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
