Agentic Multi Dialect SQL Assistant

Convert natural language to SQL queries across multiple database dialects with Order of Execution analysis - making database interaction accessible through Agentic AI.

Comment

Inspiration

The inspiration for Agentic Multi-Dialect SQL Assistant came from witnessing the daily struggles of developers, data analysts, and business users who face the complexity of SQL syntax and multi-database environments. Traditional SQL writing requires deep knowledge of different database dialects, and the learning curve is steep for non-technical users. We wanted to democratize database access by creating an intelligent assistant that could bridge the gap between natural language and SQL across multiple platforms.

What it does

Our application transforms natural language questions into executable SQL queries across five major database dialects: MySQL, PostgreSQL, Oracle, SQL Server, and Amazon Aurora. Users simply upload their database files (SQL scripts or SQLite databases) and ask questions in plain English. The system automatically analyzes the database schema, generates optimized SQL queries, provides detailed Order of Execution analysis, and displays results in interactive tables. It's like having a personal database expert who speaks multiple SQL dialects.

How we built it

We built the system using a modern tech stack centered around Agentic AI principles:

Backend Architecture:

  • Flask Framework: RESTful API for handling file uploads and query processing
  • Mistral Large LLM: Advanced language model for natural language understanding and SQL generation
  • PhiData Agentic Framework: Intelligent agent orchestration for context-aware processing
  • SQLAlchemy ORM: Database abstraction layer for multi-database support
  • SQLite Engine: Primary database for query execution and testing

Frontend Technologies:

  • Bootstrap 5.3: Modern responsive UI with Material Design principles
  • DataTables: Interactive table display with pagination and sorting
  • JavaScript/jQuery: Dynamic frontend interactions and AJAX handling
  • Custom CSS: Enhanced visual design with animations and hover effects

AI Processing Pipeline:

  1. File Processing: Parse SQL files and extract schema information
  2. Context Preparation: Combine schema data with user queries
  3. AI Generation: Use Mistral LLM to convert natural language to SQL
  4. Dialect Conversion: Generate equivalent queries for multiple database systems
  5. Execution Analysis: Provide step-by-step Order of Execution breakdown
  6. Result Display: Present formatted results with interactive features

Challenges we ran into

Technical Challenges:

  • Multi-Dialect Syntax Conversion: Converting between different SQL dialects while maintaining query accuracy was complex. Each database has unique syntax features and functions.
  • Schema Analysis: Automatically understanding database structures from uploaded files required sophisticated parsing and validation logic.
  • AI Prompt Engineering: Crafting effective prompts for the LLM to generate accurate SQL queries across different contexts was iterative and challenging.
  • Order of Execution Analysis: Creating a system to analyze and visualize SQL execution order required deep understanding of database internals.

Integration Challenges:

  • Agentic Framework Setup: Configuring the PhiData framework for optimal performance with our specific use case required extensive experimentation.
  • Real-time Processing: Balancing response times with query complexity while maintaining accuracy was a constant optimization challenge.
  • Error Handling: Implementing robust error handling for various edge cases (invalid queries, malformed files, API failures) required careful planning.
