The author argues against treating Text-to-SQL as a foolproof solution, advocating for robust data governance and architectural patterns like a Semantic Layer or Frozen Schema to mitigate risks. These approaches aim to create reliable systems rather than expensive, unpredictable hallucination engines by imposing infrastructure-level constraints. AI

    <p>Last June, a junior analyst pushed a "helpful" GenAI assistant to our internal Tableau-connected lakehouse. Within forty minutes, the agent generated a <code>SELECT *</code> across a 40-terabyte partitioned table joined against a cross-region S3 bucket. The query didn't just f…
