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();

    }
