What is sql query editor free?

A sql query editor free is a tool that lets you write and run SQL without cost, typically offering a text editor, schema browser, and output grid. These tools are great for quick analysis, but they often lack guardrails like dialect-aware linting, query explanations, and prompts that translate business questions into correct, performant SQL. This gap is where AI2sql steps in. AI2sql acts as your AI assistant on top of any free editor or database UI: it turns plain language into precise, dialect-specific queries, explains each clause, and suggests safer or faster alternatives. You can paste the generated SQL into your favorite free editor or run it directly where you work.

Real sql query editor free Examples (copy-paste)

Example 1 (MySQL): sql query editor free request to find the top 5 products by revenue in the last 30 days.

SELECT p.name AS product_name, SUM(oi.quantity * oi.unit_price) AS revenue FROM orders o JOIN order_items oi ON oi.order_id = o.id JOIN products p ON p.id = oi.product_id WHERE o.status = 'paid' AND o.order_date >= CURDATE() - INTERVAL 30 DAY GROUP BY p.name ORDER BY revenue DESC LIMIT 5;

Example 2 (PostgreSQL): Marketing wants monthly new users this year for a dashboard.

SELECT DATE_TRUNC('month', u.created_at) AS month, COUNT(*) AS new_users FROM users u WHERE DATE_PART('year', u.created_at) = DATE_PART('year', CURRENT_DATE) GROUP BY month ORDER BY month;

Example 3 (BigQuery): Product analytics needs active users in the last 7 days by country.

SELECT country, COUNT(DISTINCT user_id) AS active_users FROM dataset.events WHERE event_date >= DATE_SUB(CURRENT_DATE(), INTERVAL 7 DAY) GROUP BY country ORDER BY active_users DESC;

Example 4 (PostgreSQL): CRM team wants to flag VIP customers based on lifetime spend.

UPDATE customers SET is_vip = TRUE WHERE lifetime_spend > 10000 AND (is_vip IS DISTINCT FROM TRUE);

Example 5 (MySQL): Data quality check to find duplicate user emails.

SELECT email, COUNT(*) AS cnt FROM users WHERE email IS NOT NULL AND email <> '' GROUP BY email HAVING COUNT(*) > 1 ORDER BY cnt DESC;

Each snippet can be generated by describing the intent in plain language to AI2sql, then selecting your engine. Copy the SQL into your sql query editor free to run and iterate quickly.
