Knut Anders Hatlen commented on DERBY-4394:
-------------------------------------------
In the syntax description, it looks like some square brackets have been
misplaced so that the entire list of column names has been made optional. Using
{ and } for grouping may also make the syntax easier to read. I suggest
something like this:
GROUP BY
{ column-Name [ , column-Name ]* } |
{ ROLLUP ( column-Name [ , column-Name ]* ) }
The sentence starting with "Using the ROLLUP syntax" lacks a full stop. Perhaps
it's better to say "ROLLUP keyword" instead of "ROLLUP syntax" too?
The existing examples use upper case SQL statements. For consistency, we may
want to use upper case in the new example too.
> Add documentation for ROLLUP functionality in GROUP BY clause
