Subject [jira] [Commented] (CASSANDRA-8797) Tuple relation in select query is broken
Date Fri, 13 Feb 2015 15:09:13 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8797?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14320208#comment-14320208

Philip Thompson commented on CASSANDRA-8797:
--------------------------------------------

I can reproduce this on 2.0-HEAD. It's unclear if this type of query is supported. Tyler will
be able to confirm, and fix the exception regardless.

Thank you for the detailed reproduction steps.

> 1) Login to CQLSH
> 2) Create a keyspace as below:
> {{CREATE TABLE test1 (campId int,grpId int,itmtypeId int, itemId int, PRIMARY KEY((campId,
grpId), itmtypeId, itemid));}}
> 3) Insert 10 rows
> 4) Run {{select * from test1}} and it works
> 5) Run a select query as below:
> {{select * from test1 where token(campid, grpid) = token(987654321, 4) and (itmtypeid,
itemid) > (12347, 1234567812);}}
> It fails with error 'TSocket read 0 bytes'
