I have a class project where I'm responsible for coming up with the following query and I'm not sure where to start... Type of... If/then statement, while loop and so on...
"Write a query that finds users who are similar to a given user (target user), the id of the target user is an input parameter. Users are similar to the target user if they rate the same movies."
There are 3 databases in the project, movies, ratings and tags..
Need help!!
Thanks,
Sy
