      getCreationSQL in interface IStatement
      Parameters:
      script - the SQL script to append creation statements to

    • appendAlterSQL

      public ObjectState appendAlterSQL(IStatement newCondition, SQLScript script)
      Description copied from interface: IStatement
      Fill script with object changes and return change type
      Specified by:
      appendAlterSQL in interface IStatement
      Parameters:
      newCondition - new object state
      script - script to collect changes
      Returns:
      object change type
