Please solve Question 7 using the SQL command 'NOT EXISTS'.

Other relative info includes the data tables below:

TABLE `Streams` (
  `customer` int NOT NULL,
  `moviePrefix` char(4) NOT NULL,
  `movieSuffix` char(4) NOT NULL,
  `timestamp` timestamp NOT NULL,
  `duration` int NOT NULL

TABLE `Previews` (
  `customer` int NOT NULL,
  `moviePrefix` char(4) NOT NULL,
  `movieSuffix` char(4) NOT NULL,
  `timestamp` timestamp NOT NULL

TABLE `Movie` (
  `prefix` char(4) NOT NULL,
  `suffix` char(4) NOT NULL,
  `name` varchar(255) NOT NULL,
  `description` text NOT NULL,
  `rating` enum('G','PG','M','MA15+','R18+') NOT NULL,
  `releaseDate` date DEFAULT NULL

TABLE `Customer` (
  `id` int NOT NULL,
  `name` varchar(255) NOT NULL,
  `dob` date NOT NULL,
  `bestFriend` int DEFAULT NULL,
  `subscriptionLevel` varchar(25) NOT NULL

A relational database has been setup to track customer browsing activity for an online movie streaming service called SurfTheStream. Movies are identified by a unique code that consists of a four-character prefix and four-digit suffix. Additionally, each movie is assigned a content rating which must be one of the following options: "G", "PG", "M", "MA15+" or "R18+". The first time a customer previews a movie is captured by the database. Customers may preview a movie before they stream it, however, they cannot preview a movie after they have started to stream it. You may assume "Duration" refers to the time in seconds a customer has spent streaming a particular movie after the "Timestamp". A simplified version of their database schema has been provided below including foreign key constraints. You should consult the provided blank database import file for further constraints which may be acting within the system. Relational Schema Customer (id, name, dob, bestFriend, subscriptionLevel] Customer.bestFriend references Customer.id Customer.subscriptionLevel references Subscription.level Movie (prefix, suffix, name, description, rating, releaseDate] Previews (customer, moviePrefix, movieSuffix, timestamp] Previews.customer references Customer.id Previews.(moviePrefix, movieSuffix} reference Movie.(prefix, suffix} Streams (customer, moviePrefix, movieSuffix, timestamp, duration] Streams.customer reference Customer.id Streams.{moviePrefix, movieSuffix} reference Movie.{prefix, suffix} Subscription [level]
