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))) AS t (x))

-- SQLSERVER
'<doc><x>content</x></doc>'.QUERY('/doc/x')

-- ACCESS, ASE, AURORA_MYSQL, AURORA_POSTGRES, BIGQUERY, COCKROACHDB, DERBY, EXASOL, FIREBIRD, H2, HANA, HSQLDB, INFORMIX, 
-- MARIADB, MEMSQL, MYSQL, REDSHIFT, SNOWFLAKE, SQLDATAWAREHOUSE, SQLITE, SYBASE, VERTICA, YUGABYTEDB
