Question

ADO.NET EF does not support things like Math.Pow and Math.Log so I was wondering how I can get around this. I need to be able to use an ORDER BY on a calculated value using ADO.NET EF.

You can using Entity SQL, but I wouldn’t recommend it

using System.Data.EntityClient;  EntityConnection conn = new EntityConnection(myContext.Connection.ConnectionString); conn.Open(); EntityCommand cmd = conn.CreateCommand(); cmd.CommandText = @'Select SqlServer.Power(t.MyValue, 2) From MyEntities.MyTable As t'; var result = cmd.ExecuteReader(System.Data.CommandBehavior.SequentialAccess); result.Read(); var valuePower2 = result.GetValue(0); conn.Close(); 

To do dynamic order by’s and where clauses use Dynamic Linq
