  • NUL symbol gets inserted anywhere in the XML

    - by Racs
    I am using Oracle 11g and when I query data from database manually, it looks ok. But when I view it using Notepad++, there is a special character that gets inserted anywhere in the xml produced. Please see image below: I tried everything and deleted some parts of the xml, updated the db and query again but the invalid character just differ in location. Any idea is much appreciated, thanks! Best regards, Racs

  • NullPointerException while trying to bind at SimpleCursorAdapter

    - by hrskrs
    I have asked a question before where i found my mistake. However now i am facing with another problem. I have checked all the similar errors asked on StackOverflow but without success.Any help is appriciated. The idea here is that i am getting image names from DB so depending on those names images from Drawable folder will be shown in a listView together with a description but im getting an error of NullPointException at setViewValue. Here is the code snippet: private void populateListView() { ListView customListView = (ListView)findViewById(R.id.lvCustom); Cursor cursor = DBhelper.getAllimages(); startManagingCursor(cursor); String[] from = { DBhelper.COLUMN_PIC_URL, DBhelper.COLUMN_PIC_DESC}; int[] to = {R.id.ivImg, R.id.tvTitle}; SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(this, R.layout.custom_listview_row, cursor, from, to, 0); cursorAdapter.setViewBinder(new ViewBinder() { @Override public boolean setViewValue(View view, Cursor cursor, int columnIndex) { ImageView imageImageView = (ImageView)findViewById(R.id.ivImg); String[] imgNames = new String[cursor.getCount()]; int[] imgResourceIds = new int[cursor.getCount()]; for(int i=0; i<cursor.getCount(); i++){ imgNames[i] = cursor.getString(cursor.getColumnIndex(DBhelper.COLUMN_PIC_URL)); imgResourceIds[i] = getResources().getIdentifier(imgNames[i], "drawable", getPackageName()); imageImageView.setImageResource(imgResourceIds[i]); cursor.moveToNext(); } return true; } }); customListView.setAdapter(cursorAdapter); } Here is the Error from LogCat: I have tried to log the output of imgNames[i] where it returns the url pic from the DB correctly and imgResourceIds[i] where it return the image resource id correctly also(it does not return NULL but something like: 295731). But it stops at imageImageView.setImageResource(imgResourceIds[i]); To see from where that NullPointerException is coming, i commented out imageImageView.setImageResource(imgResourceIds[i]);. This time imageNames(those with a TAG) and imgResourceIds(those system printed out) came correctly but doubled, when i removed cursor.MoveToNext() last row were doubled. Here is the screen shot of that: I have tried all the suggestions on stack about gettin a NullException but without success. Any idea where i am doing mistake?

  • Check mysql_query results if DELETE query worked?

    - by Camran
    I have a DELETE query which deletes a record from a mysql db. is there any way to make sure if the delete was performed or not? I mean, for a query to FIND stuff you do $res=mysql_query($var); $nr=mysql_num_rows($res); and you get nr of rows returned. Is there any similiar method for deletion of records? Thanks

  • Check value existance while performing a UPDATE query

    - by nimo
    Hi, I need to perform a simple update query where the update should only be done, if there is no value with updating value (item_name). For example, DB table [item_types] item_id(PK) | item_name Assuming there exist item_id with 6, My attempt is UPDATE item_types as k SET k.item_name = 'item_1' WHERE NOT EXISTS (SELECT * FROM item_types as a WHERE a.item_name = 'item_1') AND k.item_id = '6' But this gives me error "You can't specify target table 'k' for update in FROM clause" Could you please explain the error here and how can I achieve this ? Thank you

  • Multiple reference in SQL

    - by AGarofoli
    Hi! I'm working on a db but i'm kinda new to this so i've bumped into a problem today. I've got some tables: OFFICE, ROOM, EMPLOYEE and DOCUMENT. Document must specify the sender, which can be a single employee, an entire room or an entire office so it must have a reference to the primary keys of those tables. Should I do a "parallel" table for handle it (for example i've done one for handle the multiple recipients documents) or there is another way? Thank you
