VIEWing your query

You've worked hard to create the below SQL query: 

SELECT DISTINCT author AS unique_author
FROM books;

What if you'd like to be able to refer to it later, or allow others to access and use the results? The best way to do this is by creating a view. Recall that a view is a virtual table: it's very similar to a real table, but rather than the data itself being stored, the query code is stored for later use.

  • Add a single line of code that saves the results of the written query as a view called library_authors.
