C++
virtual System::OleVariant __fastcall InternalRowRequest(const System::OleVariant &Row, Datasnap::Dbclient::TFetchOptions Options);
Description
Provides the underlying implementation of the RowRequest method.
The RowRequest method calls InternalRowRequest to assemble the specified information after generating a BeforeRowRequest event and before generating an AfterRowRequest event. InternalRowRequest passes this request on to its associated Resolver.
The Row parameter is an OleVariant that describes the record about which information is requested.
InternalRowRequest returns the requested information in a delta packet.
