Short answer: NO
Reference Tables are not SQL Standard, so I suspect there will not be any
improvements or enhancements in near future.

Subject: SQL reference file
I found an old thread in the archives about replicating DDS reference file
functionality.
CREATE TABLE xxxx AS (SELECT col1, col2, ... FROM ref_table)...
I have done this in the past but I was never fond of it because I felt the
code was complicated and not always clear for a couple of reasons:
a) "One-off" fields had to be defined with a CAST statement or all fields
needed to be in your reference table
b) Constraints (including primary key) had to be done as an ALTER TABLE.
Have any improvements been made around this topic? Is there any tooling
that helps with creating table definitions based on reference columns?
Thanks,
Brian
