Timothy Potter updated SOLR-9372:
---------------------------------
Component/s: Parallell SQL
> Different data types returned depending on the aggregation mode used to
> execute a SQL statement
> -----------------------------------------------------------------------------------------------
>
> Key: SOLR-9372
> URL: https://issues.apache.org/jira/browse/SOLR-9372
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Parallell SQL
> Affects Versions: 6.1
> Reporter: Timothy Potter
> Labels: sql
>
> The type of aggregation fields returned differs based on the aggregation
> mode. Here's an example:
> {code}
> curl --data-urlencode 'stmt=SELECT movie_id, COUNT(*) as agg_count,
> avg(rating) as avg_rating, sum(rating) as sum_rating, min(rating) as
> min_rating, max(rating) as max_rating FROM movielens_ratings GROUP BY
> movie_id ORDER BY movie_id asc'
> "http://localhost:8984/solr/movielens_ratings/sql?aggregationMode=facet";
> {"result-set":{"docs":[
> {"min_rating":1.0,"avg_rating":3.8783185840707963,"sum_rating":1753.0,"movie_id":"1","agg_count":452,"max_rating":5.0},
> {"min_rating":1.0,"avg_rating":3.831460674157303,"sum_rating":341.0,"movie_id":"10","agg_count":89,"max_rating":5.0},
> {"min_rating":1.0,"avg_rating":4.155511811023622,"sum_rating":2111.0,"movie_id":"100","agg_count":508,"max_rating":5.0},
> {"min_rating":2.0,"avg_rating":3.0,"sum_rating":30.0,"movie_id":"1000","agg_count":10,"max_rating":4.0},
> {"min_rating":1.0,"avg_rating":2.0,"sum_rating":34.0,"movie_id":"1001","agg_count":17,"max_rating":5.0},
> {"min_rating":1.0,"avg_rating":1.875,"sum_rating":15.0,"movie_id":"1002","agg_count":8,"max_rating":4.0},
> {"min_rating":1.0,"avg_rating":2.25,"sum_rating":18.0,"movie_id":"1003","agg_count":8,"max_rating":4.0},

> {code}
> The rating field is an integer in Solr (TrieIntField) so one would expect the
> sum, min, max functions to return Long type but when using
> aggregationMode=facet, we get back doubles. Data types should be consistent
> so client applications don't have to account for this weirdness.
