SQLServerSpatialProvider throws an exception when GetPropertyCount is called from an aggregate reader

[romicadascalescu]

SQLServerSpatialProvider thows an exception when GetPropertyCount is called from an aggregate reader.

The issue is in following files:
Providers\GenericRdbms\Src\SQLServerSpatial\Fdo\FdoRdbmsSqlServerOptimizedAggregateReader.h
Providers\GenericRdbms\Src\Fdo\FeatureCommands\FdoRdbmsFeatureReader.h

FdoRdbmsSqlServerOptimizedAggregateReader has following methods declared virtual public:

virtual FdoInt32 GetPropertyCount(); virtual FdoString* GetPropertyName(FdoInt32 index); virtual FdoDataType GetDataType(FdoString* idName); virtual FdoPropertyType GetPropertyType(FdoString* idName);

FdoRdbmsFeatureReader has following methods declared non-virtual private:

FdoInt32 GetPropertyCount(); This is an internal method to support the DataReader FdoString* GetPropertyName(FdoInt32 index); This is an internal method to support the DataReader FdoDataType GetDataType(FdoString* propertyName); This is an internal method to support the DataReader FdoPropertyType GetPropertyType(FdoString* propertyName);

Since FdoRdbmsSqlServerOptimizedAggregateReader is derivate from FdoRdbmsFeatureReader when we call a from a FdoRdbmsSqlServerOptimizedAggregateReader object one of those methods, we will calle methods from FdoRdbmsFeatureReader because methods are not virtual
