> returns varchar( 20 )
> language java parameter style java deterministic no sql
> external name 'java.lang.Integer.toString'

> create table orders
> (
> orderID bigint primary key,
> salesPrice int not null,
> region generated always as ( getRegion( salesPrice ) )
> )
> ;
> create table dummy( a int );
> create trigger newOrderTrigger
> after insert on orders
> for each row
> insert into dummy( a ) values ( 1 )
