java pgsql 批量delete java数据库批量提交

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;

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

}

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;

import java.sql.Connection;
import java.sql.SQLException;
import java.util.ArrayList;
import com.chinaboxun.ordermanager.core.util.DbUtil;

		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;

				cstmt = con.prepareCall("{ call pro_forall_insert(?,?,?) }");
				cstmt.setObject(1, a_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.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!

----------------编辑:20140110---------------

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
