Try it on a real database

A demo store: 2,000 customers, 6,000 orders, 3,000 reviews, 2,500 support tickets, 600 staff. Read-only. Write SQL with jev() in it, press run, and watch the bill.

SELECT id, subject, priority
FROM tickets
WHERE status = 'open' AND priority IN ('high', 'urgent')
  AND jev((subject, body), 'the customer sounds angry or is threatening to leave')
ORDER BY created_at DESC
LIMIT 15;

Read-only demo data. Every row that survives the SQL filters is judged; this node caps a query at 300 rows.
