I was wondering is it possible in SQL Server 2005 to insert a autonumber field similar to what's done in access?

INSERT INTO [robert_thurs_12102009]
[supplier_id], [supplier_name]
FROM
[robert_thurs_12102009]
VALUES
(supplier_seq.NEXTVAL, 'K Foods');

am I headed down the right path?

That's not how it works in SQL Server. Here's an example:

CREATE TABLE t1 (c1 int IDENTITY(1, 1), c2 varchar(5))

INSERT INTO t1 (c2) VALUES ('Test')

SELECT * FROM t1

DROP TABLE t1

alter table add id int identity (1,1) not null

create table a
(
id int identity (1,1) not null ,
...
)

It can take any exact numeric - decimal, bigint, int, smallint, ...

Remember also to put a unique index on the column as it is not guaranteed to be unique.
