ROOT directive
Applies to ❌ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The ROOT directive allows for wrapping the XML document fragment in a root element.
Consider the following query
SELECT id, title
FROM book
ORDER BY id
FOR XML RAW, ROOT ('result')
create.select(BOOK.ID, BOOK.TITLE)
.from(BOOK)
.orderBy(BOOK.ID)
.forXML().raw().root("result")
.fetch();
This query produces a document like this:
<result> <row ID="1" TITLE="1984"/> <row ID="2" TITLE="Animal Farm"/> <row ID="3" TITLE="O Alquimista"/> <row ID="4" TITLE="Brida"/> </result>
Dialect support
This example using jOOQ:
select(BOOK.ID).from(BOOK).orderBy(BOOK.ID).forXML().raw().root("result")
Translates to the following dialect specific expressions:
DB2, Oracle, Postgres
SELECT xmlelement(
NAME result,
xmlagg(xmlelement(
NAME row,
xmlattributes(t.ID AS ID)
))
)
FROM (
SELECT BOOK.ID
FROM BOOK
ORDER BY BOOK.ID
) t
SQLServer
SELECT (
SELECT BOOK.ID
FROM BOOK
ORDER BY BOOK.ID
FOR XML RAW, ROOT ('result')
)
