Question

I am using the following code and getting the error below

      select d.searchpack,d.context, d.day,d,txnid,d.config, c.sgtype from ds3resultstats d join       
     context_header c on (d.context=c.contextid) where (d.day>='2012-11-15' and d.day<='2012-11-25' and  c.sgtype='Tickler' and d.config like 
'%people%') GROUP BY d.context limit 10;
        FAILED: Error in semantic analysis: line 1:7 Expression Not In Group By Key d

I am guessing I am using the group by incorrectly

Answer 1

when you use group by, you cannot select other additional field. You can only select group key with aggregate function.

See hive group by for more information.

Code example:

select d.context,count(*)
from ds3resultstats
...
group by d.context

or group by multiply fields.

select d.context, d.field2, count(*)
from ds3resultstats
...
group by d.context, d.field2
