> If you invoke a table function as a scalar function, Derby instantiates the 
> ResultSet returned by the table function and returns that ResultSet. This 
> behavior looks wrong. Derby should raise an error if you invoke a table 
> function as a scalar function. Here is an example of the problem:
> ij> values ( badVTI( 'foo' ) );
