Combining RAG with SQL and APIs
Many questions require exact structured values plus an explanation. Fetch current order status from an authorized API, then retrieve policies or troubleshooting documents for context. Do not execute arbitrary model-generated SQL with broad credentials. Use typed tools, parameterized queries, read-only roles, row limits, and validation.
Keep structured data timestamps and document citations distinct in the final answer.
Implementation example
Question -> authorized order API -> exact status
-> document retrieval -> explanation
-> combine with provenance and timestamps💡 Use the right retrieval method for each evidence type.
Key Takeaways
- Inspect the relevant pipeline stage instead of guessing.
- Preserve source provenance, versions, and access scope.
- Measure quality on representative queries.
