What problem does it solve?

Parameterized, context-aware, observable database access in Go—without relying on ORMs or opaque abstractions, enabling safer and clearer data interactions.

Core Features & Use Cases

• Parameterized queries and explicit error handling to distinguish not-found and real failures.
• Context propagation for every DB operation and consistent use of QueryContext / GetContext / ExecContext.
• Transaction patterns with BeginTx, proper rollback handling, and selective isolation levels.
• NULL handling with pointer fields and proper struct scanning for sqlx and pgx.
• Testing patterns: unit tests with mocks and integration tests against a real database.

Quick Start

Create a minimal Go data layer using sqlx that queries a PostgreSQL table with parameterized SQL and returns results.
