dbt column-level lineage maps each dbt model column back to the source columns, expressions, filters, joins, and transformations that produced it. Learn why compiled SQL matters and where catalogs need semantic lineage.
Learn why LLM-generated SQL needs semantic validation: catalog binding, name resolution, type checks, joins, permissions, and repair feedback.
Prompt rules can improve LLM-generated SQL, but they cannot prove a query is safe, authorized, semantically valid, or auditable. Production Text-to-SQL needs deterministic SQL validation before execution.
