----------------------------------------
Summary: Query with expression is giving wrong result
Key: CARBONDATA-2029
URL: https://issues.apache.org/jira/browse/CARBONDATA-2029
Project: CarbonData
Issue Type: Bug
Reporter: kumar vishal
Assignee: kumar vishal
Create Maintable:
CREATE TABLE mainTable(id int, name string, city string, age string) STORED BY
'org.apache.carbondata.format
Create datamap
create datamap agg1 on table mainTable using 'preaggregate' as select
name,sum(id) from mainTable group by name
Load data
Run query :select sum(id)+count(id) from maintable is giving wrong result
Problem: When query has expression it is not checking which aggregate function
is applied on table and based on table it is selecting aggregate table
Solution: While extracting the aggregate expression from query plan in case if
any expression is present extract which aggregate function applied on column to
select the aggregate table
