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.
<pseudo-sql>
create type myschema.useridtype as varchar(20);
</pseudo-sql>
I might have to alter the type some day and this way I'd have to just
re-define the alias. Can this be achieved by creating a new type with
CREATE TYPE? What are the input/output functions in the CREATE TYPE
definition?
Thanks.
