oracle循环和过程

--创建表
create table t_test 
(
       test_id varchar2(100),
test_name varchar2(100)
);
--查询
select * from t_test;
truncate table t_test;
--声明过程--配合循环插入测试数据
declare 
v_index number := 1;
begin
        loop
               if v_index < 100 then
                  insert into t_test values ('id'||v_index,'name'||v_index);
                  v_index := v_index + 1;
               else exit;
               end if;
        end loop;       
        commit;
end;
