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.
