Real-World Examples: Your AI Assistant in Action

Let's see how an AI assistant like AI2sql can handle common tasks.

1. Generating a Complex Query

Your Prompt: "Calculate the 7-day moving average of daily revenue for the last month."

-- Generated by your AI Assistant (for PostgreSQL)
WITH daily_revenue AS (
    SELECT
        DATE_TRUNC('day', order_date)::DATE AS day,
        SUM(order_total) AS revenue
    FROM orders
    WHERE order_date >= NOW() - INTERVAL '30 days'
    GROUP BY 1
)
SELECT
    day,
    revenue,
    AVG(revenue) OVER (ORDER BY day ROWS BETWEEN 6 PRECEDING AND CURRENT ROW) AS moving_avg_7d
FROM daily_revenue
ORDER BY day;

2. Optimizing a Slow Query

Your Input (Slow Query):

-- Find customers who have spent more than the average total spend
SELECT * FROM customers WHERE customer_id IN (
  SELECT customer_id FROM orders GROUP BY customer_id HAVING SUM(order_total) > (SELECT AVG(total) FROM (SELECT SUM(order_total) as total FROM orders GROUP BY customer_id) as avg_query)
);

AI Assistant's Optimized Version (using CTEs):

WITH customer_spend AS (
    SELECT
        customer_id,
        SUM(order_total) AS total_spend
    FROM orders
    GROUP BY customer_id
),
avg_spend AS (
    SELECT AVG(total_spend) AS avg_total_spend FROM customer_spend
)
SELECT c.*
FROM customers c
JOIN customer_spend cs ON c.customer_id = cs.customer_id
WHERE cs.total_spend > (SELECT avg_total_spend FROM avg_spend);
