XMLCONCAT

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

The XMLCONCAT() function is used to concatenate two XML fragments of arbitrary type

SELECT xmlconcat(
  xmlelement(NAME e1),
  xmlelement(NAME e2)
)

create.select(xmlconcat(
         xmlelement("e1"), 
         xmlelement("e2")))
      .fetch();

The result would look like this:

+------------+
| xmlconcat  |
+------------+
| <e1/><e2/> | 
+------------+

Dialect support

This example using jOOQ:

xmlconcat(xmlelement("e1"), xmlelement("e2"))

Translates to the following dialect specific expressions:

-- DB2, ORACLE, POSTGRES, TERADATA
xmlconcat(
  xmlelement(NAME e1),
  xmlelement(NAME e2)
)

-- SQLSERVER
(
  SELECT
    (
      SELECT
        1 tag,
        null parent,
        null [e1!1]
      FOR XML EXPLICIT, TYPE
    ),
    (
      SELECT
        1 tag,
        null parent,
        null [e2!1]
      FOR XML EXPLICIT, TYPE
    )
  FOR XML PATH (''), TYPE
)

-- ACCESS, ASE, AURORA_MYSQL, AURORA_POSTGRES, BIGQUERY, COCKROACHDB, DERBY, EXASOL, FIREBIRD, H2, HANA, HSQLDB, INFORMIX,
