 Description   

In MDEV-26635 was changed behavior for ROW_NUMBER, but in view we still get 1 instead 0:
Test:

create view v1 as SELECT CAST('.00000000000000000000000000000000000001e111111111111111111111' AS DECIMAL(38,0)) AS a;
 
select * from v1;
 
drop view v1;

Expected result:

a
 
99999999999999999999999999999999999999
