java操作Oracle数据库——ARRAY、TABLE类型批量入库
欢迎技术交流。 QQ：138986722
首先是我的数据库表(PLSQL操作)
create table TEST_TABLE ( yid NUMBER, ytel VARCHAR2(50), yanumber VARCHAR2(50) );
这里记录两种方式：不管哪种方式、一定要记得导入orai18n.jar否则一遇到字符串就乱码、添加不到数据
第一种：在数据库中建立相应的java对象(Oracle中的类型)和数组.
CREATE OR REPLACE TYPE yOracleObject(类型名称) AS OBJECT(
yid number,ytel varchar2(50),yanumber varchar2(50)
);数组：CREATE OR REPLACE TYPE y_Oracle_LIST(数组名称) AS VARRAY(5000) OF yOracleObject(类型名称);创建完毕后在Types下面可以看到创建好的类型。
存储过程：
CREATE OR REPLACE PROCEDURE proc_test_new(y_Array IN y_oracle_list,
p_out OUT NUMBER) AS
v_yID number;
v_yTel varchar(50);
v_anumber varchar(50);
v_type yoracleobject;
begin
FOR I IN 1 .. y_Array.COUNT LOOP
v_type := y_Array(i);
v_yID := v_type.yid;
v_yTel := v_type.ytel;
v_anumber := v_type.yanumber;
insert into test_table values (v_yID, v_yTel, v_anumber);
end loop;
commit;
p_out := 0;
EXCEPTION
WHEN OTHERS THEN
p_out := -1;
ROLLBACK;
END;

}第二种：不用判断list集合大小、不用考虑数组长度的做法就是用table。
使用的类型：你要新增的数据有多少字段就添加相应个数的类型
create or replace type i_table is table of number; create or replace type t_table is table of varchar2(30); create or replace type a_table is table of varchar2(30);存储过程:
create or replace procedure pro_forall_insert(v_1 i_table,
v_2 t_table,
v_3 a_table) as
begin
forall i in 1 .. v_1.count
insert into test_table values (v_1(i), v_2(i), v_3(i));
