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。
数据库准备:
数据库准备: CREATE OR REPLACE TYPE D_SERIAL_NUMBER IS TABLE OF NVARCHAR2(16); CREATE OR REPLACE TYPE D_OPR_TYPE IS TABLE OF NVARCHAR2(2); CREATE OR REPLACE TYPE D_SERV_CODE IS TABLE OF NUMBER(10); CREATE OR REPLACE TYPE D_SP_CODE IS TABLE OF NVARCHAR2(10); CREATE OR REPLACE TYPE D_OPER_CODE IS TABLE OF NVARCHAR2(20); CREATE OR REPLACE TYPE D_INPUT_START_DATE IS TABLE OF NVARCHAR2(25); CREATE OR REPLACE TYPE D_INPUT_END_DATE IS TABLE OF NVARCHAR2(25); CREATE OR REPLACE TYPE D_OPR_TIME IS TABLE OF NVARCHAR2(25); CREATE OR REPLACE TYPE D_EFF_TIME IS TABLE OF NVARCHAR2(25); CREATE OR REPLACE TYPE D_OPR_SOURCE IS TABLE OF NVARCHAR2(2); CREATE OR REPLACE TYPE D_THIRD_DN IS TABLE OF NVARCHAR2(30); CREATE OR REPLACE TYPE D_CHRG_TYPE IS TABLE OF NVARCHAR2(2); CREATE OR REPLACE PROCEDURE ARRAY_TO_IBOSS_UDR2(V_1 D_SERIAL_NUMBER,V_2 D_OPR_TYPE,V_3 D_SERV_CODE,V_4 D_SP_CODE,V_5 D_OPER_CODE,V_6 D_INPUT_START_DATE,V_7 D_INPUT_END_DATE,V_8 D_OPR_TIME,V_9 D_EFF_TIME,V_10 D_OPR_SOURCE,V_11 D_THIRD_DN,V_12 D_CHRG_TYPE,O_ERR OUT VARCHAR2,SUCC_COUNT OUT NUMBER,FAIL_COUNT OUT NUMBER) AS I INTEGER; BEGIN I:=0; SUCC_COUNT:=0; FAIL_COUNT:=0; WHILE I<V_1.COUNT LOOP BEGIN I:=I+1; INSERT INTO DATE_JH_INC_UDR_01 VALUES(V_1(I),V_2(I),V_3(I),V_4(I),V_5(I),TO_DATE(V_6(I),‘YYYY-MM-DD HH24:MI:SS‘),TO_DATE(V_7(I),‘YYYY-MM-DD HH24:MI:SS‘),TO_DATE(V_8(I),‘YYYY-MM-DD HH24:MI:SS‘),TO_DATE(V_9(I),‘YYYY-MM-DD HH24:MI:SS‘),V_10(I),V_11(I),V_12(I)); SUCC_COUNT:=SUCC_COUNT+1; EXCEPTION WHEN OTHERS THEN FAIL_COUNT:=FAIL_COUNT+1; O_ERR := I||‘:‘||SQLERRM; END; END LOOP; END;

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 CREATE OR REPLACE TYPE o_d_type AS OBJECT ( SERIAL_NUMBER NVARCHAR2(16), OPR_TYPE NVARCHAR2(10), SERV_CODE NVARCHAR2(10), SP_CODE NVARCHAR2(10), OPER_CODE NVARCHAR2(20), INPUT_START_DATE NVARCHAR2(30), INPUT_END_DATE NVARCHAR2(30), OPR_TIME NVARCHAR2(30), EFF_TIME NVARCHAR2(30), 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‘), TO_DATE(V_TYPE.INPUT_END_DATE, ‘YYYY-MM-DD HH24:MI:SS‘), TO_DATE(V_TYPE.OPR_TIME, ‘YYYY-MM-DD HH24:MI:SS‘), TO_DATE(V_TYPE.EFF_TIME, ‘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;
Java代码:
import java.sql.CallableStatement; import java.sql.DriverManager; 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"; 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-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"); a = oracle.sql.ArrayDescriptor.createDescriptor("T_D_TYPE", conn); long date2 = System.currentTimeMillis(); System.out.println("数据库连接准备用时:"+(date2-date1)+"毫秒"); long array1 = System.currentTimeMillis(); ARRAY a_test = new ARRAY(a, conn, s.toArray()); long array2 = System.currentTimeMillis(); System.err.println("组装ARRAY用时:"+(array2-array1)+"毫秒"); long params1 = System.currentTimeMillis(); cstmt = conn.prepareCall("{ call array_to_iboss_udr(?,?,?,?) }"); cstmt.setObject(1, a_test); cstmt.registerOutParameter(2, java.sql.Types.VARCHAR); cstmt.registerOutParameter(3, java.sql.Types.NUMERIC); cstmt.registerOutParameter(4, java.sql.Types.NUMERIC); long params2 = System.currentTimeMillis(); System.out.println("设置参数用时:"+(params2-params1)+"毫秒"); long exe1 = System.currentTimeMillis(); cstmt.execute(); long exe2 = System.currentTimeMillis(); System.err.println("执行用时:"+(exe2-exe1)+"毫秒"); long cl1 = System.currentTimeMillis(); String error_info = cstmt.getString(2); succcount = succcount+cstmt.getInt(3); failcount = failcount+cstmt.getInt(4); if(error_info!=null)System.out.println(error_info); cstmt.close(); conn.close(); long cl2 = System.currentTimeMillis(); System.out.println("获取返回参数及关闭用时:"+(cl2-cl1)+"毫秒"); } catch(Exception e){ e.printStackTrace(); } long end = System.currentTimeMillis(); System.out.println("入库总用时:"+(end-datebegin)+"毫秒"+" 秒数为:"+((end-datebegin)/1000.0)); } }
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......
