Thank you. I almost get there.
But, if I inserted more values, the duplicate result will displays.
How to fix it?
INSERT INTO dbo.PatientInfo
VALUES ('06000248','08/02/2010','08/04/2010'),
('06000248','08/10/2010','08/12/2010'),
('06000248','08/20/2010','08/22/2010'),
('06000348','08/02/2011','08/04/2011'),
('06000348','08/10/2011','08/12/2011'),
('06000348','08/20/2011','08/22/2011');
