For a Trusted Connection:
oConn.Open "Provider=OraOLEDB.Oracle;" & _
"Data Source=MyOracleDB;" & _
"User Id=/;" & _
"Password=;"
' Or
oConn.Open "Provider=OraOLEDB.Oracle;" & _
"Data Source=MyOracleDB;" & _
"OSAuthent=1;"
Note: "Data Source=" must be set to the appropriate Net8 name which is known to the naming method in use. For example, for Local Naming, it is the alias in the tnsnames.ora file; for Oracle Names, it is the Net8 Service Name.

OLE DB Provider for Simple Provider
The Microsoft OLE DB Simple Provider (OSP) allows ADO to access any data for which a provider has
been written using the OLE DB Simple Provider Toolkit. Simple providers are intended to access data
sources that require only fundamental OLE DB support, such as in-memory arrays or XML documents.
OSP in MDAC 2.6 has been enhanced to support opening hierarchical ADO Recordsets over arbitrary
XML files. These XML files may contain the ADO XML persistence schema, but it is not required. This
has been implemented by connecting the OSP to the MSXML2.DLL, therefore MSXML2.DLL or newer is
required.
oConn.Open "Provider=MSDAOSP;" & _
"Data Source=MSXML2.DSOControl.2.6;"
oRS.Open "http://WebServer/VirtualRoot/MyXMLFile.xml", oConn

OLE DB Provider for SQL Server
For Standard Security:
oConn.Open "Provider=sqloledb;" & _
"Data Source=myServerName;" & _
"Initial Catalog=myDatabaseName;" & _
"User Id=myUsername;" & _
"Password=myPassword;"
For a Trusted Connection:
oConn.Open "Provider=sqloledb;" & _
"Data Source=myServerName;" & _
"Initial Catalog=myDatabaseName;" & _
"Integrated Security=SSPI;"
To connect to a "Named Instance" (SQL Server 2000)
oConn.Open "Provider=sqloledb;" & _
"Data Source=myServerName\Inst2;" & _
"Initial Catalog=myDatabaseName;" & _
"User Id=myUsername;" & _
"Password=myPassword;"
To Prompt user for username and password:
oConn.Provider = "sqloledb"
oConn.Properties("Prompt") = adPromptAlways
oConn.Open "Data Source=myServerName;" & _
"Initial Catalog=myDatabaseName;"
To connect via an IP address:
oConn.Open "Provider=sqloledb;" & _
"Data Source=xxx.xxx.xxx.xxx,1433;" & _
"Network Library=DBMSSOCN;" & _
"Initial Catalog=myDatabaseName;" & _
"User ID=myUsername;" & _
"Password=myPassword;"
Note:
- xxx.xxx.xxx.xxx is an IP address
- "Network Library=DBMSSOCN" tells OLE DB to use TCP/IP rather than Named Pipes (Q238949)
- 1433 is the default port number for SQL Server
- You can also add "Encrypt=yes" for encryption

Remote Data Service (RDS) Connections
The following examples show how to connect to a remote database using the RDS Data Control.
When using the RDS DataControl's Server/SQL/Connect properties, the RDS DataControl uses the
RDS DataFactory on the remote server. If you use the RDS DataControl's URL property,
then the RDS DataFactory is not used at all.
WARNING: The RDS DataFactory can be a major security hole if not setup and configured correctly!
For more information, see RDS FAQ #24
RDS DataControl - Connect Property
With the RDS default handler disabled (not recommend due to security risks):
With oRdc
.Server = "http://carl2"
.Sql = "Select * From Authors Where State = 'CA'"
.Connect = "Provider=sqloledb;" & _
"Data Source=(local);" & _
"Initial Catalog=pubs;" & _
"User Id=sa;" & _
"Password=;"
.Refresh
End With
