>             Project: Ignite
>          Issue Type: Bug
>          Components: sql
>    Affects Versions: 2.10
>            Reporter: Lukas Eder

>            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.
