Natural-language SQL breaks quietly when schema context goes stale
Natural-language SQL generation tools can produce incorrect results when the underlying database schema changes without the tool being updated. This "schema drift" can lead to subtly wrong answers that are difficult to detect, even if the generated query runs successfully. To mitigate this, database servers should incorporate schema drift detection, including versioning of schema context with query results, metadata refresh timestamps, and hashing of database migrations.
