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

点击下载orai18n.jar

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));
END;

{
Object[] s1 = new Object[10000];

DbUtil工具类：

import java.io.IOException;
import java.io.InputStream;
import java.sql.Connection;
import java.sql.DriverManager;
import java.util.Properties;

public class DbUtil {
static Properties properties = null;

public DbUtil() {
// 读取.properties文件的信息
properties = new Properties();
InputStream in = getClass().getResourceAsStream("/com/chinaboxun/ordermanager/config/ordermanager.properties");
try {
properties.load(in);
} catch (IOException ex) {
System.out.println(ex.getMessage());
ex.printStackTrace();
}
}

/**
* <LI>获取连接对象</LI>
*
* @return
*/
public Connection getCon() {
Connection connection = null;
try {
String url=properties.getProperty("jdbc.url");
String user=properties.getProperty("jdbc.username");
String pwd=properties.getProperty("jdbc.password");
String driver=properties.getProperty("jdbc.driverClassName");
Class.forName(driver);
connection = DriverManager.getConnection(url, user, pwd);
} catch (Exception err) {
System.out.println("错误：ConDB-->getCon()____JDBC连接失败!");
err.printStackTrace();
return null;
}
return connection;
}
}

ordermanager.properties属性文件：

jdbc.driverClassName=oracle.jdbc.OracleDriver
jdbc.url=jdbc:oracle:thin:@172.16.0.162:1521:ORCL
jdbc.username=m_order
jdbc.password=morder

最后：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！

我被这个可整惨了！

尼玛、老子这牙齿疼死我了！！！
