Episode 30 — Verify Code Execution Against Requirements: Syntax, Logic, and Error Handling
This episode focuses on verifying database code execution against requirements, which DS0-001 tests through stored procedure behavior, migration scripts, query correctness, and failure handling under real operational constraints. You’ll learn to separate syntax validity from logical correctness, because code that runs without errors can still violate business rules, produce incomplete results, or create performance issues that show up only at scale. We’ll cover verification techniques such as testing with representative data, validating edge cases, comparing expected versus actual row counts, and reviewing execution plans to ensure the database is using the intended access path. Error handling will be treated as part of the requirement, including what should happen when constraints are violated, when inputs are malformed, or when downstream dependencies are unavailable, and how to make failures visible through logging, return codes, and transaction rollback behavior. Scenario examples will include a migration script that succeeds but silently skips rows due to conversion errors, a stored procedure that returns correct values but holds locks too long because of transaction scoping, and a query that passes functional tests but collapses under production cardinality. By the end, you should be able to recommend verification steps that match the risk, and choose the best corrective action when a prompt describes mismatched outputs, intermittent errors, or inconsistent behavior across environments.
