XMLQUERY
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The XMLQUERY()
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.xml("<doc><x>content</x></doc>"))
Translates to the following dialect specific expressions:
-- DB2 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', '<doc><x>content</x></doc>')) AS t (x)) -- ACCESS, ASE, AURORA_MYSQL, AURORA_POSTGRES, COCKROACHDB, DERBY, FIREBIRD, H2, HANA, HSQLDB, IGNITE, INFORMIX, INGRES, -- MARIADB, MEMSQL, MYSQL, REDSHIFT, SNOWFLAKE, SQLDATAWAREHOUSE, SQLITE, SQLSERVER, SYBASE, TERADATA, VERTICA /* UNSUPPORTED */
(These are currently generated with jOOQ 3.15, see #10141)
