For example, a sample question might ask you to add three months to a specific date. The course presents options like `SELECT ‘2023-04-10’ + INTERVAL ‘3 months’;` or `SELECT DATE_ADD(‘2023-04-10’, INTERVAL 3 MONTH);` (which is more common in MySQL, but often included for comparative learning). Understanding the correct PostgreSQL syntax, such as `SELECT ‘2023-04-10’::DATE + INTERVAL ‘3 months’;`, is precisely the kind of granular knowledge this course aims to reinforce.
