Kim Haase updated DERBY-2365:
-----------------------------
Attachment: DERBY-2365-2.zip
DERBY-2365-3.diff
I think I figured it out -- I made the first sentence of MAX consistent with
the first sentences of the other aggregate functions ("the maximum of an
expression over a set of rows").
Sorry about the odd numbering: the final patch is DERBY-2365-3.diff and
DERBY-2365-2.zip. Please let me know if anything still needs fixing. I hope
this is ready to commit now.

> * 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.
