Hexadecimal sequence in Oracle

I would like to generate 16 char length hex decimal value as sequence. My database is Oracle and would like to know is it possible to do so? I checked the SEQUENCE in Oracle but I think its only for numericals.

Any idea would be great help.

Thanks in advanc开发者_如何学Pythone,

Yes, Oracle sequences are integers.

In order to use a sequence to generate a 16 character length hexadecimal value, you need to use TO_CHAR:

TO_CHAR(your_sequence.NEXTVAL,'XXXXXXXXXXXXXXXX')
