Subject [jira] Commented: (DERBY-2365) Brushing up pages for MAX and MIN in Derby Reference Manual
Date Thu, 22 Feb 2007 16:21:05 GMT

] 

Tomohito Nakayama commented on DERBY-2365:
------------------------------------------

Reading page for MIN, 
I feel that similar description for trailing blank spaces should be in the page for MIN as
the page for MAX.

// It may be verbose to have similar description in each pages , 
// but I think that verboseness is prefered in the reference manual.

> * Description of rules for trailing blank spaces
> 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".
> * Mistaken information for LONG VARCHAR data type
> Now MAX / MIN are not allowed for LONG VARCHAR in Derby.
> However the manual mentions they are allowed.
> * mistaken maximum for MIN
> There exists next sentence in page for MIN :
> > The type's comparison rules determine the maximum value.
> Here, maximum should be minimum.
