> Key: IGNITE-14354
> URL: https://issues.apache.org/jira/browse/IGNITE-14354
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Affects Versions: 2.10
> Reporter: Lukas Eder
> Assignee: Vladimir Ermakov
> Priority: Major
> Fix For: 2.13
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> This worked as expected in 2.9.1:
>
> {code:java}
> CREATE TABLE t (i int PRIMARY KEY, j int);
> SELECT (EXISTS (SELECT 1 FROM t WHERE t.i = 1));
> {code}
> In version 2.10, I'm getting:
> {code:java}
> SQL Error [1001] [42000]: Failed to parse query. Column "EXISTS1" not found;
> SQL statement:
> SELECT
> (EXISTS1)
> FROM SYSTEM_RANGE(1, 1) __Z0
> LEFT OUTER JOIN PUBLIC.T __Z1
> ON __Z1.I = 1 [42122-197]{code}
> The workaround is to project an asterisk:
> {code:java}
> SELECT (EXISTS (SELECT * FROM t WHERE t.i = 1));{code}
