Еженедельное расписание с SQL

Question

Мне нужен еженедельный планировщик для студентов.

• Строки - 12 часов (08: 00-20: 00), столбцы
• - 6 дней (понедельник-суббота).
• Студент проходит курс обучения в понедельник с 9 по 11 и во вторник с 11 по 14.
• Другие будут показаны пустыми.

Могу ли я создать запрос (матрицу), подобный этому, только с помощью SQL?

Мой текущий запрос выглядит так:

SELECT courseName, courseDay, courseStartHour, coursEndHour 
FROM courses WHERE studentId = 1

Вот что я хочу:

У меня было это с Pivot:

Один и тот же час может включать несколько курсов.(максимум 2)

Примечание: у нас есть Oracle 11g.

Образец (упрощенный) данных:

CREATE TABLE StudentCourses ( courseCode varchar2(8) NOT NULL,  courseName varchar2(64) NOT NULL,  day number(10),  startHour number(10),  endHour number(10));

INSERT INTO StudentCourses (courseCode, courseName, day, startHour, endHour ) VALUES ( 'ADV 352','Advertising Copywriting','1','9','11' );
INSERT INTO StudentCourses (courseCode, courseName, day, startHour, endHour ) VALUES ( 'ADV 352','Advertising Copywriting','1','11','13' );
INSERT INTO StudentCourses (courseCode, courseName, day, startHour, endHour ) VALUES ( 'ADV 332','Positioning Strategy in Advertising','2','9','12' );
INSERT INTO StudentCourses (courseCode, courseName, day, startHour, endHour ) VALUES ( 'COMM 324','Persuasion and Perception','2','14', '17' );
INSERT INTO StudentCourses (courseCode, courseName, day, startHour, endHour ) VALUES ( 'ADV 312','Corporate Communications Practicum','3','14','17' );
INSERT INTO StudentCourses (courseCode, courseName, day, startHour, endHour ) VALUES ( 'ADV 302','Strategic Media Planning','4','9','11' );
INSERT INTO StudentCourses (courseCode, courseName, day, startHour, endHour ) VALUES ( 'ADV 302','Strategic Media Planning','4','11','13' );
INSERT INTO StudentCourses (courseCode, courseName, day, startHour, endHour ) VALUES ( 'ADV 412','Case Studies in Advertising','4','13','15' );
INSERT INTO StudentCourses (courseCode, courseName, day, startHour, endHour ) VALUES ( 'ADV 411','Advertising Photography','4','14','16' );
INSERT INTO StudentCourses (courseCode, courseName, day, startHour, endHour ) VALUES ( 'ADV 412','Case Studies in Advertising','4','15','17' );
INSERT INTO StudentCourses (courseCode, courseName, day, startHour, endHour ) VALUES ( 'ADV 411','Advertising Photography','4','16','18' );

Answer 1

Вот более простой вариант.

WITH TEMP AS(SELECT LEVEL+7 AS HR  FROM DUAL CONNECT BY LEVEL <= 12)
SELECT TEMP.HR AS "HOUR",
       CASE WHEN TEMP.HR BETWEEN 9 AND 11 THEN 'X' ELSE NULL END AS MON,
       CASE WHEN TEMP.HR BETWEEN 11 AND 14 THEN 'X' ELSE NULL END AS TUE,
       NULL AS WED,
       NULL AS THU,
       NULL AS FRI,
       NULL AS SAT,
       NULL AS SUN
       FROM DUAL, TEMP

select * from tab
