             Summary: Inconsistency with document projection
                 Key: TEIID-5551
                 URL: https://issues.jboss.org/browse/TEIID-5551
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 12.0, 11.2.1


When using the xml type for a given column the entire subtree is returned - which is universally the expected behavior.  If projection is used and another type is used, then only local node text will be considered.  If projection is disabled, all of the descendant text is considered.

Based upon our initial consistency with oracle, we should consider all of the descendant text.

for example:

Select * From XmlTable('/root' Passing xmlparse(document '<root><def><test1>10</test1><test1>20</test1></def><abc>22</abc></root>') 
Columns b varchar(40) Path 'def') xx

should return 1020.
