Steven Hawkins resolved TEIID-5529.
-----------------------------------
Resolution: Done
Updated the criteria validation logic to selectively use different checks of whether an
expression will evaluate to a constant depending upon whether it's in the context of
just a query or the inclusion of a subquery for pushdown.
Non-pushed subquery may have evaluatable predicates not pushed
--------------------------------------------------------------
Key: TEIID-5529
URL:
https://issues.jboss.org/browse/TEIID-5529
Project: Teiid
Issue Type: Bug
Components: Query Engine
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Priority: Major
Fix For: 12.0
For example, a source that does not support lower nor correlated subqueries and a query
like:
SELECT array_agg((select intkey from bqt1.smallb where stringkey = lower(a.stringkey)))
from bqt1.smalla a
will not push stringkey = lower(a.stringkey) to the n-many subquery, even though it can
be pre-evaluated with the correlated value.
