Feature Tasks

Don't forget to set your conString!

As a developer, I want to utilize SQL queries so that I can join data together in the database and access it based on specific criteria.

Write a SQL query to join all data from articles and authors tables on the author_id value of each when the articles are retrieved.
Write a SQL query to create a new article.
- Insert an author and pass the author and authorUrl as data for the query. On conflict, do nothing.
- In the second query, add the SQL commands to retrieve a single author from the authors table. Add the author name as data for the query.
- In the third query, add the SQL commands to insert the new article using the author_id from the second query. Add the data from the new article, including the author_id, as data for the SQL query.
Write a SQL query to update an author record and article record.
- Remember that the articles now have an author_id property, so we can reference it from the request.body. Add the required values from the request as data for the SQL query to interpolate.
- After the author has been updated, you will then need to update an article record. Remember that the article records now have an author_id, in addition to title, category, publishedOn, and body. Add the required values from the request as data for the SQL query to interpolate.
Once you complete the above feature tasks, follow the instructions in the adjacent 09-CRUD-testing.md doc to verify that everything works.
