Episode 11 — Use ANSI SQL Intentionally: Standards, Portability, and Practical Tradeoffs
This episode explains why ANSI SQL matters for DS0-001 even if you spend most of your time in one vendor platform, because the exam often tests your ability to separate standard behavior from product-specific extensions. You’ll review what “portable SQL” really means in practice, including common areas where engines diverge, such as date functions, string handling, limit and pagination syntax, null ordering, and upsert patterns. We’ll discuss when standard SQL is the safer choice for long-lived applications, migrations, and multi-database environments, and when a vendor feature is justified because it improves reliability, performance, or administrative simplicity. You’ll also work through scenario-style decisions, like troubleshooting an application that breaks after a database change, or designing queries intended to run across dev, test, and production environments that are not perfectly identical. By the end, you should be able to read a question, recognize “portability risk,” and choose an approach that balances correctness with maintainability under real operational constraints.
