Description

Sample Query -

 
SELECT \"product_id\" > 1000 as pid_category, COUNT(\"store_sales\") FROM FOODMART_TABLE GROUP BY \"product_id\" > 1000";

For the above query output type of virtual column is set to string whereas it should be set to float as druid expression return type is float.

"{"queryType":"groupBy","dataSource":"foodmart","granularity":"all","dimensions":[{"type":"default","dimension":"vc","outputName":"vc","outputType":"STRING"}],"virtualColumns":[{"type":"expression","name":"vc","expression":"(CAST(\"product_id\", 'LONG') > 1000)","outputType":"FLOAT"}],"limitSpec":{"type":"default"},"aggregations":[{"type":"filtered","filter":{"type":"not","field":{"type":"selector","dimension":"store_sales","value":null}},"aggregator":{"type":"count","name":"EXPR$1","fieldName":"store_sales"}}],"intervals":["1900-01-09T00:00:00.000Z/2992-01-10T00:00:00.000Z"]}"
