J2ME+PointBase

PointBase使用方法(也许是J2ME程序员你急切想了解)

1.下载玩数据库以后还要记得从自己邮箱里下载lisecens
2.在dos模式下进入在你下载并解压的目录下执行 Java -classpath ./install.jar install
3.装上pointbase然后将lisecens考到安装目录下。(lisences千万不要改不然程序连接时会出错)
4.将PointBase的lib加入到你的工程中,如果你使用EclipseMe的话请安装以下步骤操作。
  选择Project->properties菜单


5.如果工程重要使用PointBase那么还要将这些类引入到工程中来
6.好了尽情使用你的PonitBase吧
         try {
            Class.forName("com.pointbase.me.DriverManager");
             Connection conn=DriverManager.getConnection(
                "jdbc:pointbase:micro:test","PBPUBLIC","PBPUBLIC");
            Statement stat=conn.createStatement();
            DatabaseMetaData meta=conn.getMetaData();
            ResultSet rs=meta.getTables(null,null,"TEST",null);
            if(rs.next()) {
                // the table already exists
                stat.execute("UPDATE TEST SET ID=ID+1");
            } else {
                // the table doesn't exist yet
                stat.execute("CREATE TABLE TEST(ID INT)");
                stat.execute("INSERT INTO TEST VALUES(1)");
            }
            rs=stat.executeQuery("SELECT ID FROM TEST");
            rs.next();
            int count=rs.getInt(1);
            System.out.println("Hello Database!");
            System.out.println("This application was run "+count+" time(s)");
            conn.close();
        } catch(Exception e) {
            e.printStackTrace();
        }
