Database transactions in Go without an ORM require using BeginTx with proper rollback handling and selective isolation levels. This approach enforces explicit error handling and context propagation for every transaction operation to ensure safe data interactions.

Handling NULL values in sqlx involves using pointer fields within your structs for proper scanning. This avoids opaque abstractions and allows clear, explicit data interactions by directly mapping nullable database columns to Go pointers.

Context propagation in pgx requires consistent use of QueryContext, GetContext, and ExecContext methods for every database operation. This ensures your queries are observable, context-aware, and safely cancellable without relying on ORMs.

Yes, this approach applies to codebases using database/sql with either sqlx or pgx. It enforces parameterized queries, explicit error handling to distinguish not-found results from real failures, and proper row closing across both libraries.

Testing Go database access involves unit tests with mocks and integration tests against a real database. This strategy ensures your parameterized queries and transaction patterns perform safely and observably without ORM dependencies.
