                 Key: DERBY-2365
                 URL: https://issues.apache.org/jira/browse/DERBY-2365
             Project: Derby
          Issue Type: Bug
          Components: Documentation
         Environment: http://db.apache.org/derby/docs/dev/ref/rrefsqlj27781.html
            Reporter: Tomohito Nakayama
            Priority: Minor


In this part, next sentence of an example exists.

For example, if the values 'z' and 'z ' are both stored in a column, you cannot 
control which one will be returned as the maximum, because a blank space has no 
value.

Because blank space is value, I think "because a blank space has no value" is 
not appropriate.

I think it should be as "because a blank space is an special value".
