java_sql_Batch_批处理

java  JDBC 进行sql语句的批处理的两种方法示例代码。表是oracle数据库里的dept表，为了看清逻辑关系，把异常都throws 出去。

 package com.ayang.jdbc;

 import java.sql.*;

 public class TestBatch {

     //为看清逻辑关系，throws出去
     public static void main(String[] args) throws Exception {
         Class.forName("oracle.jdbc.driver.OracleDriver");
         Connection  conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:ORCL","scott","root");

         /**
          * 批处理 方法一：
          */
         /*Statement stmt = conn.createStatement();
         stmt.addBatch("insert into dept2 values(51,'JAVA','XC')");
         stmt.addBatch("insert into dept2 values(52,'PHP','ZZ')");
         stmt.addBatch("insert into dept2 values(53,'C++','XINYANG')");

         stmt.executeBatch();
         stmt.close();*/

         /**
          * 批处理  方法二：
          */
         PreparedStatement  ps =  conn.prepareStatement("insert into dept2 values(?,?,?)");
          ps.setInt(1, 54);
          ps.setString(2, "haha");
          ps.setString(3, "HangZhou");
          ps.addBatch();

          ps.setInt(1, 55);
          ps.setString(2, "haha");
          ps.setString(3, "HangZhou");
          ps.addBatch();

          ps.setInt(1, 56);
          ps.setString(2, "haha");
          ps.setString(3, "HangZhou");
          ps.addBatch();
          ps.executeBatch();
          ps.close();

         conn.close();

     }

 }
