[jira] [Commented] (IGNITE-12229) Column not found when using CASE
named column from result
[ https://issues.apache.org/jira/browse/IGNITE-12229?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16937031#comment-16937031 ]
Ilya Kasnacheev commented on IGNITE-12229:
------------------------------------------
I think I also saw this issue with GROUP BY and count(m.key) but now I can't reproduce. Hopefully we'll fix all cases.

> Key: IGNITE-12229
> URL: https://issues.apache.org/jira/browse/IGNITE-12229
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Affects Versions: 2.7.6
> Reporter: Ilya Kasnacheev
> Priority: Major
>
> Consider the following SQL:
> {code}
> create table main (key varchar primary key, val int, grouper int);
> create table joiner (key varchar primary key, value int, grouper int);
> select m.key, case when m.grouper > j.grouper then 1 else -1 end d_grouper from main m join joiner j on m.key = j.key where d_grouper = 1 order by d_grouper;
> {code}
> Expected behavior - success.
> Observed behavior:
> {code}
