Thanks for picking this up. If you look in the existing Derby code you
will find some runtime support already, look at this class.

org.apache.derby.impl.sql.execute.AlterTableConstantAction

Feel free to use that code or write new code, using the above code may
allow a quicker project, as it comes down to enhancing the parser to use
that code at runtime, like the current ALTER TABLE command.

And of course tests :-)

Dan.
