Dyre Tjeldvoll updated DERBY-6340:
----------------------------------
Attachment: CreateTypeAs_fs_draft_3.html
Uploading yet another preliminary draft. The issue of whether the default {{<cast to source>}}
identifiers are quoted or not is left open.
> Add support for CREATE TYPE AS <existing type> (synonym types)
> --------------------------------------------------------------

> The SQL standard (2003) chapter 11.41 <user-defined type definition> allows the
creation of synonyms or aliases for an existing type: CREATE TYPE AS <predefined type>.
By allowing this in Derby we would simplify migration from, and interoperation with, other
databases.
