How to Build an AI SQL Assistant with Vanna

Allowing non-technical users to query your data is a massive productivity boost. Vanna AI is a framework that uses RAG to translate English questions into perfectly formatted SQL queries.

Training on Your Schema

Vanna works by "learning" your database structure. You feed it your DDL (table definitions), documentation, and historical queries. The system then uses this context to generate SQL that respects your specific business logic and relationships, which a generic LLM would likely get wrong.

A Self-Improving Feedback Loop

One of Vanna's strongest features is its ability to learn from user corrections. If the AI generates an incorrect query and a human fixes it, that "correct" query is stored in the knowledge base. Over time, the AI becomes a highly accurate, specialized expert on *your* specific data warehouse.
