> Add Aggregation support for Fluo/PCJ app
> ----------------------------------------
>
> Key: RYA-260
> URL: https://issues.apache.org/jira/browse/RYA-260
> Project: Rya
> Issue Type: New Feature
> Reporter: Andrew Smith
> Assignee: Kevin Chilton
>
> A user must be able to submit a PCJ query that contains the following
> aggregation functions from SPARQL:
> * Sum
> * Count
> * Average
> * Min
> * Max
> This task does not include any aggregations that appear within a GroupBy
> clause. We only need to support queries that have the aggregation within the
> SELECT section.
> For example, the following query should be processed:
> {code}
> SELECT (avg(?price) as ?averagePrice)
> {
> urn:BookA urn:price ?price.
> }
> {code}
> And the following query should not be processed because it requires a group
> by:
> {code}
> SELECT ?title (avg(?price) as ?averagePrice)
> {
> ?title urn:price ?price.
> }
> GROUP BY ?title
> {code}
