In terms of SQL conformance, the official name of the SQL standard is ISO/IEC 9075 "Database Language SQL", with the latest version being ISO/IEC 9075:2003, also known as SQL:2003. It supersedes all previous versions, which includes SQL:1999 and SQL-92; any claims of conformance to earlier versions don't carry any official weight.
Since SQL:1999, the SQL standard lists a large set of individual features instead of the three levels (Entry, Intermediate and Full) declared in SQL-92. The mandatory features, dubbed the "Core" subset, must be supplied by every SQL implementation as part of its conformance claim. All remaining features are entirely optional.
We've compiled a complete list of all SQL:2003 features that Gladius DB supports. Each feature comes with an identifier and name, with hyphens used to denote subfeatures. In cases where a subfeature isn't supported, the main feature is only partly supported, and we've included comments when helpful.
