Subject [jira] Commented: (HIVE-801) row-wise IN would be useful
Date Tue, 11 May 2010 20:32:41 GMT

    [ https://issues.apache.org/jira/browse/HIVE-801?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12866317#action_12866317

Namit Jain commented on HIVE-801:
---------------------------------

Do you want to reuse GenericUDFField.java - or create some common utility and use that.
Also, why do you have a test 

SELECT key FROM src WHERE key IN ("238", 86);


in udf_in.q 

> row-wise IN would be useful

> ...IN would operate on a given row, and return True when the first argument equaled at
least one of the other arguments. So here IN would return true if 12345=key1 OR 12345=key2
OR 12345=key3 (but wouldn't test the latter two if the first matched).
> This would also help with https://issues.apache.org/jira/browse/HIVE-783, if IN were
implemented in a manner that allows it to be used in an ON clause.
