Java DB:“表”没有名为“名称列”的列

我在启动应用程序时遇到此问题，它导致我出现以下错误：

可能您必须提高数据库版本

递增后，将调用onUpgrade方法

因此，您可以将所有表放到这里，然后调用onCreate

范例

public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IF EXISTS firstTable");
    db.execSQL("DROP TABLE IF EXISTS secondTable");
    db.execSQL("DROP TABLE IF EXISTS thirdTable");
    onCreate(db);
}

尝试创建一个新的DB表。您最近是否在数据库中没有该列的情况下运行应用程序，并且未能更改数据库版本以通知应用程序重新创建该表？该列肯定是在上一次应用程序运行后添加的。只需从设备卸载应用程序并重新运行即可解决您的问题您是否尝试卸载并安装应用程序再一次

public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IF EXISTS firstTable");
    db.execSQL("DROP TABLE IF EXISTS secondTable");
    db.execSQL("DROP TABLE IF EXISTS thirdTable");
    onCreate(db);
}
