Display row from a table if a condition in another table is met
I have two tables, students and applications. A student has an ID and a name, and can make many applications. The applications table has an ID, the student ID as a FK, and an APPLICATION_STATUS.
I want to display all students where none of their applications have 'APPLICANT ACCEPTED OFFER' in APPLICATION_STATUS.
I've tried:
SELECT STUDENTS.FIRST_NAME ||' '||STUDENTS.LAST_NAME "Student Name"
FROM STUDENTS
JOIN APPLICATIONS ON STUDENTS.SRN = APPLICATIONS.SRN
WHERE APPLICATION_STATUS != 'APPLICANT ACCEPTED OFFER';
This is what I've tried so far, but instead of displaying the students that haven't accepted an offer, it is showing all applications that were not accepted.

You don't need a join, use not exists
SELECT STUDENTS.FIRST_NAME ||' '||STUDENTS.LAST_NAME "Student Name"
FROM STUDENTS
WHERE not exists ( select 1 from
APPLICATIONS where STUDENTS.SRN = APPLICATIONS.SRN
And APPLICATION_STATUS = 'APPLICANT ACCEPTED OFFER');
