ExecuteScalar with Oracle

[Stan SR]

Hi,

I m trying to get the last added sequence from an Oracle table with
executeScalar, but it seems I m doing something wrong.
Here's my query (that I use with commandType.Text (not a storeproc).

DECLARE curval number;
BEGIN INSERT INTO UTILISATEUR_GADGET
(uiduser,instance,couleur,gadget,idpage,colonne,li gne,param,dateupdate)
values ('B020964','',0,'feedrss.htm',4,2,0,'',TO_TIMESTAM P('22/02/2008
07:42:40','DD/MM/YYYY HH24:MI:SS'));
select UTILISATEUR_GADGET_SEQ.currval into curval from DUAL; END;

But I always get back a 0 as value (the record is added)

Any help ?

In the code you show I don't see where you get the "next" value from
that sequence. So could it be that the value 0 is correct for the code?
