XMLQUERY
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The XMLQUERY() function allows for extracting content from an XML document using XQuery or XPath
SELECT xmlquery('/doc/x'
PASSING xmlparse(DOCUMENT '<doc><x>content</x></doc>')
RETURNING CONTENT
)
FROM dual
create.select(xmlquery("/doc/x")
.passing(
XML.xml("<doc><x>content</x></doc>")
))
.fetch();
The result would look like this:
+----------+ | xmlquery | +----------+ | content | +----------+
Dialect support
This example using jOOQ:
xmlquery("/doc/x").passing(xml("<doc><x>content</x></doc>"))
Translates to the following dialect specific expressions:
-- DB2, TERADATA
xmlquery(
'/doc/x'
PASSING '<doc><x>content</x></doc>'
)
-- ORACLE
xmlquery(
'/doc/x'
PASSING '<doc><x>content</x></doc>'
RETURNING CONTENT
)
-- POSTGRES
(SELECT xmlagg(x)
FROM UNNEST(xpath('/doc/x', CAST('<doc><x>content</x></doc>' AS xml))) t (x))
-- SQLSERVER
'<doc><x>content</x></doc>'.QUERY('/doc/x')
