สำหรับวิชาเอก CS มีชั้นเรียนใดบ้างในฤดูหนาวนี้ที่จะนับรวมในนั้น ?ไม่จำเป็นต้องใช้ตารางทั้งหมด
For a CS major , what classes are available this Winter that would count towards that ?It is not neccessary to use all the tables.
 student:  student_id [ int]  lastname [ varchar]  firstname [ varchar]  program_id [ int]  declare_major [ varchar]  total_credit [ int]  total_gpa [ float]  entered_as [ varchar]  admit_term [ int]  predicted_graduation_semester [ int]  degree [ varchar]  minor [ varchar]  internship [ varchar] 
SELECT DISTINCT course.department, course.name, course.number FROM course, course_offering, program, program_course, semester WHERE program_course.course_id = course.course_id AND program_course.course_id = course.course_id AND program.name LIKE '%CS%' AND program.program_id = program_course.program_id AND semester.semester = 'Winter' AND semester.semester_id = course_offering.semester AND semester.year = 2016
