Uploading images from client to database

Hello
I have a Server-Client program and I cannot save images to the database via the Client.

 TSQLRESIM = class(TOrm)
  private
    fscl: RawUTF8;
    fPicture:RawUTF8;//RawBlob;
    fdel: byte;
  published
    property SCLID  : RawUTF8 read fscl write fscl;
    property PICTURE    : RawUTF8{ RawBlob} read fPicture write fPicture;
    property DELETED: byte read fdelwrite fdel;
  end;


    MAKRSM:= TSQLRESIM.CREATE;

   MAKRSM.SCLID:=x;

         r:=TRawByteStringStream.Create();
         r.LoadFromFile(OPD.FileName);  // OPENDIALOG
         r.Position:=0;
 
         MAKRSM.PICTURE:=StringToUtf8(r.DataString);

        if aClient.orm.Add(MAKRSM, True) = 0 then
        showmessage('OK');

SCLID ok but PICTURE empty. i try rawblob PICTURE empty

Re: Uploading images from client to database

It is as documented. https://synopse.info/files/html/Synopse … #MNDX_1517
RawBlob are not retrieved nor saved by default within the JSON transmitted to the server.
Use the dedicated BLOB methods, e.g. RetrieveBlobFields.
You can also use ForceBlobTransfert and similar methods.
