[jira] [Commented] (DRILL-1903) Boolean column can't be used by
itself in certain condition in a where clause
[ https://issues.apache.org/jira/browse/DRILL-1903?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14363455#comment-14363455 ]
Sean Hsuan-Yi Chu commented on DRILL-1903:
------------------------------------------
For the first failing query : select * from test where c1;
I presume it is because c1 is ANY type at planning. So Calcite decides just not to let it go through!
