Not able to show all data fetch from sqlite db into Expandable list view

I am inserting data from .csv file into sqlite database.But when I am fetching data from sqlite & showing it into Expandable list view,it skips some row data and showing in Expandable list view i.e. Some data is missing while showing from sqlite to Expandable list view

Main Activity

    databaseHelper = new DatabaseHelper(this);
    listDataHeader = new ArrayList<String>();
    childDataHashMap = new HashMap<String, List<ChildInfo>>();`
    // get the listview
    expListView = (ExpandableListView) findViewById(R.id.expandableListView);

    // ****************************Group data******************************//
    Cursor cursor = databaseHelper.getExpandableData();
    cursor.moveToFirst();
    Log.i(TAG, "cursor.getCount()" + cursor.getCount());
    do {
        Log.d(TAG,"Category "+ cursor.getString(cursor  .getColumnIndex("categorydesc")));
        String categoryDescription = cursor.getString(cursor    .getColumnIndex("categorydesc"));
        int categoryId = cursor.getInt(cursor.getColumnIndex("CategoryId"));
        Log.i(TAG, "categoryDescription:" + categoryDescription);
        listDataHeader.add(categoryDescription);

        // ****************************Child data******************************//
        Cursor cursorChild = databaseHelper.fetchChildren(categoryId);
        List<ChildInfo> childList = new ArrayList<ChildInfo>();
        cursorChild.moveToFirst();
        while (cursorChild.moveToNext()) {
            String businessName = cursorChild.getString(cursorChild .getColumnIndex("BusinessName"));
            phoneNumber = cursorChild.getString(cursorChild.getColumnIndex("ph_Phone"));
            String landMark = cursorChild.getString(cursorChild.getColumnIndex("LandMark"));
            Log.w("", "Category Child " + businessName);
            ChildInfo childInfo = new ChildInfo(businessName, phoneNumber,landMark);
            childList.add(childInfo);
        }
        childDataHashMap.put(categoryDescription, childList);
    } while (cursor.moveToNext());
    cursor.close(); 
    listAdapter = new ExpandableListAdapterNew(this, listDataHeader,childDataHashMap);
    // setting list adapter
    expListView.setAdapter(listAdapter);

Database Helper

    /** Fetch group. 
     * @return the cursor
     */
    public Cursor fetchGroup() {
        //String query = "SELECT DISTINCT CategoryId, categorydesc FROM Category ";
    String query = "SELECT  DISTINCT CategoryId, categorydesc, FROM Category";
        Cursor res = db.rawQuery(query, null);
        return res;
    }

    /** Gets the expandable data. 
     * @return the expandable data
     */
    public Cursor getExpandableData() {
        String query = "SELECT * FROM Category GROUP BY categorydesc";
        return db.rawQuery(query, null);
    }
