[teiid-issues] [JBoss JIRA] (TEIID-2381) Expanded source hint support

[Steven Hawkins (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-2381?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12780572#comment-12780572 ] 

Steven Hawkins commented on TEIID-2381:
---------------------------------------

#1 is straight-forward.
#2 seems to imply a couple of things.  First is that user source hints would no longer have the ability to affect source queries under a stored / for each row procedure.  I'm not sure how often that application would be used (or is useful) in practice. 2.a. is also not really feasible unless we add some additional logic to positionally track subqueries and or move some of the hint application logic to the rewrite phase (as post rewrite the query structure may have changed altering how subqueries or even views could be referenced).

> We currently look at the source hint in only the root user query (not in subqueries nor the with clause) and only consider it in a very narrow set of circumstances when it's used in a view.
