Incorrect parsing of xml with XmlTable -------------------------------------- Key: TEIID-5541 URL: https://issues.jboss.org/browse/TEIID-5541 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 11.1 Environment: teiid-11.1.0 (from 01.09.2018) on WildFly Full 11.0.0.Final (WildFly Core 3.0.8.Final) Reporter: dalex dalex Assignee: Steven Hawkins Priority: Blocker Fix For: 11.0.3, 11.1.2, 12.0, 11.2.1 Running the query: {code:sql} Begin Declare xml xcontent = '<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <report> <data> <year xsi:type="decimal">2018</year> </data> </report> <waitSeconds xsi:type="decimal">13</waitSeconds> </root>' ; Select * From XmlTable( XmlNamespaces ('http://www.w3.org/2001/XMLSchema-instance' as xsi), '/root/report/data' PASSING xcontent Columns "year" integer, waitSeconds xml Path 'root()/root/waitSeconds', waitSecondsStr string Path 'root()/root/waitSeconds' )a ; End ;; {code} and having a look at the structure we can see that the value 13 should be returned, while the value is not picked from xml for result.
