not null is not enforced for non-virtual system procedures ---------------------------------------------------------- Key: TEIID-5309 URL: https://issues.jboss.org/browse/TEIID-5309 Project: Teiid Issue Type: Bug Components: Query Engine Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 10.3 Just like with foreign physical procedures we assume that the non-null constraint is enforced at the data manager layer - however that logic doesn't exist for non-virtual system procedures. This leads to inconsistent behavior when using null literals and expressions that eventually evaluate to null.
