             Summary: xsi:nil is not honored by xmltable
                 Key: TEIID-2580
                 URL: https://issues.jboss.org/browse/TEIID-2580
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 7.7
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 8.4.1, 8.5


If an element is returnable by xmltable, but marked as nil more than likely an exception will be produced when attempting to convert the empty string value to a result.

For example:

{code}
select * from xmltable('/a/b' passing convert('<a xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"><b xsi:nil=\"true\" xsi:type=\"xs:int\"/><b>1</b></a>', xml) columns val integer path '.') as x
{code}

will error converting the first b element to an integer.
