Insert into propertybagid default values

INSERT T DEFAULT VALUES 

Or to insert multiple rows (up to 2048 at a time using the spt_values table)

SET IDENTITY_INSERT t ON
INSERT INTO t (id) 
SELECT Number + COALESCE(IDENT_CURRENT('t'),0) + 1
FROM master.dbo.spt_values
where type='p' and number < 2048
SET IDENTITY_INSERT t OFF

INSERT INTO <tablename> DEFAULT VALUES;
