Retrieves the current value of a field into a buffer.

Pascal
function GetBlobFieldData(FieldNo: Integer; var Buffer: TBlobByteData): Integer; override;
C++
virtual __fastcall int GetBlobFieldData(int FieldNo, TBlobByteData Buffer);
Description

Most applications do not need to call GetBlobFieldData, this method being used internally by descendants of TCustomADODataSet. GetBlobFieldData reads blob data from the field specified by FieldNo into a Buffer. The buffer is a dynamic array of bytes, so that it can grow to accommodate the size of the BLOB data. GetBlobFieldData returns the size of the buffer.
