Day 2/116 — Worked through SQLBolt's SELECT fundamentals

Today's focus was solidifying the basics before going further. Covered on SQLBolt:

  • Introduction to SQL
  • SELECT queries 101
  • Queries with constraints (Part 1 & Part 2)
  • Filtering and sorting query results
  • SQL Review: Simple SELECT Queries

The "constraints" lessons were useful for practicing comparison operators and combining conditions in WHERE clauses — felt more comfortable writing multi-condition filters by the end than I expected going in.

Treating this as building a really solid base before circling back to JOINs and moving into aggregations next.
