If you don't care about the rest of the values being +1 from each other, you could create the sequence with an INTERVAL of 20. Other than that, you would probably have to create your own "sequence" generator. Another alternative would be a function like this: get nextval as x set sequence to x+20 get nextval as y repeat if y != x+20 (i.e. someone else grabbed a value) - -- Greg Sabino Mullane greg@turnstep.com PGP Key: 0x14964AC8 200401150746 -----BEGIN PGP SIGNATURE----- iD8DBQFABovdvJuQZxSWSsgRAnxeAKCWK3tFCE3u8NfXG5LG3H0smDLyhACglrr7 08ke6k8B8MSKVipRb2aSWQg= =PSzM -----END PGP SIGNATURE-----
