try with cast

select cast(00000001 as string)

if you are using direct numbers like  select 00000001 or something like this
try (select '00000001' as string) as number

are you walter sanchez?

thanks for the suggestion, but is it possible to generate a sequence with all the digits from the very beginning? for example:

CREATE SEQUENCE seq_code;

CREATE TABLE table1 (
      SequenceNum      integer default nextval('SequenceNum'),
      Field1            varchar(8)
);

for the 'SequenceNum' field under table1, i would like the sequence generated with all of the 8 digits.

thanks.

lgmm, nope, i'm not walter.

Hi, WSanchez,

your solution is:

select right(str(100000000 + SequenceNum,9),8)
