Steven Hawkins resolved TEIID-536.
----------------------------------
Fix Version/s: 7.1.1
(was: 8.x)
Resolution: Done
Added better detection and evaluation of non-pushdown sub-queries even in update/stored
proc scenarios (this was a side effect of TEIID-1322). It would be possible (although not
as likely of a situation) to add handling for exists or to rewrite some of quantified
comparisons as scalars. This will be done if needed.
Evaluate uncorrleated subqueries prior to pushdown for all command
types.
--------------------------------------------------------------------------
Key: TEIID-536
URL: https://jira.jboss.org/browse/TEIID-536
Project: Teiid
Issue Type: Feature Request
Components: Query Engine
Affects Versions: 6.0.0
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 7.1.1
Criteria and expressions containing uncorrelated subqueries that cannot be pushed down
should be evaluated at the access node. Currently they require the introduction of a
separate select node or will simply fail for insert/update/delete.
