Chat with SQL
Executive Summary
Chat-with-SQL is an AI-powered conversational interface that lets users query relational databases using natural language instead of writing SQL manually. It connects securely to an existing SQL database and translates user intent into accurate, executable SQL queries, returning clear, human-readable answers in seconds. Rather than replacing databases or abstracting them away, Chat-with-SQL works directly on top of existing schemas. Users ask questions in plain English, and the system converts intent into precise SQL execution, bridging the gap between data and decision-making.
Challenges
Solution Overview
Chat-with-SQL provides a schema-aware AI agent that translates plain-language questions into syntactically correct SQL queries and executes them directly on the database. The system first introspects the database schema to understand tables and columns. It then uses a deterministic, prompt-driven approach to generate SQL that strictly conforms to that schema. Queries are executed in real time against the live database, and raw results are summarized into concise, business-friendly answers. As an operator rather than an advisor, Chat-with-SQL never guesses or abstracts away the database. Every natural language question is deterministically translated into SQL that exactly matches the schema. This keeps the database firmly in control and ensures users get answers they can trust.
How it Works
- Database Connection: Connect an existing SQL database using a standard connection URI.
- Schema Awareness: System reads table and column metadata to ground all queries in the actual database structure.
- Natural Language Input: Users ask questions in plain English (for example, “What were total sales last month?”).
- Intent-to-SQL Translation: The AI generates precise SQL queries aligned with the database schema.
- Query Execution: Generated SQL is run directly against the live database, ensuring up-to-date results.
- Answer Generation: Raw query results are transformed into clear, concise, contextual, human-readable responses.
