SQLite help: --7. Update relation record by swapping enrollments in CSE132A and CSE132B in Fall 2016, without explicitly naming the students involved. That is, all students enrolled in CSE132A should be dropped from that class and enrolled in CSE132B, and conversely. You may use several update commands if needed.

This is an individual assignment. Please review the academic integrity olicy and contact the instructor or TA if you have any questions. The university registrar database has the following schema: student: sid (string) course: cid (string) prerequisite: cid (string), precid (string record: sid (string), cid (string), qtr (string), year (integer), grade (integer) Relation student provides the ids of all students enrolled in the university, and course provides all offered courses. Relation prerequisite provides the prerequisites pre cid for each course cid. Relation record indicates which courses were taken by each student in a given year and quarter (F, W, S), and the grade obtained (for simplicity, grades are provided as integers 4,3, 2, 1,0, corresponding to A, B, C, D, F). Assume that a class can only be taken once. Note that students may have gaps in enrollment, i.e. they need not take courses every quarter. In addition, the following hold: . sid is the primary key of student . cid is the primary key of course . cid, pre-cid} is the primary key of prerequisite; cid and pre.cid are foreign keys referencing course. {sid, cid, qtr, year is the primary key of record (so grades are unique for each course taken by a student in a given year and quarter), sid is a foreign key referencing student and cid is a foreign key referencing co urs e . 7.
