问使用提供的数据库使用SQLite进行onUpgrade时更新特定表

EN

@Override
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i2) {
    if(i < i2) {
        SQLiteDatabase db = SQLiteDatabase.openDatabase(DB_PATH + DB_NAME, null,SQLiteDatabase.OPEN_READWRITE);
        db.execSQL("attach database ? as newdb", new String[]{DB_PATH + DB_NAME}); // I have to attach new version of db to the old one and then i can go on
        db.execSQL("delete from GAME");
        db.execSQL("INSERT INTO GAME SELECT * FROM newdb.GAME");
        db.close();
}

db.execSQL("INSERT INTO GAME SELECT * FROM newdb.GAME");
