delphi - How to display BLOB Image from database in the TAdvStringGrid with the help of DataSet https://vigges.net/qa/?qa=1132506/

CreateBlobStream Picture LoadFromStream

delphi - How to display BLOB Image from database in the TAdvStringGrid with the help of DataSet
https://vigges.net/qa/?qa=1132506/

CreateBlobStream is creating a TStream object, not a TMemoryStream.
Since you do not want to write the JPG to the database you should use bmRead instead of bmReadWrite.
I am not used to SQLite, but you will have to make sure that you are using a suitable binary datetype (BLOB).

  JPG := TJpegImage.Create;
  Picture:= TPicture.Create;
  try
    st := results.CreateBlobStream(TBlobField(results.FieldByName('image')), bmRead);
    try
      JPG.LoadFromStream(st);
      Picture.Assign(JPG);
      sg.AddPicture(i,j,Picture,True,ShrinkWithAspectRatio,0,haLeft,vaTop);
    finally
      st.Free;
    end;
  finally
    JPG.Free;
    Picture.Free;
  end;

To ensure that the stored image is really a JPG you should write the JPG for testing with something like:

var
  ms: TMemoryStream;
begin
  ads.Open;
  ads.Append;
  ms := TMemoryStream.Create;
  try
    Image1.Picture.Graphic.SaveToStream(ms); // make sure having loaded a JPG
    ms.Position := 0;
    TBlobField(ads.FieldByName('image')).LoadFromStream(ms);
  finally
    ms.Free;
  end;
  ads.Post;
end;
