    [ https://issues.jboss.org/browse/TEIID-2336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12787066#comment-12787066 ] 

Steven Hawkins commented on TEIID-2336:
---------------------------------------

After some more thought it looks like the simplest route to supporting this is to always just rewrite array_table as the individual array_get calls.  There is more reflective overhead, but that is usually much less than the overhead of processing the implied join.
