Description

Retrieves BLOB field values from the provider.

Call FetchBlobs to retrieve BLOB field values from a provider when this information is not provided automatically. BLOB field values are automatically included in data packets unless the provider includes poFetchBlobsOnDemand in its Options property. (If the client dataset uses an internal provider, that provider's Options property is available as the client dataset's Options property.)

There is no need to call FetchBlobs if the provider automatically includes BLOB data or if the client dataset's FetchOnDemand property is True.
