從sqlite表中刪除一行

Question

我正在從sqlite表中刪除一行，而行在我做錯的地方沒有刪除，請建議我。

public void deleteBName(String id) 
    {
// TODO Auto-generated method stub
        SQLiteDatabase db = this.getWritableDatabase(); 
        db.delete(EmergencyTable, colID + "=" + id, null);
    }

Answer 1

嘗試這個：

 //---deletes a particular title---
public boolean deleteTitle(String name) 
{
    return db.delete(DATABASE_TABLE, KEY_NAME + "=" + name, null) > 0;
}

-

public void deleteBName(String id) 
    {
// TODO Auto-generated method stub
        SQLiteDatabase db = this.getWritableDatabase(); 
        return db.delete(EmergencyTable, colID + "=" + id, null);
    }

Answer 2

也許您的EmergencyTable或colID錯誤。
