Oh, you've got me. Now I see the contradiction between the
articles. It's really dangerous to write anything about the
standards without having the holy books really near.

In this case I must guess, that UNION DISTINCT is in SQL:99
but not in SQL:92. Anyway, it's really not the most important
feature, I concede.

Very reasonable. But If I ask for feature that enable me to
use standard DDL with Firebird (e.g. nameable constraints
for domains), would this be considered a valid motive?
