Muhammad Gelbana updated DRILL-5197:
------------------------------------
    Description: 
The following query fails for no obvious reason
{code:sql}
SELECT
   CASE
      WHEN `tname`.`full_name` = 'ABC' 
      THEN
( 
         CASE
            WHEN `tname`.`full_name` = 'ABC' 
            THEN
               (
                  CASE
                     WHEN `tname`.`full_name` = ' ' 
                     THEN
                        (
                           CASE
                              WHEN `tname`.`full_name` = 'ABC' 
                              THEN `tname`.`full_name` 
                              ELSE NULL 
                           END
                        )
                        ELSE NULL 
                  END
               )
               ELSE NULL 
         END
         )
         WHEN `tname`.`full_name` = 'ABC' 
         THEN NULL 
         ELSE NULL 
   END
FROM
   cp.`employee.json` `tname`
{code}
If the `THEN `tname`.`full_name`` statements is changed to `THEN 'ABC'` the error does not
occur.
