Tak w nawiasie z dokumentacji (dotyczy GetData, SetData idt.):

If the data is NULL, GetData returns false and no data is transferred
to Buffer. Otherwise, GetData returns true.

Note:GetData cannot be used to read data from BLOB or memo fields. To
read BLOB data, use the stream returned by the dataset's
CreateBlobStream method or the BLOB field's SaveToStream method.
