Dag H. Wanvik commented on DERBY-6109:
--------------------------------------
Trying to grok that rationale for this, what would be the difference between a
"wrapper view" and this new mechanism? And how would it facilitate projection
pushing?
> Allow CREATE SYNONYM for table function invocations.

> SYNONYMs are a non-standard extension supported by many databases. See
> DERBY-335. Right now SYNONYMs are only allowed for tables and views. It would
> be useful (and should be easy) to extend this feature to support SYNONYMs for
> table function invocations. E.g.:
> CREATE SYNONYM LT0 for TABLE( LT0() )
> CREATE SYNONYM LT0_P for TABLE( LT0('with_provenance') )
> See the discussion of this topic on this email thread:
