6    101           smith    Exam
7    101           smith    Exam
8    101           smith    Exam

Answer 1

好吧，查询返回了不同的结果。

如果您指的是EmployeeId, NAME and Department，那么您可以尝试类似

的内容

SELECT  DISTINCT
        s.EmployeeId,
        e.NAME,
        e. Department
FROM    SelfAnswers AS s Inner Join 
        Employee As e   ON  s.EmployeeId=e.EmployeeId
