Rick Hillegas updated DERBY-716:
--------------------------------

    Attachment: derby-716-03-DatabaseMetaData-aa.diff

Committed derby-03-DatabaseMetaData-aa.diff at subversion revision 564800. This removes the
summary row 0 (describing the whole ROW MULTISET) from the ResultSet returned by DatabaseMetaData.getFunctionColumns()
as Lance said is required. Touches the following files:

M      java/engine/org/apache/derby/catalog/GetProcedureColumns.java
M      java/testing/org/apache/derbyTesting/functionTests/tests/lang/TableFunctionTest.java

> 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.
