Subject [jira] [Commented] (ASTERIXDB-1528) Query 6 in AsterixDB 101 is broken
Date Thu, 14 Jul 2016 18:54:20 GMT

    [ https://issues.apache.org/jira/browse/ASTERIXDB-1528?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15378127#comment-15378127
] 

Michael J. Carey commented on ASTERIXDB-1528:
---------------------------------------------

But is-null should also still work - no?  (I thought null, missing, and the generalization
unknown were all supported?)

> Query 6 in the 101 tutorial is:
> use dataverse TinySocial;
> for $fbu in dataset FacebookUsers
> where (some $e in $fbu.employment satisfies is-null($e.end-date))
> return $fbu;
> This query no longer returns the expected results shown in the tutorial; instead it returns
the empty set.  (If you replace is-null with is-missing it works though.)
