[teiid-issues] [JBoss JIRA] (TEIID-4347) ORDER BY fails with a subselect containing UNION ALL

ORDER BY fails with a subselect containing UNION ALL ---------------------------------------------------- Key: TEIID-4347 URL: https://issues.jboss.org/browse/TEIID-4347 Project: Teiid Issue Type: Bug Reporter: Salvatore R Assignee: Steven Hawkins Running the following query: {code:sql} select s from ( select 1 as o, 'a' as s union all select 0 as o, 'b' as s )f order by f.o {code} throws java.lang.ArrayIndexOutOfBoundsException. It looks like the bug occurs only if the element used in the order by clause is not projected in the SELECT. In fact, this query works correctly: {code:sql} select s from ( select 1 as o, 'a' as s union all select 0 as o, 'b' as s )f order by f.s {code}
