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}}
