A Guide to SQL
- Write SQL queries, using "Movie Rental Database"arrow_forwardI got a question on number 1 through 3 from MySQL. these are the steps: Write the SQL code that will list all of the drivers in the database that have been issued tickets. Write the SQL code that will list all of the drivers in the database that have not been issued tickets. Write the SQL code that will list all of the drivers in the database that have been issued tickets, along with the total number of tickets that they have been issued and the total amount of fines that they have been charged. Do you guys know how to do these steps?arrow_forwardoracle SQL Consider the following schema: Publisher (name, phone, city), PK: name. Book (ISBN, title, year, published_by, previous_edition, price), PK: ISBN, FK: published_by refs Publisher, previous_edition refs Book. Author (SSN, first_name, last_name, address, income), PK: SSN. Write (aSSN, bISBN), PK: (aSSN, bISBN), FK: aSSN refs Author, bISBN refs Book. Editor (SSN, first_name, last_name, address, salary, works_for, book_count), PK: SSN, FK: works_for refs Publisher. Edit (eSSN, bISBN), PK: (eSSN, bISBN), FK: eSSN refs Editor, bISBN refs Book. Author_Editor (aeSSN, hours), PK: aeSSN, FK: aeSSN refs Author, aeSSN refs Editor. Please be advised that answers such as SELECT title from Book WHERE ISBN IN (SELECT aSSN from Write WHERE COUNT(aSSN)>3) will work as the question refers to books that have more than 3 authors, meaning 3 or more authors worked on the same book. so not aSSN so it would need to be something like bISN>3 Give the title of those books that have more than 3…arrow_forward
