- Use the given database to output the results of the following SQL queries: For these queries you need the student, takes, section, and teaches tables. I gave you all the resources you need. a.) SELECT ∗FROM Student AS S, Takes AS TWHERE S.ID = T.ID AND T.semester = 'Fall'; b.) (SELECT S.course id, S.semester, S.yearFROM Section AS SWHERE S.room number = 101)INTERSECT(SELECT T.course id, T.semester, T.yearFROM Teaches AS TWHERE T.ID = 83821); c.) SELECT T.course idFROM takes AS TWHERE T.semester IN(SELECT Z.semesterFROM teaches AS ZWHERE Z.ID = 10101)ORT.semester IN(SELECT X.semesterFROM section AS XWHERE X.time slot id ='B');My other instruction for SQL says: Create and test a stored procedure called checkin_transaction that processes a “checkin” transaction. When a book is checked in, the corresponding CHECKOUT record is updated to show the date it was checked in, and the Pat_ID attribute in the BOOK table is updated to NULL. The entire transaction (starting with START TRANSACTION; and ending with COMMIT;) should be in between the BEGIN and END statements of the stored procedure. You should be able to call the procedure with a statement like this, passing the values of the Book_Num, Pat_ID, and Check_In_Date to the procedure: CALL checkin_transaction(5243, 1170, ‘2017-04-30’) Do you guys know how?Write a SQL trigger to carryout the following action: If an account is deleted, then write a trigger to delete thedependent tuple(s) from the depositor table for every owner of the deleted account.

You must submit both your trigger function definition, and yourtrigger definition
