当我尝试使用该应用程序时，我收到以下消息。
sqlite returned: error code = 1, msg = no such column: TELEPHONE,**
这是我的代码：

当我尝试启动应用程序时，我收到以下消息。 sqlite返回：错误代码= 1，msg =没有这样的列：TELEPHONE，**
答案 0 :(得分：2)
您有两个选择：
public DatabaseOpenHelper(Context aContext) { super(aContext, DATABASE_NAME, null, 2); }
这将调用OnUpgrade（）方法删除你的Db并再次创建。
