Problem Statement: There are three tables: Student Table, Program Table, and Scholarship Table as shown belowWrite an SQL query to list STUDENT_ID who does not get Scholarship. Student Table STUDENT_ID FIRST_NAME LAST_NAME GPA ENROLLMENT_DATE MAJOR 201 Shivansh Mahajan 8.79 2021-09-01 09:30:00 Computer Science Program Table STUDENT_REF_ID PROGRAM_NAME PROGRAM_START_DATE 201 Computer Science 2021-09-01 00:00:00 Scholarship Table STUDENT_REF_ID SCHOLARSHIP_AMOUNT SCHOLARSHIP_DATE 201 5000 2021-10-15 00:00:00 AnswerLanguagejava1select s.student_id from student s left join PREVNEXT
Solution
Sure, here is the SQL query to list the STUDENT_ID who does not get a Scholarship:
SELECT s.STUDENT_ID
FROM Student s
LEFT JOIN Scholarship sch
ON s.STUDENT_ID = sch.STUDENT_REF_ID
WHERE sch.STUDENT_REF_ID IS NULL;
This query works by performing a LEFT JOIN on the Student and Scholarship tables using the STUDENT_ID and STUDENT_REF_ID fields. The WHERE clause then filters out the students who have a scholarship (where STUDENT_REF_ID is not NULL), leaving only the students who do not have a scholarship.
