Verified reviews
Feedback is published only with the author’s explicit consent.
“I really liked the hands-on approach. Instead of just reading SQL theory, you actually write queries, make mistakes and learn by practising. Great for building confidence.”
A verified catalogue
From foundations to dates, joins, subqueries, CTEs and complete analyses.
Business context, approach, hints, common mistakes, solution and an extra challenge.
Eight business projects are published; the number available depends clearly on your plan.
Transparent ordering
$17 for 180 days, $34 or $51 for 365 days.
The order appears in your space. No card is entered and no automatic charge is triggered.
Payment arrangements are confirmed beforehand. After verification, the chosen level is activated by administration.
Current payment process: payment is confirmed outside the site. SQL.tn does not collect or store card data. A gateway with signed notifications will be enabled only after a provider agreement is in place.
