Subject [jira] [Commented] (DRILL-1903) Boolean column can't be used by itself in certain condition in a where clause
Date Mon, 16 Mar 2015 16:39:38 GMT

    [ 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!
