How to save a report FR4 into a firebird blob field?

At Fr2.5 was a function 'savetoblobfield' a it was very easy to save the report in a blob field in the firebird database.
At Fr4 I have not found a function to do this . Can anyone tell me how to implement a 'savetoblod' in Fr4 because I cannot upgrade my reports from 2,5 to 4 since I cannot save them in blob

Thanks

At Fr4 you can use function SaveToStream.

To save:

var 
  f: TFileStream;
begin
  f := TFileStream.Create(fileName, fmOpenRead);
  ...
  ParamByName('YOUR_BLOB_FIELD').LoadFromStream(f);
  ExecSQL;
  ...
  f.Free;
end;

To load:

var 
  report_blob: TBlobField;
  report_stream: TStream;
begin
  //After querying
  ...
  //In case you use TClientDataSet
  report_blob := yourClientDataSet.FieldByName('YOUR_BLOB_FIELD') as TBlobField;

  report_stream := TStream.Create;
  report_stream := yourClientDataSet.CreateBlobStream(report_blob, bmRead);
  
  frxReport.LoadFromStream(report_stream);
  ...  
end;

It works fine for me.
