SQLiteException：沒有這樣的列itemId：，而編譯時：

public ArrayList<Entry> getCurrentEntries(){

public void addEntry(Entry e){

} 

public long getLineNumber() { 
    return lineNumber; 
} 

public void setLineNumber(long lineNumber) { 
    this.lineNumber = lineNumber; 
} 
}

當我嘗試運行此代碼我得到一個錯誤我沒有任何想法請幫助。SQLiteException：沒有這樣的列itemId：，而編譯時：

android.database.sqlite.SQLiteException：沒有這樣的列：ITEMID：，在編譯：選擇的itemId，項目類型，itemValues，itemBustype，itemLighttype，itemSelected FROM light_setting_items ORDER BY itemSelected，ITEMTYPE

你CREATE TABLE命令沒有工作，因爲有在關閉前有一個逗號)。

此外，SQLiteOpenHelper不會調用您的onCreate方法爲現有的數據庫;您將不得不增加VERSION並在onUpdate方法中進行必要的更改。或者，刪除並重新安裝您的應用程序。

我刪除它，但仍然無法正常工作 – mystery

非常感謝;我刪除並重新安裝了應用程序，它運行 – mystery
