connect to the data source with or without Connection object

[John Davis]

To connect the ASP application to data source, we can use ADO.Connection
object

Const connectionString = "Provider=Microsoft.Jet.OLEDB.3.51; Data
Source=C:\mydatabase.mdb;"
Dim objConn
Set objConn = Server.CreateObject("ADODB.Connection")
....
objConn.Open connectionString
objRS.Open sqlStatement, objConn '----------------- (1)


The alternative is we can open the connection directly with ADO.RecordSet
object, without using ADO.Connection object.

objRS.Open sqlStatement, connectionString '---------------(2)


What's the differences between line (1) and (2)? I read a book saying using
Connection object is expensive, but I don't got it since there is connection
anyway by using RecordSet object.

Please advice. Thanks
John
