[jira] [Commented] (CASSANDRA-5648) Cassandra: Insert of null value not possible with CQL3?

["Aleksey Yeschenko (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-5648?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13685633#comment-13685633 ] 

Aleksey Yeschenko commented on CASSANDRA-5648:
----------------------------------------------

Yeah, only PK columns are required. COMPACT STORAGE is an exception, but I don't think this was intentional and I don't see a reason to not support it. Also, not sure about the correctness of current null-handling in COMPACT STORAGE case. Will have to think about it.

> Hi there,
> I'm trying to migrate a project from thrift to cql3/java driver and I'm experiencing a strange problem.
> Schema:
> {code}
> CREATE TABLE foo (
>   key ascii,
>   column1 ascii,
>   foo ascii,
>   PRIMARY KEY (key, column1)
> ) WITH COMPACT STORAGE;
> {code}
> The table just consists of a primary key and a value, sometimes all the information lies in the key though, so the value is not needed.
> Through the thrift interface, it just works fine to leave out "foo".
> Executing this query:
> {code}
> INSERT INTO foo(key, column1) VALUES ('test', 'test2');
> {code}
> Fails with
> "Bad Request: Missing mandatory column foo"
> though.
> Explicitly inserting "null" as a value does not store the column / deletes the old one with a "null" value inserted through thrift.
> Inserting an empty String works fine, but this seems a bit bloated.
> Is this intended to (not) work this way?
> Best,
> Tobias
