Updating 3 Rows (fixed) Using 1 UPDATE Statement - vb.net

Question

So far I have this code updating only 1 row but is there a way to specify the three rows? (3 different ID's)
Public Shared Sub UpdatePrice(ByVal NewPrice As Decimal, ByVal id As Integer)
Dim dtoffenseinfo As New DataTable
If Not DBConnection.State = ConnectionState.Open Then
'open connection
DBConnection.Open()
Else
End If
cmd.Connection = DBConnection
cmd.CommandText = "UPDATE tblStockPrice " & _
" SET Price=" & NewPrice & " WHERE id=" & id & ""
cmd.ExecuteNonQuery()
DBConnection.Close()
End Sub
I assume I need 2 more parameters for the other two rows and that would be fine.

You can use one UPDATE statement with an appropriate WHERE clause to affect multiple records but, if you want to affect each record differently, calling ExecuteNonQuery once is not a very good option. Just create one command with appropriate parameters and then you can set the Value of each parameter multiple times to affect multiple records, e.g.
Using connection As New SqlConnection("connection string here"),
command As New SqlCommand("UPDATE MyTable SET Price = #Price WHERE Id = #Id", connection)
Dim priceParameter = command.Parameters.Add("#Price", SqlDbType.Money)
Dim idParameter = command.Parameters.Add("#Id", SqlDbType.Int)
Dim prices = {12.45, 132.67, 9.8}
Dim ids = {1, 19, 56}
connection.Open()
For i = 0 To 2
priceParameter.Value = prices(i)
idParameter.Value = ids(i)
command.ExecuteNonQuery()
Next
End Using
