Sqllite query returns cursor with 0 rows

Question

I am trying to retrieve data using query from the sqlite database that was previously populated. But for some reason the query returnscursor with no rows.

So here is the portion where I tried to retrieve data:

        database.open();
    Cursor cursor = database.getComponentData("CONTROLS", null, null);

    int test = cursor.getCount();//This is the part where i test through the eclipse debugger whether there is  any rows return
    cursor.moveToFirst();
    while (!cursor.isAfterLast()) {

        get.append("Video controls : "+cursor.getString(1)+" Audio Controls : "+cursor.getString(2)+" Reader controls : "+cursor.getString(3));
        cursor.moveToNext();
    }
    cursor.close();
    Cursor cursor1 = database.getComponentData("LIST", new String[]{"'URL'"},"AUDIO");

    get.append("Video list : ");
        cursor1.moveToFirst();
    while (!cursor1.isAfterLast()) {

        get.append(" "+cursor1.getString(1)+" "+cursor1.getString(2)+" "+cursor1.getString(3));
        cursor1.moveToNext();

    }
    cursor1.close();
    database.close();

And here is the portion in the database adapter where I queried.

public Cursor getComponentData(String whichTable,String[] whichColumn,String whichSection) {
    Cursor c = null;
    if(whichSection!=null) 
    {   
        return database.query(whichTable, whichColumn,"SECTION = '"+whichSection+"'",null, null, null, null);
    }
    else{
        return database.query(whichTable, whichColumn,null,null, null, null, null);
    }

}

This is the portion where i insert into the database previously:

                 database.open();
               ContentValues control = new ContentValues();
               control.put("VIDEO_CONTROLS",video_control);
               control.put("AUDIO_CONTROLS",audio_control);
               control.put("READER_CONTROLS",book_control);

               control_long =database.insertNewControl(control);

               ContentValues temp_list = new ContentValues();

                a_p=audio_playlist.split(",");
                v_p=video_playlist.split(",");
                b_p=booklist.split(",");
               for(int i =0;i<a_p.length;i++){
                   temp_list.put("NAME", "test");
                   temp_list.put("URL", a_p[i]);
                   temp_list.put("SECTION", "AUDIO");

                list_long=   database.insertNewListRow(temp_list);

               }
               for(int i =0;i<v_p.length;i++){
                  temp_list.put("NAME", "test");
                   temp_list.put("URL", v_p[i]);
                   temp_list.put("SECTION", "VIDEO");
                   list_long=    database.insertNewListRow(temp_list);

                   }
               for(int i =0;i<b_p.length;i++){
                 temp_list.put("NAME", "test");
                   temp_list.put("URL", b_p[i]);
                   temp_list.put("SECTION", "READER");
                   list_long=   database.insertNewListRow(temp_list);

                   }
                database.close();

Insert Methods in the Adapter:

    public Long insertNewControl(ContentValues controls_values) {
return database.insert("CONTROLS", null, controls_values);  
}
public Long insertNewListRow(ContentValues list_values){
return database.insert("LIST", null, list_values);  
}

Thanks for reading.

Edit : Forgotten to mention this, If I were to query() from the database right after I have inserted these rows, I would be able to get rows out.But I were to query for these rows after I close() and open() again, cursor returns no rows.

Answer 1

I forgotten to post the solution that i found ,

Basically what happen is that I forgotten to name the database at the constructor of the class where the database and tables were created. epicfacepalm
