XMLELEMENT

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

The XMLELEMENT() function is used to create XML elements, possibly with attributes (see XMLATTRIBUTES())

SELECT 
  xmlelement(NAME e1) AS e1,
  xmlelement(NAME e2, xmlattributes('1' AS a)) AS e2,
  xmlelement(NAME e3, 'text-content') AS e3,
  xmlelement(NAME e4, xmlelement(NAME nested)) AS e4
 
create.select(
         xmlelement("e1").as("e1"), 
         xmlelement("e2", xmlattributes(val("1").as("a"))).as("e2"),
         xmlelement("e3", val("text-content")).as("e3"),
         xmlelement("e4", xmlelement("nested")).as("e4"))
      .fetch();

The result would look like this:

+-------+-------------+-----------------------+--------------------+
| e1    | e2          | e3                    | e4                 |
+-------+-------------+-----------------------+--------------------+
| <e1/> | <e2 a="1"/> | <e3>text-content</e3> | <e4><nested/></e4> |
+-------+-------------+-----------------------+--------------------+

This example using jOOQ:

xmlelement("e1", val("text-content"))

Translates to the following dialect specific expressions:

-- DB2, ORACLE, POSTGRES
xmlelement(NAME e1, 'text-content')

-- ACCESS, ASE, AURORA_MYSQL, AURORA_POSTGRES, COCKROACHDB, DERBY, FIREBIRD, H2, HANA, HSQLDB, INFORMIX, INGRES, MARIADB, 
-- MEMSQL, MYSQL, REDSHIFT, SQLDATAWAREHOUSE, SQLITE, SQLSERVER, SYBASE, TERADATA, VERTICA
