java 操作Oracle 批量入库的问题
先说下我运行的环境:
Windows7 64位操作系统
(四核)Intel i5-2300 CPU @2.80GHz
内存4G
硬盘1T
Jdk1.6+MyEclipse8.6 for Spring+ojdbc14.jar
Oracle10.2.0+PLSQL7.1.4.1390
情况是这样的,今天一个朋友说用了我说的Oracle的Table类型批量入库过后,感觉慢了点。为此我在不考虑多线程的情况下,分别用“Oracle的 自定义类型定义表类型”、“Oracle的基本类型定义表类型”、“JDBCBATCH”一次性向Oracle插入10000条数据的用时进行了测试。结 果让我很费解。在这里列出来,希望知道的能解答一下,万分感谢。
数据表:
数据表:
-- Create table
create table DATE_JH_INC_UDR_01
(
SERIAL_NUMBER VARCHAR2(16) not null,
OPR_TYPE VARCHAR2(10) not null,
SERV_CODE VARCHAR2(10) not null,
SP_CODE VARCHAR2(10) not null,
OPER_CODE VARCHAR2(20) not null,
INPUT_START_DATE DATE,
INPUT_END_DATE DATE,
OPR_TIME DATE,
EFF_TIME DATE not null,
OPR_SOURCE VARCHAR2(10),
THIRD_DN VARCHAR2(30),
CHRG_TYPE VARCHAR2(10)
);
-- Create/Recreate primary, unique and foreign key constraints
alter table DATE_JH_INC_UDR_01
add constraint PK_DATE_JH_INC_UDR_01 primary key (SERIAL_NUMBER, OPR_TYPE, SERV_CODE, SP_CODE, OPER_CODE, EFF_TIME);
-- Create/Recreate indexes
create index IDX_DATE_JH_INC_UDR_011 on DATE_JH_INC_UDR_01 (SP_CODE, OPER_CODE);
一、采用Oracle“基本类型”定义表类型入库。

二、采用Oracle“自定义类型”定义表类型入库。
数据库类型准备:
--创建一个Object类型

OPR_SOURCE NVARCHAR2(10),
THIRD_DN NVARCHAR2(30),
CHRG_TYPE NVARCHAR2(10)
);
--创建一个Table类型——对象表
CREATE OR REPLACE TYPE t_d_type AS TABLE OF o_d_type;
/*
* 批量入库存储过程
*/
CREATE OR REPLACE PROCEDURE ARRAY_TO_IBOSS_UDR(V_1 IN T_D_TYPE, --table类型参数
O_ERR OUT VARCHAR2,
SUCC_COUNT OUT NUMBER,
FAIL_COUNT OUT NUMBER) AS
I INTEGER;
V_TYPE O_D_TYPE; --object 类型变量
BEGIN
I := 0;
SUCC_COUNT := 0;
FAIL_COUNT := 0;
WHILE I < V_1.COUNT LOOP
BEGIN
I := I + 1;
V_TYPE := V_1(I); --将table里的值赋给object
INSERT INTO DATE_JH_INC_UDR_01
VALUES
(V_TYPE.SERIAL_NUMBER,
V_TYPE.OPR_TYPE,
V_TYPE.SERV_CODE,
V_TYPE.SP_CODE,
V_TYPE.OPER_CODE,
TO_DATE(V_TYPE.INPUT_START_DATE, 'YYYY-MM-DD HH24:MI:SS'),

V_TYPE.OPR_SOURCE,
V_TYPE.THIRD_DN,
V_TYPE.CHRG_TYPE);
SUCC_COUNT := SUCC_COUNT + 1;
EXCEPTION
WHEN OTHERS THEN
FAIL_COUNT := FAIL_COUNT + 1;
O_ERR := I || ':' || SQLERRM;
END;
END LOOP;
END;

import java.sql.CallableStatement;

import java.util.ArrayList;
import java.util.List;
import oracle.jdbc.OracleConnection;
import oracle.sql.ARRAY; public class Test {
/**
* @param args
*/
@SuppressWarnings("unchecked")
public static void main(String[] args) {
System.out.println("----------这是使用Oracle“自定义类型”定义表类型入库--------");
long datebegin = System.currentTimeMillis();
try{
int succcount=0;
int failcount=0; long datebegin1 = System.currentTimeMillis();
List s = new ArrayList();
for (int i = 0; i < 10000; i++) {
Object[] o1 = new Object[12];
o1[0] = "0"+i;
o1[1] = "0";
o1[2] = "0";

}
long end1 = System.currentTimeMillis();
System.out.println("组装list用时:"+(end1-datebegin1)+"毫秒"); long date1 = System.currentTimeMillis();
OracleConnection conn = null;
CallableStatement cstmt = null;
oracle.sql.ArrayDescriptor a = null;
Class.forName("oracle.jdbc.driver.OracleDriver");
conn = (OracleConnection)DriverManager.getConnection("jdbc:oracle:thin:@"+"127.0.0.1"+":1521:"+"orcl", "test", "root");

} }
执行之前清除数据:TRUNCATE TABLE DATE_JH_INC_UDR_01;
测试结果:
三、采用“JDBCBATCH”进行批量入库。
数据库不用存储过程,就一张表放在那里就好
Java程序:
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.sql.Date;
import java.util.List; import oracle.jdbc.OracleConnection; public class Jdbc { /**
* @param args
* @throws ClassNotFoundException
* @throws SQLException
* @throws ParseException
*/
public static void main(String[] args) throws ClassNotFoundException, SQLException, ParseException {
System.out.println("----------这是使用JDBC入库--------");
long datebegin = System.currentTimeMillis();
List<Object[]> s = new ArrayList<Object[]>();
for (int i = 0; i < 10000; i++) {
Object[] o1 = new Object[12];
o1[0] = "0"+i;
o1[1] = "0";
o1[2] = "0";
o1[3] = "0";
o1[4] = "0";
o1[5] = "20131226";
o1[6] = "20131226";
o1[7] = "20131226";
o1[8] = "20131226";
o1[9] = "0"+i;
o1[10] = "0";
o1[11] = "0";
s.add(o1);
}
long end1 = System.currentTimeMillis();
System.out.println("组装list用时:"+(end1-datebegin)+"毫秒"); long date1 = System.currentTimeMillis();
Class.forName("oracle.jdbc.driver.OracleDriver");
OracleConnection conn = null;
conn = (OracleConnection)DriverManager.getConnection("jdbc:oracle:thin:@"+"127.0.0.1"+":1521:"+"orcl", "test", "root");
String sql = "INSERT INTO DATE_JH_INC_UDR_01 VALUES (?,?,?,?,?,?,?,?,?,?,?,?)";
PreparedStatement ps = conn.prepareStatement(sql);
long date2 = System.currentTimeMillis();
System.out.println("数据库连接准备用时:"+(date2-date1)+"毫秒"); long array1 = System.currentTimeMillis();
//设置1w条提交一次
/*final int batchSize = 10000;
int count = 0;*/
for (Object[] obj: s) {
ps.setString(1, obj[0].toString());
ps.setString(2, obj[1].toString());
ps.setString(3, obj[2].toString());
ps.setString(4, obj[3].toString());
ps.setString(5, obj[4].toString());
ps.setDate(6, getDate(obj[5].toString()));
ps.setDate(7, getDate(obj[6].toString()));
ps.setDate(8, getDate(obj[7].toString()));
ps.setDate(9, getDate(obj[8].toString()));
ps.setString(10, obj[9].toString());
ps.setString(11, obj[10].toString());
ps.setString(12, obj[11].toString());
ps.addBatch();
/*if(++count % batchSize == 0) {
ps.executeBatch();
}*/
}
long array2 = System.currentTimeMillis();
System.err.println("组装SQL用时:"+(array2-array1)+"毫秒"); long params1 = System.currentTimeMillis();
ps.executeBatch();
long params2 = System.currentTimeMillis();
System.out.println("执行用时:"+(params2-params1)+"毫秒"); long cl1 = System.currentTimeMillis();
ps.close();
conn.close();
long cl2 = System.currentTimeMillis();
System.out.println("关闭用时:"+(cl2-cl1)+"毫秒"); long end = System.currentTimeMillis();
System.out.println("入库总用时:"+(end-datebegin)+"毫秒"+" 秒数为:"+((end-datebegin)/1000.0));
} public static Date getDate(String str) throws ParseException{
SimpleDateFormat df = new SimpleDateFormat("yyyyMMdd");
return new Date(df.parse(str).getTime());
} }
执行之前清除数据:TRUNCATE TABLE DATE_JH_INC_UDR_01;
测试结果:
这让我灰常怀疑Oracle做这个数据接口出来干什么?
几个问题,想问问大家。
第一,对这种大批量的数据入库,各位采用的都是用什么方式+多线程?
第二,Oracle提供ARRAY跟TABLE跟OBJECT类型拿来入库的话,是不是性能真的像我测试这样?
第三,如果你们用的不是JDBC的Batch方法,并且比它更快的,贴出来让我学习学习吧!
第四,这里不考虑多线程问题,当然实际应用中多线程肯定要加上去的。
第五,向看过我Oracle的ARRAY,TABLE类型批量入库的并且还拿到生产环境上去使用的同学致以歉意,是我坑了你们......
