简单 SQL 查询语句语法错误

Question

我是数据库新手，之前从未使用过 Access 2007，我在语法方面遇到了麻烦。这是信息

Teacher = [CourseN, Quarter,TeacherName]
Course = [CourseN,CourseName, Nunit)
Section = [CourseN, Quarter , DayTime,  RoomN]/ Examples of DayTime: M2:00AM, 
W4:50PM, and T8:00PM. Note that DayTime is represented as a string.
Student = [studentName, CourseN, Quarter]

问题

12.Use‘*’列出每门课程的CourseN、CourseName、Nunit、Quarter、TeacherName，按照CourseN升序、CourseName降序排列。

我的回答

 SELECT CourseN, CourseName, Nunit, Quarter, TeacherName 
 FROM *
 ORDER BY CourseN ASC, CourseName DESC;

但这给了我 FROM 子句错误，我该如何解决这个语法错误？还是我不能这样做？任何信息都会很棒，谢谢

编辑：我知道我可以这样做对吗？

SELECT C.CourseN, C.CourseName, C.Nunit, T.Quarter, T.TeacherName
FROM Course C, Teacher T
WHERE T.CourseN = C.CourseN
ORDER BY C.CourseN ASC, C.CourseName DESC;

Answer 1

您不能将 * 放在 FROM 子句中！您必须明确定义要使用的表。

再想一想：虽然您可以在 WHERE 子句中定义表之间的关系，但如果您在 FROM 子句中定义关系会更好（或至少更清楚），使用 INNER JOIN:

select c.courseN, c. courseName, c.Nunit, t.quarter, t.teacherName
from course as c
     inner join teacher as t on c.counrseN = t.courseN
