java操作Oracle数据库——ARRAY、TABLE类型批量入库
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;

- t4.setYanumber("骚年");
- arrayL.add(t4);
- try {
- /*
- * 记得判断一下list集合的大小、如果集合大于你在数据设置的数组大小了、那么就要分批次提交
- * 我的是y_Oracle_LIST AS VARRAY(5000)
- * 那么当list集合的值等于5000的时候就入库了、

- */
- int backVal = newTest(arrayL);
- System.out.println(backVal==0?"成功!":"失败!");
- } catch (SQLException e) {
- e.printStackTrace();
- }
- }
- /**

- private static ARRAY getOracleArray(Connection con, String Oraclelist,
- ArrayList objlist) throws Exception {
- ARRAY list = null;
- if (objlist != null && objlist.size() > 0) {
- /**

- * 否则会报错:java.sql.SQLException: 无效的名称模式: M_ORDER.yoracleobject
- */
- StructDescriptor structdesc = new StructDescriptor(

- }
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;

- cstmt = con.prepareCall("{ call pro_forall_insert(?,?,?) }");

- cstmt.setObject(3, c_test);
- cstmt.execute();
- con.commit();
- } catch (Exception e) {
- e.printStackTrace();
- }
- }

- }

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.jdbc:oracle:thin:@172.16.0.162:1521:ORCL < /span>
- 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!
