How to Save .qrp into database blob field

Hi ,

I want to save .qrp direct into database, without save it in file first
and in next step I want to read it direct to TQRPreview.

I m loading file with kode:

qrPreviewMain.QRPrinter:=TQRPrinter.Create;
qrPreviewMain.QRPrinter.Load('01044.qrp');
qrPreviewMain.PageNumber := 1;

but I dont know how to read data direct from blob field into
TQRPreview.

Thanks for help
