我收到这个错误 -
07-03 12:29:18.643: E/SQLiteLog(5181): (1) table accounts has no column named otherNotes
这是我的代码:

在我的应用程序中，数据库位于资产文件夹中。现在，我想从第二个版本中的assets文件夹更新数据库。
我尝试将代码升级为：
// Data Base Version.
private static final int DATABASE_VERSION = 2;
我将版本从1更改为2。
//构造函数
public DataBaseHelperClass(Context myContext) {
super(myContext, DATABASE_NAME, null ,DATABASE_VERSION);
this.context = myContext;
//The Android's default system path of your application database.
DB_PATH = "/data/data/com.example.myapp/databases/";

//check if the database exists
boolean databaseExist = checkDataBase();

表名称具有类似的后缀。前缀取决于用户输入。现在，在android中，如何在不丢失先前数据的情况下在这些表中添加新列？
即使在卸载应用程序然后重新安装它之后,也不会调用onCreate方法.
Database.java:
public class Database extends SQLiteOpenHelper {
public static SQLiteDatabase db;
public Database(Context context) {
super(context,"db", null, 1);
Log.i("DB", "dbManager");
}
@Override
public void onCreate(SQLiteDatabase db) {
Log.i("DB", "dbOnCreate");
String s = "CREATE TABLE test(id INTEGER);";
db.execSQL(s);
}
@Override
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i1) {
Log.i("DB", "dbOnUpgrade");
}
}
我这叫:
Database db = new Database(this);
输出:
07-17 12:42:03.053 16448-16448/com.package.app I/DB:dbManager
这个问题是什么以及如何解决？
这是我的数据库帮助程序类的代码,任何人都可以告诉我,我在做什么错误,表中没有添加电子邮件列,每次我收到错误,表没有cloumn名称person_email
