Rick Hillegas commented on DERBY-716:
-------------------------------------

Attaching derby-716-07-dblook-aa.diff. This patch changes the type name 
returned by the RowMultiSetImpl class. The type name has been changed so that 
dblook will emit re-playable DDL for Table Functions. The type name has been 
changed from 'ROW( col1 type1, ... ) MULTISET' to 'TABLE( "COL1" type1, ... )'. 
Touches the following files:

M      java/engine/org/apache/derby/catalog/types/RowMultiSetImpl.java

Changes the type name.

M      
java/testing/org/apache/derbyTesting/functionTests/tests/lang/TableFunctionTest.java

Adjusts this test to account for the new type name.

> Cloudscape used to expose Virtual Table Interfaces, by which any class which 
> implemented ResultSet could be included in a query's FROM list. Derby still 
> exposes a number of these VTIs as diagnostic tools. However, Derby now 
> prevents customers from declaring their own VTIs. The parser raises an error 
> if a VTI's package isn't one of the Derby diagnostic packages.
> This is a very powerful feature which customers can use to solve many 
> problems. We should discuss the reasons that it was disabled and come up with 
> a plan for putting this power back into our customers' hands.
