Wrong result (empty or NULL) with an view and a single disjunction for join criteria ------------------------------------------------------------------------------------ Key: TEIID-4262 URL: https://issues.jboss.org/browse/TEIID-4262 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.0 Reporter: Salvatore R Assignee: Steven Hawkins Priority: Blocker Fix For: 9.0, 8.12.5, 8.7.7.6_2, 8.13.6 The following query returns an empty result instead of 1: {code:sql} SELECT alias3.a1 FROM (select 1 as a) as alias2 INNER JOIN (SELECT t2.a AS a1, t1.a FROM (SELECT 1 AS a) AS t1 INNER JOIN (select 1 as a) as t2 ON t1.a = t2.a) AS alias3 ON ((alias3.a = alias2.a) OR (alias3.a > alias2.a)) {code} when updating the parent join on removing the alias3 view layer, the OR condition is being converted to AND - which can never be true.
