Execute stored procedures with Entity Framework Core

DbContext extension with LoadStoredProc method which creates an IStoredProcBuilder.

The method handles :

  • Extra column in result set
  • Extra property in model
  • Null values in result set
  • Underscores or hypens in result set column names ("column_name" is mapped to ColumnName property)
  • Int (db) to enumeration (result model) mapping

Example

List<Model> rows = null;

ctx.LoadStoredProc("dbo.ListAll")
   .AddParam<T>("limit", 300L)
   .AddParam<T>("limitOut", out IOutParam<long> limitOut)
   .Exec(r => rows = r.ToList<Model>());

long limitOutValue = limitOut.Value;

ctx.LoadStoredProc("dbo.ReturnBoolean")
   .AddParam<T>("boolean_to_return", true)
   .ReturnValue(out IOutParam<bool> retParam)
   .ExecNonQuery();

bool b = retParam.Value;

ctx.LoadStoredProc("dbo.ListAll")
   .AddParam<T>("limit", 1L)
   .ExecScalar(out long l);
