Client datasets call SAS_SAS_RowRequest automatically to implement their FetchBlobs, FetchDetails , or RefreshRecord method. 

ProviderName indicates the provider associated with the dataset from which information should be fetched. 

Row is an OleVariant that describes the current record on the client dataset. 

RequestType indicates the type of information required. It is an integer version of the TFetchOptions type. (An integer because the value may be marshaled to a remote application server). To create a value for RequestType, take the corresponding TFetchOptions value, cast it to a Byte, and cast the result to an Integer:

Integer(Byte([foBlobs, foDetails]));

(int) (Byte) (TFetchOptions() << foBlobs << foDetails);

OwnerData contains custom information that is supplied by a client dataset's BeforeSAS_RowRequest event handler. This information is passed to the provider's BeforeSAS_RowRequest event handler. OwnerData returns custom information supplied by the provider's AfterSAS_RowRequest event handler. 

The requested data is returned as a delta packet.
