SQLiteException：临近＆QUOT;在数据库中插入null时与QUOT;：语法错误 [英] SQLiteException: near "null": syntax error when inserting in database

问题描述

好日子，只是为了简短有关code，

Good day, Just to make it short with relevant code,

如果我这样做在我的活动：

If i do this in my activity:

     Intent i = getIntent();
          Bundle extras = i.getExtras();

          BitmapFactory.Options bf = new BitmapFactory.Options();
          bf.inSampleSize = 2;


          filename = extras.getString("pic_name");
          ImageView  iv = new ImageView(getApplicationContext());
          Bitmap bm = BitmapFactory.decodeFile(filename, bf);
          iv.setImageBitmap(bm);
          setContentView(iv);

  registerForContextMenu(iv);



public boolean onContextItemSelected(MenuItem item){
       // weatherimagedb = new WeatherImageDB(this);
        //weatherimagedb.open();

        ContentValues vals = new ContentValues();
        int selection = item.getItemId();
        switch(selection){
        case Holidays:

             vals.put(ImageDB.HOLIDAYS, filename);

        break;
        case Weather:
            vals.put(ImageDB.WEATHER, filename);

        break;
        }
             imagedb.tagImage(filename, vals); //logcat error is here

  return true;
}

和中下，imageDB数据库类我有这样一个方法：

And in the imageDB database class i have a method like this:

public long tagImage(String pathname, ContentValues val){  
    return db.insert(DATABASE_TABLE, null, val);    //logcat error is here

}

我得到这个数据库的错误，但它不会崩溃我的应用程序：

i get this error in database, but it does not crash my app:

什么可能我是做错了吗？..我不能使用ContentValues​​正确就够了吗？

what could i be doing wrong please?.. am i not using the ContentValues correctly enough?

感谢您。

推荐答案

难道说你的选既不是假期也不天气？

Could it be that your selection is neither Holidays nor Weather?
