Identity, Default Values And Multiple Rows

Howdy all,
I've run into an interesting scenario that I can't seem to resolve.

We have a table that we are using to create sequence ids. It's literally a table with a single field with the identity value turned on.

create table ident (seq_id int identity(1,1) primary key NOT NULL)


If I want to grab a new sequence id, I can execute

INSERT INTO
ident
DEFAULT VALUES
SELECT scope_identity() AS seq_id


All is well and good. However, now let's suppose that instead of just one, I'd like to get a range of values.

If the table had one other field in it, I could do the following

create table ident2 (seq_id int identity(1,1) primary key NOT NULL, placeholder char(1))
GO
;
WITH RECORDS AS
(
SELECT
CAST('A' as char(1)) AS col1
UNION ALL
SELECT
char(ascii(col1) + 1)
FROM
RECORDS
WHERE
col1 < 'C'
)
INSERT INTO
ident2
OUTPUT
INSERTED.seq_id
SELECT
NULL
FROM
RECORDS


Can this be done if there is only the identity column and if so, someone care to educate me?
