oracle存储过程插入百万数据

创建表

create  table sjbjsource1(  

        ID    NUMBER(10) NOT NULL PRIMARY KEY,  

        NAME VARCHAR(50),

        time1  timestamp

    ); 

创建存储过程

create or replace procedure insert_sjbj is

i number;

begin

i:=0;

loop

  i:=i+1;

  if i>1000000 then

    exit;

  end if;

  insert into sjbjsource1(id,name,time1) values(i,i,sysdate);

 

end loop;
end insert_sjbj;

为表创建自增字段

 CREATE SEQUENCE sjbjs_sequence  

    INCREMENT BY 1  

    START WITH 1  

    NOMAXVALUE  

    NOCYCLE  

    NOCACHE;

    

    

    CREATE TRIGGER "sjbjs_trigger" BEFORE  

    INSERT ON sjbjsource1 FOR EACH ROW WHEN(new.id is null)  

    BEGIN  

    select sjbjs_sequence.nextval into:new.id from dual;  

    end;
