Question 21: You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.
The application contains a DataSet object named OrderDS that has the Order and OrderDetail tables as
shown in the following exhibit.
You write the following code segment. (Line numbers are included for reference only.)
01 Private Sub GetOrders(ByVal cn As SqlConnection)
02 Dim cmd As SqlCommand = cn.CreateCommand()
03 cmd.CommandText = "Select * from [Order]; " + _
"Select * from [OrderDetail];"
04 Dim da As New SqlDataAdapter(cmd)
05
06 End Sub
You need to ensure that the Order and the OrderDetail tables are populated.
Which code segment should you insert at line 05?
A. da.Fill(OrderDS)
B. da.Fill(OrderDS.Order)
da.Fill(OrderDS.OrderDetail)
C. da.TableMappings.AddRange(New DataTableMapping() _
{New DataTableMapping("Table", "Order"), _
New DataTableMapping("Table1", "OrderDetail")})
da.Fill(OrderDS)
D. Dim mapOrder As New DataTableMapping()
mapOrder.DataSetTable = "Order"
Dim mapOrderDetail As New DataTableMapping()
mapOrder.DataSetTable = "OrderDetail"
da.TableMappings.AddRange(New DataTableMapping() _
{mapOrder, mapOrderDetail})
da.Fill(OrderDS)
