Fill matrix with query

Question

Hi,
I have a query that I want to display in a matrix. The query is based on the tables: OINV, INV1, OITM, OCRD. I would like to know what is the best way to bind this query to a matrix? Should I create a recordset with the query and iterate it and fill the matrix line by line and column by columns, or can I use something like a datasource with query (even if there are more than one table) and bind it?
And also, can I create this query using the DI API (I haven't worked with it so far) or do I have to create it myself (my own SELECT)?
Thank you so much,
Irina

hi,
create one temporary table called TEMP with all necessary fields which u r going to insert in Matrix.
Use the following code.
delete the existing values in @TEMP table
RS = Nothing
                RS = ocompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset)
                RS.DoQuery("Select * from OITM,OITW,ITT1 where Conditions")
For i as integer = 1 To RS.RecordCount
RS1 = Nothing
RS1 = ocompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset)
RS1.DoQuery("INSERT INTO [@TEMP](DocEntry,U_X,U_Y,U_Z)values(" & i & "," & RS.Fields.Item("ItemCode").Value & "','" & RS.Fields.Item("Quantity").Value & "','" & RS.Fields.Item("UoM").Value & "')")
End If
                DSource = Nothing
                oMatrix = oForm.Items.Item("MatrixUID").Specific
                oColumns = oMatrix.Columns
                DSource = oForm.DataSources.DBDataSources.Add("@TEMP")
                oColumn = oColumns.Item("0") ' # Column
                oColumn.DataBind.SetBound(True, "@TEMP", "DocEntry")
                oColumn = oColumns.Item("1")
                oColumn.DataBind.SetBound(True, "@TEMP", "U_X")
                oColumn = oColumns.Item("2")
                oColumn.DataBind.SetBound(True, "@TEMP", "U_Y")
                oColumn = oColumns.Item("3")
                oColumn.DataBind.SetBound(True, "@TEMP", "U_Z")
                oMatrix.Clear()
                oMatrix.AutoResizeColumns()
                DSource.Query()
                oMatrix.LoadFromDataSource()
or u can use a virtual data source table.this is better.
oForm.DataSources.DataTables.Add("TEMP") 'Virtual data table. You can use as is.
Dim SQLSTR as String  = "SELECT fields FROM tables WHERE Conditions"
oForm.DataSources.DataTables.Item("TEMP").ExecuteQuery(SQLSTR )
                DSource = Nothing
                oMatrix = oForm.Items.Item("MatrixUID").Specific
                oColumns = oMatrix.Columns
                oColumn = oColumns.Item("1")
                oColumn.DataBind.SetBound(True, "TEMP", "U_X")
                oColumn = oColumns.Item("2")
                oColumn.DataBind.SetBound(True, "TEMP", "U_Y")
                oColumn = oColumns.Item("3")
                oColumn.DataBind.SetBound(True, "TEMP", "U_Z")
                oMatrix.Clear()
                oMatrix.AutoResizeColumns()
                DSource.Query()
                oMatrix.LoadFromDataSource()
