QUERIES Queries must be written to support the functionality of application: • All information about courses which is currently active. • All information about courses which is currently not active. • Text book, requisites, category or department of a course. • Maximum version of the courses.

Queries • Selecting Maximum Course Version Query SELECT tblCourseVersions.Code, Max(tblCourseVersions.Version) AS MaxOfVersion FROM tblCourseVersions GROUP BY tblCourseVersions.Code; • Selecting All Inactive Course Versions SELECT [tblCourseVersions].[Code],[Version], [PassingGrade], [AttendencePolicy], [Credits],[Hours], [ChangeReson],[PurposedChangeDate], [ActualChangeDate], [Status] FROM tblCourseVersions WHERE ([Status])<>"Active") • Selecting Text Book for Courses SELECT tblCourseTextBooks.Code,ISBN_No, Title,.Edition,Author,Publisher, Year FROM tblTextBooks INNER JOIN tblCourseTextBooks ON tblTextBooks.ISBN_No = tblCourseTextBooks.ISBN_No;
