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。

 1 package com.ayang.jdbc;
 2 
 3 import java.sql.*;
 4 
 5 
 6 public class TestBatch {
 7 
 8     //为看清逻辑关系，throws出去
 9     public static void main(String[] args) throws Exception {
10         Class.forName("oracle.jdbc.driver.OracleDriver");
11         Connection  conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:ORCL","scott","root");
12         
13         /**
14          * 批处理 方法一：
15          */
16         /*Statement stmt = conn.createStatement();
17         stmt.addBatch("insert into dept2 values(51,'JAVA','XC')");
18         stmt.addBatch("insert into dept2 values(52,'PHP','ZZ')");
19         stmt.addBatch("insert into dept2 values(53,'C++','XINYANG')");
20         
21         stmt.executeBatch();
22         stmt.close();*/
23         
24         /**
25          * 批处理  方法二：
26          */
27         PreparedStatement  ps =  conn.prepareStatement("insert into dept2 values(?,?,?)");
28          ps.setInt(1, 54);
29          ps.setString(2, "haha");
30          ps.setString(3, "HangZhou");
31          ps.addBatch();
32          
33          ps.setInt(1, 55);
34          ps.setString(2, "haha");
35          ps.setString(3, "HangZhou");
36          ps.addBatch();
37          
38          ps.setInt(1, 56);
39          ps.setString(2, "haha");
40          ps.setString(3, "HangZhou");
41          ps.addBatch();
42          ps.executeBatch();
43          ps.close();
44          
45         conn.close();
46 
47     }
48 
49 }
