Hey,

Is it possible to create a new type as an alias to a pre-defined type? I use "USERID varchar(20)" in almost every table I have I'd like to make an alias for that type eg.


CREATE DOMAIN username_string AS varchar(20);

Test it with your client applications though, make sure they cope. Some don't cope well with user-defined types.


Splendid, thank you all :) I'm quite sure loosely typed PHP can cope with my user-defined types ;)

But now I need a better modeling tool because Azzurri Clay 1.1 (Eclipse plug-in) doesn't let me define new types... Any suggestions? SQL DDL generation is the only demand I really have.
