If you're a founder or PM, you've probably been in this situation: you need a number from your database, but your engineer is busy. So you wait. Hours. Sometimes days.

Here are 5 queries you'll need constantly — and why you shouldn't have to write them yourself:

1. "How many users signed up this month?"

SELECT COUNT(*) FROM users WHERE created_at >= DATE_TRUNC('month', NOW());

2. "What's our revenue by plan?"

SELECT plan_name, SUM(amount) FROM payments GROUP BY plan_name ORDER BY SUM(amount) DESC;

3. "Who are our most active users?"

SELECT user_id, COUNT(*) as actions FROM events GROUP BY user_id ORDER BY actions DESC LIMIT 10;

4. "How many users churned last month?"

SELECT COUNT(*) FROM subscriptions WHERE canceled_at BETWEEN DATE_TRUNC('month', NOW() - INTERVAL '1 month') AND DATE_TRUNC('month', NOW());

5. "What's our conversion rate from trial to paid?"

SELECT ROUND(COUNT(CASE WHEN status = 'active' THEN 1 END)::numeric / COUNT(*) * 100, 2) as conversion_rate FROM subscriptions WHERE trial_end IS NOT NULL;

The problem isn't that these queries are hard. It's that you shouldn't need to learn SQL just to understand your own business.

That's why I built AskSQL — paste your schema, ask in English, get the query. No SQL knowledge needed.
