.sp_GetOrderDetail",
                        new SqlParameter { ParameterName = "@OrderId", Value = order.Id, Direction = System.Data.ParameterDirection.Input },
                        new SqlParameter { ParameterName = "@CustomerId", Value = 1, Direction = System.Data.ParameterDirection.Input }
                        );

• Your store procedure returns multiple result set data:

  Contex.ExecuteStoreProcedureMultipleResultSet

  • Example:

   List<object> result2 = ctx.ExecuteStoreProcedureMultipleResultSet("dbo.sp_GetOrderDetail",
                          new SimpleSqlParam { Name = "@OrderId", Value = order.Id },
                          new SimpleSqlParam { Name = "@CustomerId", Value = 1 })
                          .With<OrderItem>()
                          .With<Customer>()
                          .Execute();

  • Or

   List<object> result3 = ctx.ExecuteStoreProcedureMultipleResultSet("dbo.sp_GetOrderDetail",
                        new SqlParameter { ParameterName = "@OrderId", Value = order.Id },
                        new SqlParameter { ParameterName = "@CustomerId", Value = 1 })
                        .With<OrderItem>()
                        .With<Customer>()
                        .Execute();

2. How to call Function

• Scalar:

  Context.ExecuteScalarFunction

  • Example:

  var scalarResult = ctx.ExecuteScalarFunction<DateTime>("dbo.ScalarValueFunc", DateTime.Now);

• Table:

  Context.ExecuteTableFunction

  • Example:

  var tableResult = ctx.ExecuteTableFunction<Product>("dbo.TableValueFunc", "Sir Rodney's Scones");

3. How to use View

Creating View in your database -> Creating object mapping using attribute [Table(Viewname)] -> Adding like a DbSet to your context -> Using like a entity

• Example:
  • Creating object mapping using attribute [Table(Viewname)]

  [Table("V_ProductWithSupplier")]
  public class ProductWithSupplierView
  {
      public int Id { get; set; }
      public string ProductName { get; set; }
      public int SupplierId { get; set; }
      public decimal UnitPrice { get; set; }
      public string Package { get; set; }
      public bool IsDiscontinued { get; set; }
      public string CompanyName { get; set; }
      public string ContactName { get; set; }
      public string ContactTitle { get; set; }
      public string City { get; set; }
      public string Country { get; set; }
      public string Phone { get; set; }
      public string Fax { get; set; }
  }

  • Adding like a DbSet to your context

   // Views
   public DbSet<ProductWithSupplierView> ProductWithSupplierView { get; set; }

  • Using like a entity

  List<ProductWithSupplierView> data = ctx.ProductWithSupplierView.ToList();
