LLM SQL Generator: AI-Powered Natural Language to SQL Tool

Write Your First SQL Query in 10 Seconds—Free

SQL query writing is often a complex process requiring deep knowledge of database schemas, syntax, and relationships. AI2SQL leverages Large Language Models (LLMs) to streamline SQL generation, transforming natural language inputs into precise, production-ready SQL queries.

With AI2SQL, you can focus on data insights while the AI handles query complexity.

How AI2SQL Works

Step 1: Provide a Natural Language Prompt

Example: “List all active customers who haven’t purchased in the last three months.”

Step 2: Get a Custom SQL Query

SELECT customer_id, customer_name, email, last_purchase_date FROM customers WHERE is_active = 1 AND last_purchase_date < CURRENT_DATE - INTERVAL ‘3 months’ ORDER BY last_purchase_date DESC

Step 3: Refine and Execute

Use the query as-is or refine further for specific needs.

Real-World Use Cases

1. Data Analytics

Prompt: “Show sales trends by region for the last quarter.”

SELECT region, SUM(total_sales) as total_revenue FROM sales WHERE sale_date >= DATE_TRUNC(‘quarter’, CURRENT_DATE - INTERVAL ‘1 quarter’) GROUP BY region ORDER BY total_revenue DESC

2. Business Intelligence Dashboards

Prompt: “Create a report of monthly revenue growth compared to last year.”

WITH revenue_data AS ( SELECT DATE_TRUNC(‘month’, sale_date) as month, SUM(amount) as revenue FROM sales GROUP BY DATE_TRUNC(‘month’, sale_date) ) SELECT month, revenue, LAG(revenue, 12) OVER (ORDER BY month) as last_year_revenue, (revenue - LAG(revenue, 12) OVER (ORDER BY month)) as growth FROM

3. Database Optimization

Prompt: “Identify and delete duplicate rows in the users table.”

DELETE FROM users WHERE id NOT IN ( SELECT MIN(id) FROM users GROUP BY email )
