published regularly since. Most revisions have added significant new features to
the language, and as a result no database claims to support the full breadth of
features. This parser currently supports most of the SQL-92 syntax, plus some
syntax from newer versions that have been explicitly requested, plus some MSSQL-
and PostgreSQL-specific syntax. Whenever possible, the [online SQL:2011
grammar][sql-2011-grammar] is used to guide what syntax to accept. (We will
happily accept changes that conform to the SQL:2016 syntax as well, but that
edition's grammar is not yet available online.)

Unfortunately, stating anything more specific about compliance is difficult.
There is no publicly available test suite that can assess compliance

* the relevant bits of the [SQL grammar][sql-2011-grammar], if the syntax is
part of SQL:2011; and
