In this project, we'll investigate a database by using joins and find answers for questions like :

  • What day of the week do most users register on?
  • Which users have not posted any photos?
  • Which users liked every single photo on the clone website?

Authors

Tables that we'll create:

  • users
  • photos
  • follows
  • comments
  • likes
  • tags
  • photo_tags

Warnings

These two queries are used to fix a problem with the group by function, use them if needed

-- SET @@sql_mode='';

-- SET @old_sql_mode=@@sql_mode;
