Dear Administrator:

I have a problem developing a ECPG program. I am making a programa using
FETCH, when the second row is sent the following message appear:

==>sqlcode [-213] msg[NULL value without indicator in line 1192.]

My select is:

EXEC SQL FETCH cursor_onlyweb
INTO
:t_token,
:t_institucion,
:t_usuario,
:t_horasistema,
:t_pan,
:t_prcode,
:t_amount,
:t_acqinst,
:t_source,
:t_datosreq;

Is it possible to use something similar to "isnull" in Oracle?

Thanks

Raul
