Subject [jira] [Commented] (CASSANDRA-7105) SELECT with IN on final column of composite and compound primary key fails
Date Tue, 13 May 2014 01:07:15 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13995910#comment-13995910
] 

Dave Brosius commented on CASSANDRA-7105:
-----------------------------------------

a slighly easier example to follow is

{code}
create table test (a int, b int, c int, primary key ((a, b), c)) with clustering order by
(c desc);
insert into test (a, b, c) values (1, 2, 3);
insert into test (a, b, c) values (4, 5, 6);

select a, b, c from test3 where a= 1 and b = 2 and c in (3);
correctly returns 1 row

but 

select a, b, c from test3 where a= 1 and b = 2 and c in (3,4);
fails to return the row
{code}

When the clustering column is ASC, it performs correctly.

> As you can see, when I specify IN on the final primary column, no rows are returned,
even when I specify equality on the partition column.  If I use IN to constrain the partition
column but simple equality on the final column, one row is returned for each of the possible
values.  
> This appears to be a variation on Cassandra-6327 but with a String as the final primary
key column.  I initially saw this with a blob as the final primary key column, so the issue
is not exclusive to String.  When I tried a real simple case with ints throughout, that worked
fine.
