XMLEXISTS predicate

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

The XMLEXISTS predicate can be used to check whether an XQuery or XPath expression produces a value within an XML document (see also the XMLQUERY function)

SELECT 1
WHERE xmlexists('/a/b' PASSING '<a><b/></a>')
create.selectOne()
      .where(xmlexists("/a/b").passing(XML.valueOf("<a><b/></a>")))
      .fetch();

Dialect support

This example using jOOQ:

xmlexists("/a/b").passing(xml("<a><b/></a>"))

Translates to the following dialect specific expressions:

XMLEXISTS(
  '/a/b'
  PASSING '<a><b/></a>'
)

  '/a/b'
  PASSING CAST('<a><b/></a>' AS xml)
