Subject [jira] Commented: (DERBY-4394) Add documentation for ROLLUP functionality in GROUP BY clause
Date Thu, 15 Oct 2009 11:00:31 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4394?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12766008#action_12766008

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:

  { 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.
