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;

java代码：

import java.sql.CallableStatement;import java.sql.Connection;import java.sql.SQLException;import java.util.ArrayList;import com.chinaboxun.ordermanager.core.util.DbUtil;import oracle.jdbc.driver.OracleCallableStatement;import oracle.sql.ARRAY;import oracle.sql.ArrayDescriptor;import oracle.sql.STRUCT;import oracle.sql.StructDescriptor;@SuppressWarnings("unchecked")public class TestProc {public static void main(String[] args) {ArrayList arrayL = new ArrayList();TestBean t = new TestBean();t.setYid(1);t.setYtel("1236");t.setYanumber("骚年");arrayL.add(t);TestBean t1 = new TestBean();t1.setYid(2);t1.setYtel("1236");t1.setYanumber("骚年");arrayL.add(t1);  TestBean t2 = new TestBean();  t2.setYid(3);t2.setYtel("1236");t2.setYanumber("骚年");arrayL.add(t2);TestBean t3 = new TestBean();t3.setYid(4);t3.setYtel("1236");t3.setYanumber("骚年");arrayL.add(t3);TestBean t4 = new TestBean();t4.setYid(5);t4.setYtel("1236");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、 * 然后剩下的数据又从新用一个list来装、在继续判断...... * 这里只是简单的演示、就不具体操作判断了 */int backVal = newTest(arrayL);System.out.println(backVal==0?"成功!":"失败!");} catch (SQLException e) {e.printStackTrace();}}/** * 将java中的arrayList转化 * @param con 数据库连接对象 * @param Oraclelist 数据数组类型名称 * @param objlist 要存储的list对象 * @return oracle.sql.ARRAY * @throws Exception */private static ARRAY getOracleArray(Connection con, String Oraclelist,ArrayList objlist) throws Exception {ARRAY list = null;if (objlist != null && objlist.size() > 0) {/** * 必须大写类型名称 * 否则会报错：java.sql.SQLException: 无效的名称模式: M_ORDER.yoracleobject */StructDescriptor structdesc = new StructDescriptor("YORACLEOBJECT", con);STRUCT[] structs = new STRUCT[objlist.size()];Object[] result = new Object[0];for (int i = 0; i < objlist.size(); i++) {result = new Object[3]; TestBean t = (TestBean)(objlist.get(i));result[0] = t.getYid();result[1] = t.getYtel();  result[2] = t.getYanumber(); /* * 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 */structs[i] = new STRUCT(structdesc, con, result);}ArrayDescriptor desc = ArrayDescriptor.createDescriptor(Oraclelist,con);list = new ARRAY(desc, con, structs);} else {ArrayDescriptor desc = ArrayDescriptor.createDescriptor(Oraclelist,con);STRUCT[] structs = new STRUCT[0];list = new ARRAY(desc, con, structs);}return list;} /** * 入库 * @param peoleList 要存储的list对象 * @return * @throws SQLException */public static int newTest(ArrayList peoleList) throws SQLException{Connection con = null;CallableStatement stmt = null;int backVal = -1; try {DbUtil d = new DbUtil();con = d.getCon();if (con != null) {stmt = con.prepareCall("{call proc_test_new(?,?)}");ARRAY adArray = getOracleArray(con, "Y_ORACLE_LIST",peoleList);((OracleCallableStatement) stmt).setARRAY(1, adArray);stmt.registerOutParameter(2, java.sql.Types.INTEGER);stmt.execute(); backVal = stmt.getInt(2);}} catch (Exception e) {e.printStackTrace(); } finally {if(stmt!=null){stmt.close();}if(con!=null){con.close();}}return backVal;}}

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) asbegin  forall i in 1 .. v_1.count    insert into test_table values (v_1(i), v_2(i), v_3(i));END;

java代码：

import java.sql.CallableStatement;import java.sql.Connection;import java.sql.SQLException;import java.util.ArrayList;import com.chinaboxun.ordermanager.core.util.DbUtil;import oracle.jdbc.driver.OracleCallableStatement;import oracle.sql.ARRAY;import oracle.sql.ArrayDescriptor;import oracle.sql.STRUCT;import oracle.sql.StructDescriptor;@SuppressWarnings("unchecked")public class TestProc {public static void main(String[] args) {Connection con = null;CallableStatement cstmt = null;oracle.sql.ArrayDescriptor a = null;oracle.sql.ArrayDescriptor b = null;oracle.sql.ArrayDescriptor c = null;DbUtil d = new DbUtil();con = d.getCon();if (1 == 1 ){Object[] s1 = new Object[10000];Object[] s2 = new Object[10000];Object[] s3 = new Object[10000];for (int i = 0; i < 10000; i++) {s1[i] = new Integer(i);s2[i] = "ttt"+i;s3[i] = "aaa"+i;}try {a = oracle.sql.ArrayDescriptor.createDescriptor("I_TABLE", con);b = oracle.sql.ArrayDescriptor.createDescriptor("T_TABLE", con);c = oracle.sql.ArrayDescriptor.createDescriptor("A_TABLE", con);ARRAY a_test = new ARRAY(a, con, s1);ARRAY b_test = new ARRAY(b, con, s2);ARRAY c_test = new ARRAY(c, con, s3);cstmt = con.prepareCall("{ call pro_forall_insert(?,?,?) }");cstmt.setObject(1, a_test);cstmt.setObject(2, b_test);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.OracleDriverjdbc.url=jdbc:oracle:thin:@172.16.0.162:1521:ORCLjdbc.username=m_orderjdbc.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！

点击下载orai18n.jar

一些加上jar继续报错如下错误的朋友可以考虑以下解决方案：

ERROR1：Non supported character set: oracle-character-set-852

ERROR2：oracle/i18n/text/converter/CharacterConverterOGS.getInstance(I)Loracle/i18n/text/converter/CharacterConverter;

以上两个错误可以采取一个方案，就是把type的数据类型改成：nVARCHAR2

如果坚持使用该jar的童鞋请将 nls_charset12.jar 加入到 classpath 中。在加上orai18n.jar

我被这个可整惨了！

尼玛、老子这牙齿疼死我了！！！
