Subject [jira] Commented: (HIVE-259) Add PERCENTILE aggregate function
Date Thu, 28 Jan 2010 22:35:34 GMT

    [ https://issues.apache.org/jira/browse/HIVE-259?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12806134#action_12806134

Jerome Boulon commented on HIVE-259:
------------------------------------

It will also be good to be able to ask for more than one PERCENTILE(column, .99) with only
one single structure in memory
ex: select PERCENTILE(column, .99), PERCENTILE(column, .50) from myTable;
