Description

You can create a table with an interval type via create table as select but not directly with create table.

This works

create table test_interval 
as 
select  interval '1' day as day_interval, 
        interval '1' month as month_interval;

describe test_interval;
+-----------------+----------------------+----------+--+
|    col_name     |      data_type       | comment  |
+-----------------+----------------------+----------+--+
| day_interval    | interval_day_time    |          |
| month_interval  | interval_year_month  |          |
+-----------------+----------------------+----------+--+

This raises an error.

create table test_interval(                                                         
   day_interval 	interval_day_time,                                                   
   month_interval 	interval_year_month
   );
