Insert not through any file

[VanHuy Pham]

Hi All,
   Is it possible to insert and/or update some data in a hive table not
through any local file?
   To be specific, I look to insert and update some data (not large amount)
to a hive table through queries (like insert into...) in a traditional SQL
style, where you specify the new data in the queries.
   I only found INSERT or LOAD where you have to specify SELECT...from some
other tables or files, and did not find any UPDATE.
   Any ideas?

Thanks
