[teiid-issues] [JBoss JIRA] (TEIID-4117) Add explicit empty handling for array values in xmltable

Add explicit empty handling for array values in xmltable -------------------------------------------------------- Key: TEIID-4117 URL: https://issues.jboss.org/browse/TEIID-4117 Project: Teiid Issue Type: Enhancement Components: Query Engine Reporter: Steven Hawkins Assignee: Steven Hawkins Currently we default to null on empty behavior, but it would be good to allow empty on empty as well: xmltable('/a' passing convert('<a></a>', xml) columns x string[] path 'b') will produce a null value, but in some cases you'd want to produce an empty array.
