very useful new feature in Oracle 23ai is the ability to insert multiple row values in one shot, unlike older releases where you need to repeat the SQL command multiple times for each row insertion.
To illustrate:
create table sh1.dummy (fname varchar2(20));
insert into sh1.dummy values (’emad’),
(‘ricardo’),
(‘john’);

Then, you can query the whole table to verify:
select * from sh1.dummy;
