SQL & PL/SQL

DB version: 11.2.0.4

I have a table and a sequence like below.

create table t (t_id number , t_c2 varchar2(35) );

create sequence t_id_generator

minvalue 1

maxvalue 9999999999

start with 1

increment by 1

cache 100

noorder

nocycle;

I want to run the below INSERT statement in a loop for 1 minute and then COMMIT. Any idea how I can do this ?

insert into t values (t_id_generator.nextval, 'a');
