Oracle数据库Java批量插入数据实战

1.//批量添加20000条数据用时8秒。  
2.try {  
3.   String url = "jdbc:oracle:thin:@IP:1521:orcl"; // orcl为数据库的SID  
4.   String user = "oracle";  
5.   String password = "oracle";  
6.   StringBuffer sql = new StringBuffer();  
7.   sql.append("insert into ex_log (EX_LOG_ID,EX_LOG_DATE) values (?,?)");  
8.   Class.forName("oracle.jdbc.driver.OracleDriver");  
9.   Connection con = (Connection) DriverManager.getConnection(url,user,password);  
10.   // 关闭事务自动提交  
11.   con.setAutoCommit(false);  
12.  
13.   Long startTime = System.currentTimeMillis();  
14.   PreparedStatement pst = (PreparedStatement) con.prepareStatement(sql.toString());  
15.   for (int i = 0; i < list.size(); i++) {  
16.    ExLog exLog = (ExLog)list.get(i);  
17.    pst.setString(1, exLog.getExLogId());  
18.    pst.setString(2, exLog.getExLogDate());  
19.    // 把一个SQL命令加入命令列表  
20.    pst.addBatch();  
21.   }  
22.   // 执行批量更新  
23.   pst.executeBatch();  
24.   // 语句执行完毕，提交本事务  
25.   con.commit();  
26.   Long endTime = System.currentTimeMillis();  
27.   System.out.println("用时：" + (endTime - startTime));  
28.   pst.close();
