saulfrank opened a new issue #8123: SQL where equals subquery cannot build query plan
URL: https://github.com/apache/incubator-druid/issues/8123
 
 
   
   ### Affected Version
   
   Version 0.15.0
   
   ### Description
   This query produces: Unknown exception (org.apache.druid.java.util.common.ISE): Cannot build plan for query
   
   select * from "druid"."table"
   where __time = (
   select max(__time) as file_date from "druid"."table")
   
   I also tried this on the date field but got the same:
   
   select * from "druid"."table"
   where file_date = (
   select max(file_date) as file_date from "druid"."table")
   
   I would have thought this would work?
