I have to assume you aren’t showing me the whole picture. It also isn’t t-sql syntax. So, using t-sql, you want something like:

declare limit number;
declare nextval number;
begin
SET @limit = 72011080;
Select @nextval = SEQTITRES.nextval from dual;
while @nextVal < @limit
loop
Select @nextval = SEQTITRES.nextval from dual;
end loop;
end;

Could you please help me with this sql procedure? I always got an error message when executed, at the line with while. The error message is after the procedure:

declare
limit number;
begin
limit := 72011080;
while (select SEQTITRES.nextval from dual) < limit
loop
select SEQTITRES.nextval from dual;
end loop;
end;

ERROR MESSAGE:
PLS-00103: Encountered the symbol “SELECT” when expecting one of the following:

( – + case mod new not null others
avg

Thanks in advance,
