What is the difference between spooling in Oracle SQL Developer and saving query results?

Spooling in Oracle SQL Developer is a feature that allows you to save the output of a SQL query to a file. This feature captures the output of the query as it is displayed on the screen and saves it in a file on your computer.

On the other hand, saving query results in Oracle SQL Developer allows you to save the results of a query directly within the SQL Developer tool itself. This feature saves the output of the query within the tool, so you can access it later without having to re-run the query.

In summary, spooling saves the output of a query to a file on your computer, while saving query results saves the output within the SQL Developer tool for easy access later.
