[ https://issues.jboss.org/browse/TEIID-4262?page=com.atlassian.jira.plugin... ] Steven Hawkins updated TEIID-4262: ---------------------------------- Description: 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. was: The following query returns an empty result instead of 1: {code:sql} WITH alias as (SELECT 1 as a), alias2 as (select t2.a as a1, t1.a from alias t1 join (SELECT 1 as a) t2 on t1.a=t2.a), alias3 as (select t2.a as a1, t1.a from alias t1 join alias2 t2 on t1.a=t2.a) SELECT alias3.a1 FROM alias2 join alias3 on alias3.a=alias2.a or alias3.a>alias2.a {code} This similar query (using LEFT instead of INNER join) returns NULL instead of 1: {code:sql} WITH alias as (SELECT 1 as a), alias2 as (select t2.a as a1, t1.a from alias t1 join (SELECT 1 as a) t2 on t1.a=t2.a), alias3 as (select t2.a as a1, t1.a from alias t1 join alias2 t2 on t1.a=t2.a) SELECT alias3.a1 FROM alias2 left join alias3 on alias3.a=alias2.a or alias3.a>alias2.a {code} Fix Version/s: 8.12.5 8.13.6 Summary: Wrong result (empty or NULL) with an view and a single disjunction for join criteria (was: Wrong result (empty or NULL) running a CTE) Affects Version/s: 7.0 (was: 9.0) -- This message was sent by Atlassian JIRA (v6.4.11#64026)
