Subject [jira] Commented: (DERBY-2365) Example of MAX in Derby Reference Manual is not explained appropriately
Date Wed, 21 Feb 2007 15:14:05 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2365?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12474726
] 

Bryan Pendleton commented on DERBY-2365:
----------------------------------------

Perhaps:

   "because one or more trailing blank spaces at the end of a character string do not distinguish
it from the same string without the trailing blanks".

Does a wording like that make the meaning any clearer?

> 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".
