Cursor-based Pagination Query
Implement cursor-based (keyset) pagination in SQL — faster than OFFSET for large tables.
sql
-- First page
SELECT id, title, published_at
FROM modules
WHERE is_published = true
ORDER BY published_at DESC, id DESC
LIMIT 20;
-- Next page (pass last row's values as cursor)
SELECT id, title, published_at
FROM modules
WHERE is_published = true
AND (published_at, id) < ('2025-03-15 10:00:00', 42)
ORDER BY published_at DESC, id DESC
LIMIT 20;Prerequisites
- PostgreSQL >= 12 or MySQL >= 8
Pro Tips
- → Encode cursor as base64(JSON({published_at, id})) in your API.
