Aleksey Yeschenko commented on CASSANDRA-3783:
----------------------------------------------
There isn't, and inserting nulls via both INSERT and UPDATE works fine for me, prepared and
not, cassandra-1.2.4 and 1.2.5.
Is your Cassandra cluster at 1.2.4+? If yes, then it must be a cass-jdbc issue. Do the same
queries work fine in cqlsh?

> Dense composite supports adding records where only a prefix of all the component specifying
the key is defined. In other words, with:
> {noformat}
> CREATE TABLE connections (
> userid int,
> ip text,
> port int,
> protocol text,
> time timestamp,
> PRIMARY KEY (userid, ip, port, protocol)
> ) WITH COMPACT STORAGE
> {noformat}
> you can insert
> {noformat}
> INSERT INTO connections (userid, ip, port, time) VALUES (2, '192.168.0.1', 80, 123456789);
> {noformat}
> You cannot however select that column specifically (i.e, without selecting column (2,
'192.168.0.1', 80, 'http') for instance).
> This ticket proposes to allow that though 'null', i.e. to allow
> {noformat}
> SELECT * FROM connections WHERE userid = 2 AND ip = '192.168.0.1' AND port = 80 AND protocol
= null;
> {noformat}
> It would then also make sense to support:
> {noformat}
> INSERT INTO connections (userid, ip, port, protocol, time) VALUES (2, '192.168.0.1',
80, null, 123456789);
> {noformat}
> as an equivalent to the insert query above.
