Update History

June 8, 2026 — Foundations Refined

We reviewed the early Phexorivaro SQL materials and improved several foundational sections covering database structure, basic queries, filtering, and sorting. Explanations were reorganized for a clearer learning sequence, and selected examples were adjusted to make the relationship between query parts easier to follow.

July 28, 2026 — Curriculum Expanded

The curriculum was updated with broader coverage of joins, grouped data, subqueries, common table expressions, and analytical SQL concepts. We also refined the progression between course tiers so each stage connects more clearly with the topics introduced before it.

September 15, 2026 — Structure and Review Updated

We completed another review of the Phexorivaro SQL course collection, with updates to examples, exercises, module organization, and review sections. The latest version also improves consistency across the full curriculum, from foundational SQL topics through schema organization, indexing concepts, and wider query workflows.
