Subject [jira] [Created] (HIVE-3490) Implement * or a.* for arguments to UDFs
Date Thu, 20 Sep 2012 02:06:08 GMT
Adam Kramer created HIVE-3490:

             Summary: Implement * or a.* for arguments to UDFs
                 Key: HIVE-3490
             Project: Hive
          Issue Type: Bug
          Components: Query Processor, UDF
            Reporter: Adam Kramer

For a random UDF, we should be able to use * or a.* to refer to "all of the columns in their
natural order." This is not currently implemented.

I'm reporting this as a bug because it is a manner in which Hive is inconsistent with the
SQL spec, and because Hive claims to implement *.

hive> select all_non_null(a.*) from table a where a.ds='2012-09-01';
FAILED: ParseException line 1:25 mismatched input '*' expecting Identifier near '.' in expression
