测试java的insert 同使用9i以后的bulk Insert 的速度.
测试结果显示通过bulk Insert 速度相当的快.
100000条记录
insert ,---------------93秒
bulk insert -------------0.441秒

环境:
oracle 10.2.0.3 Windows 2000Server?
java

代码:

?

SQL> desc a
Name Type Nullable Default Comments 
---- ------------ -------- ------- -------- 
ID INTEGER Y 
NAME VARCHAR2(20) Y
bulk Insert 使用的类型及过程
create or replace type i_table is table of number(10);
create or replace type v_table is table of varchar2(10);
create or replace procedure pro_forall_insert(v_1 i_table,v_2 v_table)
as
c integer;
begin

forall i in 1.. v_1.count 
insert into a values(v_1(i),v_2(i));
end;
