 Description   

Test:

create view v1 as SELECT CAST('9999-12-31 23:59:59.123456' AS INTERVAL DAY_SECOND(6)) AS a, CAST('00:00:00.99' AS INTERVAL DAY_SECOND(6)) as b;
 
select * from v1;
 
drop view v1;

Expected result:

a	b
 
NULL	00:00:00.990000
 
Warnings:
 
Warning	1292	Incorrect INTERVAL DAY TO SECOND value: '9999-12-31 23:59:59.123456'

Actual result:

a	b
 
9999-12-31 23:59:59.1234	00:00:00.99
 
Warnings:
