inserting data into tajo warehouse

[Tarun Kumar]

Hi,

I couldn't locate anything on http://wiki.apache.org/tajo/QueryLanguage for
inserting data into existing table directly (not from any other existing
table).

I tried :

insert into table1 values(1);        // this table has only one column - id
int
insert overwrite into table1 values(1);

None of these seem to work.

Also, is there any way to alter table also?
