Example Output
-- Optimized Query
SELECT u.id, u.name, COUNT(o.id) AS order_count
FROM users u
JOIN orders o ON u.id = o.user_id
WHERE o.created_at >= NOW() - INTERVAL '1 month'
GROUP BY u.id, u.name
ORDER BY order_count DESC;

/* Optimization Tips:
1. Index on: orders(user_id, created_at)
2. Consider materialized view for frequent reports
*/

-- Parameterized Version (Dapper/EF Core)
const query = `
  SELECT u.id, u.name, COUNT(o.id) AS order_count
  FROM users u
  JOIN orders o ON u.id = o.user_id
  WHERE o.created_at >= @startDate
  GROUP BY u.id, u.name
  ORDER BY order_count DESC
