-----------------------------------
Summary: Regression when using derived table in LEFT JOIN
Key: IGNITE-14356
URL: https://issues.apache.org/jira/browse/IGNITE-14356
Project: Ignite
Issue Type: Bug
Components: sql
Affects Versions: 2.10
Reporter: Lukas Eder
This used to work in 2.9.1 and no longer does in 2.10.0:
{code:java}
CREATE TABLE t (i int PRIMARY KEY, j int);
INSERT INTO t VALUES (1, 1);
SELECT *
FROM t AS t1
LEFT JOIN (SELECT * FROM t WHERE false) AS t2
ON t1.i = t2.i
{code}
It should result in 1 row as the LEFT JOIN should have no effect, but the
result set is empty as if t2 were inner joined.
