Adam Kramer created HIVE-3490:
---------------------------------
Summary: Implement * or a.* for arguments to UDFs
Key: HIVE-3490
URL: https://issues.apache.org/jira/browse/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 specification
