It's a fully fledged, horrible language. Anything beyond basic queries is unreadable, ESPECIALLY when it's done in plain strings in another language. There's not even a way to not have to repeat values EVERY SINGLE TIME (think variables or constants in every other language).
Oh, but what about <feature>? Well, is that SQL, or a frankensteined version of SQL, aka a "dialect"?
SQL is the JavaScript of databases, and we'll be better for it once we admit this.
