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          


        

Answer 1

Here you go:

INSERT INTO GroupTable DEFAULT VALUES

Answer 2

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 3

This should work:

INSERT INTO GroupTable DEFAULT VALUES 

Answer 4

It is possible to insert more than one row at a time.

For e.g., to insert 30 rows. INSERT INTO GroupTable DEFAULT VALUES GO 30

This will insert 30 rows by incrementing the identity column each time.
