Re: SELECT without FROM
It looks like FROM was made optional in Hive 0.13.0 with HIVE-4144 <https://issues.apache.org/jira/browse/HIVE-4144> (thanks Alan Gates to pointing us to the grammar file and Sushanth Sowyman for helping track this down). A note has been added to the wiki <https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Select#LanguageManualSelect-SelectSyntax> about this. Dmitry, you said it didn't work in your Hive 0.13 version, but it seems like the patch was applied to 0.13.0. You might want to take a look at HIVE-4144 and see if that patch was applied to your version. -Shannon Ladymon On Wed, Mar 9, 2016 at 2:13 AM, Mich Talebzadeh wrote: > hm.

SELECT without FROM
I noticed that Hive allows you to execute SELECT without FROM clause (tested in Hive 0.14, Hive 1.2.1): SELECT 1+1; In which version was it added (is there a Jira)? I see that it is not mentioned in docs https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Select So the question whether it is official and will not be removed in future. Thanks, Dmitry
