Steven Hawkins resolved TEIID-2669.
-----------------------------------
Resolution: Done
Our consideration of three-value null handling for the left expression was trumping the
proper handling of empty in/quantified comparison. Corrected the rewriter and evaluator.
In subquery with no values returns wrong result
-----------------------------------------------
Key: TEIID-2669
URL: https://issues.jboss.org/browse/TEIID-2669
Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 7.4
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Priority: Critical
Fix For: 8.6
If an in subquery is entered such that no rows will be returned and it is not pushed
down, then the rewriter will incorrectly convert the in predicate to an is not null check.
