TableNotFound doesn't require an account, and has no server-side backend or database. SQL practice runs entirely in your browser using WebAssembly. We don't collect or store the queries you write, your answers, or any personal information ourselves.
This site and the third-party advertising vendors it works with may use cookies and similar technologies (such as browser local storage) to operate the site, remember basic preferences, and serve and measure ads.
TableNotFound displays ads served by Google AdSense. Google and its advertising partners (collectively, third-party vendors) may use cookies to serve ads based on a visitor's prior visits to this site or other sites on the internet.
Google, as a third-party vendor, uses cookies to serve ads on this site. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet.
You may opt out of personalized advertising by visiting Google Ads Settings. You can also visit aboutads.info to opt out of third-party vendor use of cookies for personalized advertising more broadly.
We don't operate user accounts, don't process payments, and don't store your SQL queries or practice progress on any server — that state lives only in your browser's memory for the current tab.
TableNotFound is not directed at children under 13, and we don't knowingly collect personal information from children.
