procedure TMainForm.Button2Click(Sender: TObject);
var
oMetaIntf: IFDPhysConnectionMetadata;
begin
// get client and server versions
oMetaIntf := FDConnection1.ConnectionMetaDataIntf;
try
ShowMessage(Format('Client version: %.10d; Server version: %.10d',
[oMetaIntf.ClientVersion, oMetaIntf.ServerVersion]));
finally
oMetaIntf:= nil; // always release the Interface before you close the connection
end;
