[jira] [Commented] (CARBONDATA-4047) Datediff datatype is not working with spark-2.4.5. even in spark-sql its showing as null. .Either the query might be wrong or the versions don't support datatypes.

Akash R Nilugal commented on CARBONDATA-4047:
---------------------------------------------

The query you have given is wrong, stored as should come first.

correct query would be
1. CREATE TABLE IF NOT EXISTS vestedlogs3 STORED AS carbondata as (select * , intck ("Hours", 'StartTimestamp', 'CompleteTimestamp') as Hours FROM vestedlogs) 

This will also fail, as spark doesnt have intck function, it fails for parquet also, you can check.

2. rewrite the query 
CREATE TABLE IF NOT EXISTS vestedlogs3  STORED AS carbondata as (SELECT *,DATEDIFF(HOUR,StartTimestamp GETDATE(),CompleteTimestamp GETDATE()) AS "Hours" FROM vestedlogs)

after this again fails for parsing, please check your query again
and can refer

spark doesnt support all, you can check for alternative
