oracle大批量添加测试数据实例

一、Test Windos方式
declare

　　maxrecords constant int:=100000;

　　i int :=1;

　　begin

　　for i in 1..maxrecords loop

　　insert into test2

　　(id, name)

　　values

　　(test2_seq.nextval, to_char(9999+i));

　　end loop;

　　dbms_output.put_line(' 成功录入数据!');

　　commit;

　　end;

　二、从已有表中往入另一张表导数据
create or replace procedure TestProc is

　　begin

　　for c in(select id, name from test2) loop

　　insert into test

　　(id,

　　name)

　　values

　　(test_seq.nextval, c.name);

　　end loop;

　　end TestProc;
