SQL: Why does 'S%' Die?

For some reason ANY any alphabet works EXCEPT S

select * from tContact where UPPER(LASTNAME) LIKE 'A%' AND CONTACTSTATUSID = 1 ORDER BY LASTNAME ASC, FIRSTNAME ASC

Code (markup):

^above works but once you put S in there, it dies

(Does not work)

select * from tContact where UPPER(LASTNAME) LIKE 'S%' AND CONTACTSTATUSID = 1 ORDER BY LASTNAME ASC, FIRSTNAME ASC

Code (markup):

Why is that? Is there a work-around?

 

like is not case senstitve, also, never do Select *

Do:

SELECT tContact.FieldName1, tContact.Fieldname2
FROM tContact
WHERE (LastName Like 'S%') AND (ContactStatusID = 1)
ORDER BY LastName, FirstName
