I have a cursor which returns two values: one which I will use (and therefore will assign to an out variable) and another which I’ve only had returned to make the ROWNUM thing work.

If I run the cursor as a query, it works as expected. But if I execute the procedure the out variable comes empty. Is my approach somehow not supported? I mean, returning two values but only using one of them?

Here is my procedure code: (Don’t delve too much on the query itself. It works, I know it’s a bit ugly but it works. It was the only way I found to return the second-last row)

procedure retorna_infos_tabela_164(i_nip in varchar,
                               o_CODSDPANTERIOR out number) is
cursor c_tabela_164 is
    select *
    from(
        select CODSDP,ROWNUM rn
        from
              (
                select NRONIP,CODTIPOMOV,CODSDP
                from TB164_HISTORICOMOVIMENTACOES
                where NRONIP = i_nip and
                CODTIPOMOV='S1'
                order by DTHMOV desc
              )
        )
    where rn=2;

    v_temp_nr number;

begin
    open c_tabela_164;
    fetch c_tabela_164 into o_CODSDPANTERIOR,v_temp_nr;
    close c_tabela_164;
end retorna_infos_tabela_164;

EDIT The way I’ve tried to run this procedure was by dbms_output.put_line(o_CODSDPANTERIOR) which didn’t work. Then I googled a little bit and saw I should TO_CHAR() my var first and then have it output. Didn’t work either.

    I’m sorry I’ve had you guys take the time to answer me when the answer was something to do with the tool I’m using. I hope all you guys have learnt something.

    The query does work for me at least, I’ve not come across any edge cases where it doesn’t work, but I haven’t tested it exhaustively.

    The problem was that TOAD, the tool I’m using to run the procedures, sometimes populates the procedures with the parameters I tell it to but sometimes it doesn’t. The issue here was that I was trying to execute the procedure with no parameters, yielding no results…

    Lesson Learnt: double check the generated procedure code when you run a Procedure using Right Click > Run Procedure on TOAD version 9.
