Rick Hillegas updated DERBY-651:
--------------------------------

    Attachment: derby-651-07-aa-dependencyView.diff

Attaching derby-651-07-aa-dependencyView.diff. This adds dependencies of views on UDTs. Regression
tests pass for me. Committed at subversion revision 889876.

Touches the following files:

M      java/engine/org/apache/derby/impl/sql/compile/QueryTreeNode.java

Adds a method for adding dependencies on UDTs.


M      java/engine/org/apache/derby/impl/sql/compile/ValueNode.java
M      java/engine/org/apache/derby/impl/sql/compile/StaticMethodCallNode.java

Wires that method into nodes which views rely on.


M      java/testing/org/apache/derbyTesting/functionTests/tests/lang/Price.java
M      java/testing/org/apache/derbyTesting/functionTests/tests/lang/UDTTest.java

Basic tests for dependencies of views on UDTs.

> Islay Symonette, in an email thread called "Storing Java Objects in a table" on October
26, 2005 requests the ability to store java objects in the database.
> Old releases of Cloudscape allow users to declare a column's type to be a Serializable
class. This feature was removed from Derby because the syntax was non-standard. However, most
of the machinery to support objects serialized to columns is still in Derby and is even used
in system tables. We need to agree on some standard syntax here and re-expose this useful
feature. Some subset of the ANSI adt syntax, cumbersome as it is, would do.
