Dim OraSession as OraSession

Dim OraDatabase as OraDatabase

Dim OraDynaset as OraDynaset

Dim Person as OraRef

'Create the OraSession Object.

Set OraSession = CreateObject("OracleInProcServer.XOraSession")

'Create the OraDatabase Object by opening a connection to Oracle.

Set OraDatabase = OraSession.OpenDatabase("ExampleDb", "scott/tiger", 0&)

'create a dynaset object from customers

set OraDynaset = OraDatabase.CreateDynaset("select * from customers", 0&)

'retrieve a aperson column from customers. Here Value property of OraField object

'returns Person OraRef

set Person = OraDynaset.Fields("aperson").Value

'locks the Person object in the server for modifying its attributes
