[mapguide-users] King.Oracle return allways all columns

[Haris Kurtagic]

Hi Bruno,

That is correct King.oracle Provider is executing select for all columns
in FDO class definition, regardless if you set property collection for
select command.

I suppose I could change this. 
I wouldn't like to add a lot of overhead in checking if filter
conditions matches property collection, order etc..
So for example when setting property collection and order properties,
the provider will return with error if some property is in order not in
select collection.

I'm trying to select a single column using the King.Oracle FDO provider
But it allways return all columns

This is a sample code of what i'm trying to do

  FdoPtr<FdoISelect>        sampleSelect;
  FdoPtr<FdoIFeatureReader> sampleFeatureReader;
  FdoPtr<FdoIdentifier> queryPropertyName;

  sampleSelect = (FdoISelect
*)m_connection->CreateCommand(FdoCommandType_Select);
  sampleSelect->SetFeatureClassName("MyFeatureClassName");

  FdoPtr<FdoIdentifierCollection> propertyCollection = 
sampleSelect->GetPropertyNames();
  queryPropertyName = FdoIdentifier::Create("MyColumnName");
  propertyCollection->Add(queryPropertyName);
  sampleFeatureReader = sampleSelect->Execute();

When i drill down the featureReader it return all columns with all
values...
This same code works fine with other provider like the SDF..
