How to insert into a table with just one IDENTITY column

Question

(Came up with this question in the course of trying to answer this other one)

Consider the following MS-SQL table, called GroupTable:

GroupID
-------
1  
2  
3  

where GroupID is the primary key and is an Identity column.

How do you insert a new row into the table (and hence generate a new ID) without using IDENTITY_INSERT ON?

Note that this:

INSERT INTO GroupTable() Values ()

... wont work.

edit: we're talking SQL 2005 or SQL 2008 here.

Answer 1

Can you try using a Sequence or something similar? Where you select from a Sequence and it will give you the next value in the sequence.

Answer 2

This should work:

INSERT INTO GroupTable DEFAULT VALUES

Answer 3

Here you go:

INSERT INTO GroupTable DEFAULT VALUES
