In applications that cannot tolerate duplicates it may be necessary to use DISTINCT. However, the query plan needed to support DISTINCT requires a sort, which is expensive. Therefore you should only use DISTINCT when duplicates are possible in the result set. Using the schema of Section 4.8, check the following queries to see if duplicates are possible. Explain your answer in each case.

a. ``` SELECT S.Name FROM Student S WHERE S.Id LIKE ’1’ ``` b. ``` SELECT S.Id FROM Student S, Facu lty F WHERE S.Address = F.Address ``` c. ``` SELECT C.CrsCode, COUNT(*) FROM Transcript T GROUP BY T.CrsCode ``` d. ``` SELECT F.Name, F.DeptId, C.ClassTime, C.CrsCode, C.Semester, C.Year FROM Facu lty, Class C WHERE F.Id = C.InstructorId ``` e. ``` SELECT S.Name, F.Name, T.Semester, T.Year FROM Facu lty, Class C, Transcript T, Student S WHERE F.Id = C.InstructorId AND S.Id = T.StudId AND C.CrsCode = T.CrsCode AND C.SectionNo = T.SectNo AND C.Year = T.Year AND C.Semester = T.Semester ```
