JDBC 批量插入记录

1.Statement:提供addBatch(String sql) 和 excuteBatch()方法批量更新数据

               Statement smt=....

                smt.addBatch("insert into talbename...");

                smt.addBatch("sql 语句2");

                smt.addBatch("sql 语句3);

                 ................

                smt.executeBatch();                  //批量执行

2     使用PreparedStatement  

                 PreparedStatement    psmt=conn.perparedStatement("insert into tablename values(?)");

                                psmt.setString(0,"aaa");

                               psmt.addBatch();

                             psmt.setString(0,"bbb");

                              psmt.addBatch(0,"aaa");

                              ......................

                             psmt.executeBatch();
