Dynamic Outputparameters do not work with QUERY.

Hi guys,

Following the provided test case:

public void TestSupportForDynamicParametersOutputExpressions()
        {
            var bob = new Person { Name = "bob", PersonId = 1, Address = new Address { PersonId = 2 } };

            var p = new DynamicParameters(bob);
            p.Output(bob, b => b.PersonId);
            p.Output(bob, b => b.Occupation);
            p.Output(bob, b => b.NumberOfLegs);
            p.Output(bob, b => b.Address.Name);
            p.Output(bob, b => b.Address.PersonId);

            connection.Execute(@"
SET @Occupation = 'grillmaster' 
SET @PersonId = @PersonId + 1 
SET @NumberOfLegs = @NumberOfLegs - 1
SET @AddressName = 'bobs burgers'
SET @AddressPersonId = @PersonId", p);

            bob.Occupation.IsEqualTo("grillmaster");
            bob.PersonId.IsEqualTo(2);
            bob.NumberOfLegs.IsEqualTo(1);
            bob.Address.Name.IsEqualTo("bobs burgers");
            bob.Address.PersonId.IsEqualTo(2);
        }

If connection.Query is used instead of .Execute, it will not work, although p will changed SqlValues accordingly, at the end it will not update bob's value. If thats as expected, please ignore.

Start with the provided TestSupportForDynamicParametersOutputExpressions case and compare connection.Execute with connection.Query while inspecting DynamicParameters.Output behavior. Verify whether Query propagates the resulting SqlValues back to bob; done means the Query variant matches the stated output assertions, or the expected behavior is clarified if it should not.
