Text to SQL is a technique that converts natural language queries into SQL queries that can be executed by a database. Although large language models (LLMs) can understand and transform natural language, creating accurate SQL for your own schema can be challenging. Enter Vanna, an open-source Python retrieval-augmented generation (RAG) framework for SQL generation. Vanna works in two steps: first you create embeddings with the data definition language statements (DDLs) and sample SQLs for your schema, and then you ask questions in natural language. Although Vanna can work with any LLMs, we encourage you to assess NSQL, a domain-specific LLM for text-to-SQL tasks.
