How to submit

  1. After running your queries in DBeaver, make sure to save them in one script file.

  2. Make sure the file is of type .sql

  3. Add task items as comments before your queries so it is easier to review:

-- 1. How many tasks are in the task table?
SELECT ... FROM ...;
-- 2. How many tasks in the task table do not have a valid due date?
SELECT ... FROM ...;
-- etc...

  1. Create a pull request in your assignment repo as usual.
