Yury Gerzhedovich resolved IGNITE-14356.
----------------------------------------
Resolution: Duplicate
> 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
> Assignee: Vladimir Ermakov
> Priority: Major
>
> 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.
