Subject [jira] [Commented] (HIVE-2608) Do not require AS a,b,c part in LATERAL VIEW
Date Tue, 09 Jul 2013 02:27:48 GMT


Edward Capriolo commented on HIVE-2608:

[~navis]It seems like some other limit optimization work is inside this patch. Is that supposed
to be there?

> Currently, it is required to state column names when LATERAL VIEW is used.
> That shouldn't be necessary, since UDTF returns struct which contains column names -
and they should be used by default.
> For example, it would be great if this was possible:
> SELECT t.*, t.key1 + t.key4
> FROM some_table
> LATERAL VIEW JSON_TUPLE(json, 'key1', 'key2', 'key3', 'key3') t;
