Terms of Use

These terms cover the use of sqlpress.com. Reading the site means accepting them. They are short because the site is simple: it publishes articles, it asks nothing of you, and it takes nothing from you.

What this site is

SQLPress publishes editorial articles about database systems — query planning, storage internals, concurrency and operations. It is a publication, not a service and not a consultancy.

Reading an article creates no client relationship, no support obligation, and no professional advice relationship. Nothing here is legal, financial or compliance advice.

Accuracy, and its limits

Articles state the versions, hardware, dataset and configuration behind any number they report, so results can be checked rather than trusted. That standard is the point of the site, and it is also the boundary of what is promised.

• A measurement is valid for the environment declared in the article. Your planner, your data distribution and your configuration will differ, sometimes enough to reverse the conclusion
• Database systems change. A behavior documented against one version may not hold in the next
• Errors happen. Corrections are published in place with the date and the evidence that changed the conclusion, not removed quietly

SQL and shell commands published here can destroy data or take a system offline. DROP, ALTER, VACUUM FULL, index rebuilds, configuration changes and anything holding a lock all belong on a copy of your data first. Run nothing against production that you have not understood and tested elsewhere. You are responsible for what you run on your own systems.

The site is provided as is, without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose and non-infringement. To the fullest extent permitted by law, SQLPress is not liable for any loss of data, profit, revenue or business, or for any indirect or consequential damage, arising from use of the site or reliance on anything published on it.

Intellectual property

Articles and images

Article text, illustrations and generated cover images are © SQLPress, all rights reserved. You may:

• link to any page freely
• quote a reasonable extract — a few sentences, a table row, a plan fragment — with attribution to SQLPress and a link to the source article

You may not republish whole articles, translate and repost them, or present the content as your own, whether or not the byline is kept.

Code samples

Code samples, SQL statements, configuration snippets and query plans printed in articles are free to use, modify and ship in your own projects, commercial or not, with no attribution required and no warranty attached. They are teaching material; the point is for them to be used.

Trademarks

PostgreSQL, MySQL, SQL Server, Oracle, SQLite and other product names belong to their respective owners. They are used here to identify the systems under discussion. SQLPress is not affiliated with, endorsed by or sponsored by any of them.

Automated access and AI crawlers

Crawling is welcome within the limits published in /robots.txt. Search engines and answer engines — including LLM crawlers — are explicitly allowed, and machine-readable copies are provided on purpose:

• /llms.txt and /llms-full.txt
• a Markdown twin of every article at /blog/<slug>.md
• RSS and JSON Feed

Two conditions apply. Fetch at a rate that does not degrade the site for human readers, and where content is quoted or summarized in an answer, name SQLPress and link to the source article. Systems that ignore robots.txt or hammer the origin may be blocked at the edge.

Training on published articles is permitted under the same attribution expectation. Republishing the corpus as a standalone dataset or a derivative site is not.

Availability

The site is static and hosted on a CDN, but no uptime is guaranteed. Pages, URLs, feeds and endpoints may change or be withdrawn. Where a URL changes, a redirect is put in place where practical.

Links to other sites

Articles cite documentation, source code, mailing list threads and papers. Those destinations are not under SQLPress’s control, and linking to a source is not an endorsement of the site hosting it.

Changes to these terms

Revisions are published here with a new Last updated date. Continued use after a revision means accepting it. Material changes will be described rather than slipped in.
