Nishant Bangarwa created CALCITE-2319:
-----------------------------------------
Summary: Druid Expressions - Output Type of Boolean expressions
should be set to FLOAT.
Key: CALCITE-2319
URL: https://issues.apache.org/jira/browse/CALCITE-2319
Project: Calcite
Issue Type: Bug
Reporter: Nishant Bangarwa
Assignee: Nishant Bangarwa
Sample Query -
{code}
SELECT \"product_id\" > 1000 as pid_category, COUNT(\"store_sales\") FROM
FOODMART_TABLE GROUP BY \"product_id\" > 1000";
{code}
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.
{code}
"{"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"]}"
