The FROM clause is ANSI SQL:2011-compliant with extensions.

A FROM clause is mandatory for SELECT statements in the ANSI SQL:2011 standard. The optional FROM clause in Teradata SQL is a Teradata extension.

The ANSI SQL:2011 standard also requires that all of the columns referenced in an outer query be in tables that are specified in the FROM clause, but Teradata SQL does not.
