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

      public String getFullDefinition()
      Returns the complete column definition including type, constraints, and other attributes.
      Returns:
      the full column definition as SQL string

    • appendAlterSQL

      public ObjectState appendAlterSQL(IStatement newCondition, SQLScript script)
      Description copied from interface: IStatement

      Parameters:
      newCondition - new object state
      script - script to collect changes
      Returns:
      object change type
