Subject [jira] Commented: (DERBY-4896) Would like more detail on what PlanExporter means by the term "advanced"
Date Wed, 10 Nov 2010 13:52:13 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4896?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12930595#action_12930595

Rick Hillegas commented on DERBY-4896:
--------------------------------------

Thanks for that quick response, Bryan. If "advanced" just means "alternate", does that mean
that there is no longer any need for the -adv switch? The documentation in the Tools guide
(http://db.apache.org/derby/docs/dev/tools/tools-single.html#ctoolsusingplanexp) indicates
that you can you an alternate style sheet by specifying these switches:

-xsl $styleSheet -html $htmlOutput

It goes on to say that you can generate advanced output by throwing an additional switch:

-adv -xsl $styleSheet -xml $xmlOutput

I notice that the following combination of switches gives me a usage diagnostic:

-xsl $styleSheet -xml $xmlOutput

So "advanced" may have something to do with whether you are generating html or xml output.

> 1) The PlanExporter documentation uses the term "advanced style sheets". It would good
to say something more about what we mean by "advanced". Does "advanced" just mean that the
style sheet can contain javascript? If so, it would be good to say so.
> 2) Derby supplies two "advanced" style sheets. I think it is worth saying something about
what these style sheets do for you. Perhaps something as simple as this: "Derby supplies two
advanced style sheets which use javascript to expand and collapse the details of query plan
nodes."
