Courses Plus Student 1,883 PointsEnter a review for E.T. Use a username and review of your choosing.
The scheme for reviews doesn't have a title column, only a column for the movie ID.
This task is asking me to insert a review into that data base for ET.
Say I didnt have the movie ID? Or I just didnt want to look it up just so I could insert the value appropriately into the reviews data base.
Is there some way to link the two tables and say "Insert a review for ET by inserting the id that the movie is linked to, then insert username, review, and rating?"
Maybe that's asking two much for one line of code. but I feel like there has to be a simpler way to accomplish this.
