It looks like this is a known issue
(https://issues.apache.org/jira/browse/HIVE-4173).

yeah.i agree. that doesn't make any sense. why in the world would the "where
clause" not be supported with that syntax? something's rotten in denmark there
with your query.
what version of hive are you seeing this on?

Doesn't INSERT INTO do what you said? I'm not sure I understand "inserting a
few records into a table".
Anyway here the problem seems different to me. For my cases these where clauses
for multiple inserts seem not effective, while Hive doesn't complain about that.

Hive doesn't support inserting a few records into a table. You will need to
write a query to union your select and then insert. IF you can partition, then
you can insert a whole partition at a time instead of the table.

Yes for the example you gave, it works. It even works when there is a single
insert under the from clause, but there there are multiple inserts, the where
clauses seem no longer effective.

Have you simply tried
INSERT OVERWRITE TABLE destination SELECT col1, col2, col3FROM sourceWHERE col4
= 'abc'
Thanks!

Hi Hive Gurus,
When using the Hive extension of multiple inserts, can we add Where clauses for
each Select statement, like the following?
FROM ...
INSERT OVERWRITE TABLE ... SELECT col1, col2, col3 WHERE col4='abc'INSERT
OVERWRITE TABLE ... SELECT col1, col4, col2 WHERE col3='xyz'
The underlined parts didn't cause any errors, but they didn't seem to be
effective either (I'm using Hive 0.9). Note that the columns used in the Where
clauses are not among the selected ones, but I'm not sure if that is important.
Is this kind of operations supported?
Thanks,Sha Liu
