Sql/xml - powerful tool for complex reports

Question

I just want to share euphoria...
HTMLDB itself provides powerful ways how to control the design of the page - various types of regions, page types, templates...
Nevertheless sometimes you need even more precise control over the content and format of the displayed page. The combination of SQL/XML and HTMLDB solves it in very elegant way.
- create page with common SQL report region.
- prepare the SELECT gathering the data to be displayed
- prepare another SELECT using SQL/XML functions adding HTML formating tags upon the first select.
Example:
select
XMLTYPE.getStringVal(
XMLElement("table",
XMLAttributes('5' as cellpadding),
XMLConcat(
XMLElement("tr",
XMLElement("td",
XMLAttributes('left' as align, 'top' as valign),
XMLElement("a",
XMLAttributes(provider_url as href),
XMLElement("img",XMLAttributes(provider_icon as src, provider_name as alt, provider_name as title))
XMLElement("td",
XMLAttributes('left' as align, 'top' as valign, '150' as width),
XMLElement("a",
XMLAttributes(event_url as href),
XMLElement("div",XMLAttributes('font-weight:bold; font-style:normal; font-size:10px; ' as style), event_name_part2)
XMLElement("div",XMLAttributes('font-weight:normal; font-style:normal; font-size:10px; ' as style), event_name_part1)
XMLElement("td",
XMLAttributes('right' as align, 'top' as valign),
XMLElement("div",
XMLElement("a",
XMLAttributes( edit_url as href),
XMLElement("img",
XMLAttributes( '#IMAGE_PREFIX#ed-item.gif' as src, '14' as width, '14' as height, 'Editovat článek/pořad' as alt, 'Editovat článek/pořad' as title)
XMLElement("div",
XMLElement("a",
XMLAttributes( delete_url as href),
XMLElement("img",
XMLAttributes( '#IMAGE_PREFIX#wastebasket.gif' as src, '16' as width, '16' as height, 'Smazat článek/pořad' as alt, 'Smazat článek/pořad' as title)
) as event_description
from (select
case
when EVENT_PROVIDER_TYPE='Magazine' then set_1 || ' ' || set_2 || ' ' || set_3 || ' ' || set_4
when EVENT_PROVIDER_TYPE='Radio' then set_1 || ' ' || set_2 || ' ' || set_3 || ' ' || set_4
when EVENT_PROVIDER_TYPE='Author' then set_2
end as event_name_part1,
case
when EVENT_PROVIDER_TYPE='Magazine' then set_5 || ' ' || set_6
when EVENT_PROVIDER_TYPE='Radio' then set_5 || ' ' || set_6
when EVENT_PROVIDER_TYPE='Author' then set_1
end as event_name_part2,
events.url as event_url,
my_events.issue_date,
providers.icon_path as provider_icon,
providers.provider_name,
case
when substr(upper(providers.www_address),1,7)<>'HTTP://'
then 'http://' || providers.www_address
else providers.www_address
end as provider_url,
'f?p=' || v('APP_ID') || ':2:' || v('SESSION') || '::NO:16:P2_EVENT_ID,P2_EVENT_NAME:' || events.event_id || ',' || events.event_name as delete_url,
'f?p=' || v('APP_ID') || ':35:' || v('SESSION') || '::NO:35:P35_SELECTED_EVENT_ID,P35_SELECTED_EVENT_NAME:' || events.event_id || ',' || events.event_name as edit_url
from my_events
join events on my_events.event_id=events.event_id
join providers on EVENTS.PROVIDER_ID= PROVIDERS.PROVIDER_ID
where my_events.user_id=:IAL_USER_ID
order by my_events.issue_date desc)
P.S. It's cool to use XMLAGG function in combination with GROUP BY clause - it enables you to easily display list of strings as a single filed on the formular....

You will be able to use our XSL Processor to format into HTML or
CSV once it is released next month. Adobe is sponsoring a
context for a PDF engine for XML.
