SAP Add On: How to load data from database to a matrix

Question

I am making a payroll application add-on for SAP Business One. I have made a form using screen painter and wanted to know how one goes about loading data from a database into the matrix columns.
My matrix has 6 columns and have called the items;
public void DeclareColumsInMonthlyMatrix()
            SAPbouiCOM.Item oItem = null;
            // Adding the Monthlymatrix Elements
            oItem = _form.Items.Item("matMonthly");
            oMatrix = oItem.Specific;
            oColumns = oMatrix.Columns;
            oColumn = oColumns.Item("mPayYear");
            oColumn = oColumns.Item("mMonth");
            oColumn = oColumns.Item("mStartDate");
            oColumn = oColumns.Item("mEndDate");
            oColumn = oColumns.Item("mPayStatus");
            oColumn = oColumns.Item("mTaxMethod");
I have retrieved the appropriate data from the database using LinQ to SQL and I have:
// Populate the Monthly Period Data Grid View           
    var monthlyPeriods = Program.Kernel.Get<IMonthlyPeriodService>().GetAllMonthlyPeriods();
    monthlyPeriods = monthlyPeriods.OrderBy(x => Enum.Parse(typeof(MonthsOfAYear), x.Code, true));
The corresponding field names in the database for the 6 columns are:
U_Payroll_Year,
    U_Month,
    U_Starting_date,
    U_Ending_date,
    U_Pay_Process_Status,
    U_Tax_Method
I was previously using C# .Net win forms and was using a datagrid and bindingsource which was easy by using the code
// Populate the Monthly Period Data Grid View           
    var monthlyPeriods = Program.Kernel.Get<IMonthlyPeriodService>().GetAllMonthlyPeriods();
    monthlyPeriods = monthlyPeriods.OrderBy(x => Enum.Parse(typeof(MonthsOfAYear), x.Code, true));
    monthlyPeriodBindingSource.DataSource = monthlyPeriods.ToList();
How do I achieve the same in SAP? How do I get the returned results from monthlyperiods to map over the appropriate columns in my matrix?

Hi Nor,
you could build a function which is able to generate a list of koordinates from your geometry.
The file generated will be a character-separated list.
This list will be generated by using a simple select statement like this:
<font color="FFFF00">
select obj_id, mysdo_koo2list(geometry) from my_geotable where ... ;
</font>
the function mysdo_koo2list(..) have to be built by you first.
<em>create function mysdo_koo2list ( gc sdo_geometry) return varchar2 as
line varchar2(4000);
n number;
ordinate number;
begin
line:= ''; n := 0;
for ordinate in gc.sdo_ordinates.FIRST .. geom.sdo_ordinates.LAST
loop
line := line||to_char(geom.sdo_ordinates(ordinate), '9999999D999');
if ( mod(n,2) = 1 ) then
line := line||chr(10);
else
line := line||',';
end if;
n := n +1 ;
-- exit when n >330;
end loop;
return (line);
end;
