             Summary: Limiting a clustering column with a range not allowed when using "group
by"
                 Key: CASSANDRA-14376
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14376
             Project: Cassandra
          Issue Type: Bug
          Components: CQL
         Environment: Cassandra 3.11.1
            Reporter: Chris mildebrandt


I’m trying to use a range to limit a clustering column while at the same time using `group
by` and running into issues. Here’s a sample table:

{{create table if not exists samples (name text, partition int, sample int, city text, state
text, count counter, primary key ((name, partition), sample, city, state)) with clustering
order by (sample desc);}}

When I filter `sample` by a range, I get an error:

{{select city, state, sum(count) from samples where name='bob' and partition=1 and sample>=1
and sample<=3 group by city, state;}}
{{{color:#FF0000}InvalidRequest: Error from server: code=2200 [Invalid query] message="Group
by currently only support groups of columns following their declared order in the PRIMARY
KEY"{color}}}

However, it allows the query when I change from a range to an equals:

{{select city, state, sum(count) from samples where name='bob' and partition=1 and sample=1
group by city, state;}}

{{city | state | system.sum(count)}}
{{--------+-------+-------------------}}
{{ Austin | TX | 2}}
{{ Denver | CO | 1}}
