RE: DDS ALIAS keyword

Buck,

Sorry, I did misunderstand what you wanted.

The only way (in SQL) that I know of to give a column two names is on the
CREATE TABLE statement. Have you considered creating views for them? It
would be trivial to create a tool that generates the necessary SQL statement
for each table.
