>                 Key: HIVE-1002
>                 URL: https://issues.apache.org/jira/browse/HIVE-1002
>             Project: Hadoop Hive
>          Issue Type: New Feature
>            Reporter: Zheng Shao

> We should allow queries like this into a partitioned table:
> {code}
> CREATE TABLE (a STRING, b STRING, c STRING)
> PARTITIONED BY (ds STRING, ts STRING);
> INSERT OVERWRITE TABLE x PARTITION (ds = '2009-12-12')
> SELECT a, b, c, ts FROM xxx;
> {code}
> Basically, allowing users to overwrite multiple partitions at a time.
> The partition values specified in PARTITION part (if any) should be a prefix of the partition
keys.
> The rest of the partition keys goes to the end of the SELECT expression list.
