Problem with the SELECT statement

I wanted to create a view from ms. access. So I used the following code

CREATE VIEW  Teaches (DayId,DayName,Period,SubName) AS
SELECT D.DayId,D.DayName,P.Period,S.SubName
FROM Day AS  D,Period AS  P, Subject AS  S,Teaching AS  T
WHERE T.DayNo=D.DayId AND T.PeriodNo=P.PerId AND T.SubNo=S.SubId
ORDER BY D.DayId ASC;
