Indeed. There's definitely nothing standard about sql (intentionally lower cased for fun) what with every DB out there adopting their own set of features. Even the core syntax of sql can vary significantly eg joining tables in Oracle's PL/SQL vs ANSI SQL (eg MySQL). When something as basic to the concept of sql as table joins can very so significantly, you have to question what the GP was smoking to assume the "S" in SQL stood for "Standard" :P

As an aside, I also love the fact he presumed the author of usql - someone who has been reverse engineering undocumented drivers to bring support to Go(lang) - was unaware of what the name of his own tool and the language it exposes stood for, is just laughable.

Acronyms should also be capitalized.

I think they're saying "SEQUEL", which is the widely accepted/recognized pronounced mononym for "SQL".
