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.
