Fwd: Question

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
