Enum StandardVersion 

pub enum StandardVersion {
    Sql1999,
    Sql2003,
    Sql2008,
    Sql2011,
    Sql2016,
}

A frozen SQL-standard edition, used to anchor feature availability to a release without enumerating features (ZetaSQL’s LanguageVersion checkpoints).

These are the feature-ID-era editions: the Ennn/Fnnn/Tnnn feature taxonomy was introduced in SQL:1999, so it is the earliest anchor. Declaration order is chronological, so Ord reads as “released no later than”.

Variants

Sql1999

SQL:1999 — first edition with the named-feature taxonomy.

Sql2003

SQL:2003 — adds windowed table functions (OLAP), MERGE, sequences.

Sql2008

SQL:2008.

Sql2011

SQL:2011.

Sql2016

SQL:2016 — the edition “generic”/ANSI is anchored on.
