首先建立測試表

　　[email protected]>create table test nologging as select rownum id,a.* from dba_objects a where 1=2;

　　Table created.

　　插入500萬條數據：

　　[email protected]>declare

　　l_cnt number;

　　l_rows number:=&1;

　　begin

　　insert /*+ append */ into test select rownum,a.* from dba_objects a;

　　l_cnt:=sql%rowcount;

　　commit;

　　while(l_cnt

　　loop

　　insert /*+ append */ into test select rownum+l_cnt,

　　owner,object_name,subobject_name,

　　object_id,data_object_id,

　　object_type,created,last_ddl_time,

　　timestamp,status,temporary,

　　generated,secondary

　　from sales

　　where rownum<=l_rows-l_cnt;

　　l_cnt:=l_cnt+sql%rowcount;

　　commit;

　　end loop;

　　end; 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

　　22 /

　　Enter value for 1: 5000000

　　old 3: l_rows number:=&1;

　　new 3: l_rows number:=5000000;

　　PL/SQL procedure successfully completed.
