ข้อกำหนดเบื้องต้นที่ฉันปฏิบัติตามสำหรับ SOCADMIN 570 มีอะไรบ้าง ไม่จำเป็นต้องใช้ตารางทั้งหมด
What are the prerequisites that I have met for SOCADMIN 570 ?It is not neccessary to use all the tables.
 comment_instructor:  instructor_id [ int]  student_id [ int]  score [ int]  comment_text [ varchar] 
SELECT DISTINCT COURSE_0.department, COURSE_0.name, COURSE_0.number FROM course AS COURSE_0, course AS COURSE_1, course_prerequisite, student_record WHERE COURSE_0.course_id = course_prerequisite.pre_course_id AND COURSE_1.course_id = course_prerequisite.course_id AND COURSE_1.department = 'SOCADMIN' AND COURSE_1.number = 570 AND student_record.course_id = COURSE_0.course_id AND student_record.student_id = 1
