Naveen Gangam commented on HIVE-27749:
--------------------------------------
[~sbadhya] This seems to be broken since alpha-2 due to
https://github.com/apache/hive/pull/3369
Is there a solution that works for both MySQL and MariaDB.
ALTER TABLE `NOTIFICATION_SEQUENCE` MODIFY COLUMN `NNI_ID` BIGINT(20) GENERATED
ALWAYS AS (1) STORED NOT NULL;
According to MariaDB docs, it should work.
https://mariadb.com/kb/en/generated-columns/#examples
I tried removing the NOT NULL keyword based on the error message but MariaDb
does not seem to support generated columns for PK.

ALTER TABLE `NOTIFICATION_SEQUENCE` MODIFY COLUMN `NNI_ID` BIGINT(20) GENERATED
ALWAYS AS (1) STORED NOT NULL;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MariaDB server version for the right syntax to use near
'NOT NULL' at line 1
MariaDB [naveen]> ALTER TABLE `NOTIFICATION_SEQUENCE` MODIFY COLUMN `NNI_ID`
