Master & Detail Data Report

How can I display the same Master and Detail records in DataReport, using SQL statement?

As detail recrords can be more than one, so how can I display it on report along with master record?

In this code, the master record is also repeating along with detail records.

VB Code:

Dim Rs As New ADODB.Recordset
Set Rs = conServer.Execute("SELECT * FROM MASTER, DETAIL WHERE MASTER.RecNo = DETAIL.MaterialID")
 
With DataReport1
    .DataMember = vbNullString
    Set .DataSource = Rs
    .Caption = "DataReport Window"
 
    With .Sections("Section1").Controls
        .Item("txtDescription").DataField = Rs.Fields(2).Name
        .Item("txtQty").DataField = Rs.Fields(3).Name
        .Item("txtUnit").DataField = Rs.Fields(4).Name
        .Item("txtRate").DataField = Rs.Fields(5).Name
        .Item("txtAmount").DataField = Rs.Fields(6).Name
        '.Item("txtMaterial").DataField = Rs.Fields(7).Name
    End With
    .Show
End With
