Native id-method columns in hsqldb start with 0
-----------------------------------------------

         Key: TORQUE-32
         URL: http://issues.apache.org/jira/browse/TORQUE-32
     Project: Torque
        Type: Bug

  Components: Generator  
 Environment: Any.
    Reporter: Scott Eade
    Priority: Minor


Using hsqldb with id-method native columns creates columns defined with the \
constraint "IDENTITY". This generated an index starting with 0. As Torque regards \
objects with an primary key 0 as not initialized, this can lead to problems when \
using relationships between tables. 

To prevent this I've patched the generated string from "IDENTITY" to "GENERATED BY \
DEFAULT AS IDENTITY (STARTING WITH 0)".

This broke the created SQL for hsqldb tables since Torque preprends the String "NOT \
NULL" in front of the identity string. hsqldb does not allow this.

To change this I've patched the interface org.apache.torque.engine.platform.Platform \
and added a method "public getNullString(Column col)" since the \
PlatformHypersonicImpl needed to know if the column is a not null and if the column \
uses the native id-method. The default implementation of Platform delegates the call \
of this method to the former existing one. Only the hsqldb implementation uses more \
than the property notNull of the column.

The new method is now used getSqlString of class Column.
