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?
