Is this normal behaviour? Some details: It's a D2005 dbexpress application with a FireBird1.5 server. My remote DM has a DataSetProvider linked to a SQLStoredProc. My client app can correctly fetch the params. I have 1 input and 1 output param. ==CODE== Mycds.Params[0].AsInteger := IdNr; //Params.count = 2 Mycds.Execute; //sets Params.count = 1 Result := Mycds.Params[1] ->List index out of bounds. Result := Mycds.Params[0] //correct Output param Ok, I can workaround by calling FetchParams everytime but I assume this is not how its supposed to work. Can anyone explain this? Regards, Tom.

Just like you my only solution was to call fetch params. Couldnt find a pattern to reproduce the problem and report it. Let us know if you find out the cause of it. Thanks in advance. Att.

But this workaround obviously only works if you can modify the SP. Peter Esteban Pacheco wrote: Quote: Hi guys, Finally i hear someone with the same problem.
