          - 
            buffer-sequence-number
          
 
          - An integer that represents the sequence number of the desired buffer.
Note: Sequence numbers for buffers of a query start
at one, where one represents the top level and subsequent numbers
represent lower levels of join, if any.
 
        
      
      
        
          - 
            buffer-name
          
 
          - A CHARACTER expression that evaluates to the name of a buffer in the query or
            ProDataSet object.
 
        
      
      If the buffer cannot be found, this attribute returns the Unknown value
        (?).
