ADO Connection String Samples

This page contains sample ADO connection strings for ODBC DSN / DSN-Less, OLE DB Providers, Remote Data Services (RDS), MS Remote, and MS DataShape.

Also included are ADO.NET connection strings for MySQL, ODBC, OLE DB, Oracle, and SQL Server .NET Data Providers.

These sample connection strings are compiled by Carl Prothman, a Microsoft ASP.NET MVP and Microsoft Certified Professional (MCP)

If you have an ADO or ADO.NET connection string that is not listed below, or you see an connection string that does not have the correct setting, please send an email to Carl Prothman.  Thanks!

ODBC DSN Connections

Using an ODBC DSN (Data Source Name) is a two step process.

1) You must first create the DSN via the "ODBC Data Source Administrator" program found in your computer's Control Panel (or Administrative Tools menu in Windows 2000). Make sure to create a SYSTEM DSN (not a USER DSN) when using ASP. You can also create the DSN via Visual Basic code.

2) Then use the following connection string - with your own DSN
name of course.

oConn.Open "DSN=mySystemDSN;" & _ "Uid=myUsername;" & _ "Pwd=myPassword" 
oConn.Open "FILEDSN=c:\somepath\mydb.dsn;" & _ "Uid=myUsername;" & _ "Pwd=myPassword"

For more information, see:  About ODBC data sources and 
How to Use File DSNs and DSN-less Connections

Note: The problem with DSN is that Users can (and will) modify or delete them by mistake, then your program won't work so well. So it's better to use a DSN-Less or OLE DB Provider connection string - with a Trusted Connection if possible!


ODBC DSN-Less Connections

For Standard Security:

oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _ "Dbq=c:\somepath\mydb.mdb;" & _ "Uid=admin;" & _ "Pwd=" 

If you are using a Workgroup (System database):

oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _ "Dbq=c:\somepath\mydb.mdb;" & _ "SystemDB=c:\somepath\mydb.mdw;", _ "myUsername", "myPassword" 

If want to open up the MDB exclusively

oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _ "Dbq=c:\somepath\mydb.mdb;" & _ "Exclusive=1;" & _ "Uid=admin;" & _ "Pwd=" 

If MDB is located on a Network Share

oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _ "Dbq=\\myServer\myShare\myPath\myDb.mdb;" & _ "Uid=admin;" & _ "Pwd=" 

If MDB is located on a remote machine

- Or use an XML Web Service via SOAP Toolkit or ASP.NET
- Or upgrade to SQL Server and use an IP connection string
- Or use an ADO URL with a remote ASP web page
- Or use a MS Remote or RDS connection string
  

If you don't know the path to the MDB (using ASP)

<% ' ASP server-side code oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _ "Dbq=" & Server.MapPath(".") & "\myDb.mdb;" & _ "Uid=admin;" & _ "Pwd=" %>

This assumes the MDB is in the same directory where the ASP page is running. Also make sure this directory has Write permissions for the user account.
 

If you don't know the path to the MDB (using VB)

oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _ "Dbq=" & App.Path & "\myDb.mdb;" & _ "Uid=admin;" & _ "Pwd="

This assumes the MDB is in the same directory where the application is running.

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

The SQLXMLOLEDB provider is an OLE DB provider that exposes the Microsoft SQLXML functionality through ADO. The SQLXMLOLEDB provider is not a rowset provider; it can only execute commands in the "write to an output stream" mode of ADO.  

oConn.Open "Provider=SQLXMLOLEDB.3.0;" & _ "Data Provider=SQLOLEDB;" & _ "Data Source=mySqlServerName;" & _ "Initial Catalog=myDatabaseName;" & _ "User Id=myUserName;" & _ "Password=myUserPassword"

For more information, see:  SQLXML 3.0 and A Survey of Microsoft SQL Server 2000 XML Features

oConn.Open "Provider=ASAProv;" & _ "Data source=myASA"

For more information, see:  ASA Programming Interfaces Guide and ASA User's Guide


oConn.Open "Provider=Sybase ASE OLE DB Provider;" & _ "Data source=myASEServer"
' Or
oConn.Open "Provider=Sybase.ASEOLEDBProvider;" & _ "Srvr=myASEServer,5000;" & _ "Catalog=myDBName;" & _ "User Id=myUserName;" & _ "Password=myUserPassword"

Where:
- The Sybase ASE OLE DB provider from the Sybase 12.5 client CD
- 5000 is the port number for Sybase.

Note: The Open Client 12 Sybase OLE DB Provider fails to work without creating  a Data Source .IDS file using the Sybase Data Administrator.  These .IDS files resemble ODBC DSNs.

Note: With Open Client 12.5, the server port number feature finally works, allowing fully qualified network connection strings to be used without defining any .IDS Data Source files.

For more information, see:  Sybase Advance Search   


Actually there is no OLE DB Provider for Text files.  However, you can use the OLE DB Provider for JET to read and write data in Text files.  Or you can use the ODBC Driver for Text.


oConn.Open "Provider=Ardent.UniOLEDB;" & _ "Data source=myServer;" & _ "Location=myDatabase;" & _ "User ID=myUsername;" & _ "Password=myPassword" 

For more information, see: Ardent Using UniOLEDB 5.1Informix Using UniOLEDB 5.2


oConn.Open "Provider=vfpoledb;" & _ "Data Source=C:\vfp7\Samples\Data\myVFPDB.dbc;" & _ "Mode=ReadWrite|Share Deny None;" & _ "Collating Sequence=MACHINE;" & _ "Password=''"

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/Connect / SQL 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 

WARNING: RDS is considered obsolete by Microsoft
 

With the RDS default handler disabled

With oRdc .Server = "http://myServerName" .Sql = "Select * From Authors Where State = 'CA'" .Connect = "Provider=sqloledb;" & _ "Data Source=(local);" & _ "Initial Catalog=pubs;" & _ "User Id=myUsername;" & _ "Password=myPassword" .Refresh End With 

With the RDS default handler enabled

With oRdc .Server = "http://myServerName" .Handler = "MSDFMAP.Handler" .Connect = "Data Source=MyConnectTag;" .Sql = "MySQLTag(""CA"")" .Refresh End With

The corresponding CONNECT and SQL sections in the default handler \WINNT\MSDFMAP.INI  file would be:

[connect MyConnectTag] Access = ReadWrite Connect = "Provider=sqloledb; Data Source=(local); Initial Catalog=pubs; User Id=sa; Password="  (put all of this on single line!) [sql MySQLTag] Sql = "Select * From Authors Where State = '?'"

For more information about the RDS Default Handler, see: Q243245, Q230680, and RDS Customization Handler Microsoft articles

To get records from a remote database

With oRdc .URL = "http://myServerName/AuthorsGet.asp?state=CA" .Refresh End With 

To save, set the URL property to an ASP web page

With oRdc .URL = "http://myServerName/AuthorsSave.asp" .SubmitChanges End With
Note: You must use MDAC 2.5 (or greater) for this feature

MS Remote Provider Connections

The following connections strings use Microsoft's remote provider  (MS Remote).  The MS Remote provider tells ADO to communicate  with the remote server (via the RDS DataFactory) and to use the  remote provider that is installed on the remote server.

WARNING:  The RDS DataFactory can be a major security hole if not setup and configured correctly!  For more information, see RDS FAQ #24 

WARNING: RDS is considered obsolete by Microsoft
 

If you want to use an ODBC DSN on the remote machine

oConn.Open "Provider=MS Remote;" & _ "Remote Server=http://myServerName;" & _ "Remote Provider=MSDASQL;" & _ "DSN=AdvWorks;" & _ "Uid=myUsername;" & _ "Pwd=myPassword" 

If you want to use an OLE DB Provider on the remote machine

oConn.Open "Provider=MS Remote;" & _ "Remote Server=http://myServerName;" & _ "Remote Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=c:\somepath\mydb.mdb", _ "admin", "" 

If you want to use an OLE DB Provider on the remote machine

oConn.Open "Provider=MS Remote;" & _ "Remote Server=http://myServerName;" & _ "Handler=MSDFMAP.Handler;" & _ "Data Source=MyAdvworksConn"

The corresponding entry in the \winnt\Msdfmap.ini file would be:

[connect MyAdvworksConn] Access = ReadWrite Connect = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=mydb.mdb; User Id=admin; Password=" (put all of this on single line!)
 

If you want to use an ODBC DSN on the remote machine

oConn.Open "Provider=MS Remote;" & _ "Remote Server=http://myServerName;" & _ "Remote Provider=MSDASQL;" & _ "DSN=myDatabaseName;" & _ "Uid=myUsername;" & _ "Pwd=myPassword" 

If you want to use an OLE DB Provider on the remote machine

oConn.Open "Provider=MS Remote;" & _ "Remote Server=http://myServerName;" & _ "Remote Provider=SQLOLEDB;" & _ "Data Source=myServerName;" & _ "Initial Catalog=myDatabaseName;" & _ "User ID=myUsername;" & _ "Password=myPassword" 

If you want to use an OLE DB Provider on the remote machine

oConn.Open "Provider=MS Remote;" & _ "Remote Server=http://myServerName;" & _ "Handler=MSDFMAP.Handler;" & _ "Data Source=MyPubsConn" 

The corresponding entry in the \winnt\Msdfmap.ini file would be:

[connect MyPubsConn] Access = ReadWrite Connect = "Provider=SQLOLEDB; Data Source=myServerName; Initial Catalog=myDatabaseName; User ID=myUsername; Password=myPassword" (put all of this on single line!)

ADO URL Connections

ADO 2.5+ allows you to open up a Recordset based on XML returned from an ASP file over HTTP.  This feature doesn't use RDS at all.

To get records from a remote database

oRs.Open "http://myServer/AuthorsGetByState.asp?state=CA",, _ adOpenStatic, adLockBatchOptimistic

To save changes

' Save Recordset into Stream Set oStm = New ADODB.Stream oRs.Save oStm, adPersistXML ' Use MSXML's XMLHTTP object to open ASP Set oXMLHTTP = New MSXML2.XMLHTTP30 oXMLHTTP.Open "POST", "http://myServerName/AuthorsSave.asp" oXMLHTTP.Send oStm.ReadText ' If an error occurred If oXMLHTTP.Status = 500 Then Debug.Print oXMLHTTP.statusText End If

For more information, see:  ADO Recordset's Open Method




.NET Data Provider Connections

The SQL Server .NET Data Provide allows you to connect to a Microsoft SQL Server 7.0 or 2000 databases.  

For Microsoft SQL Server 6.5 or earlier, use the OLE DB .NET Data Provider with  the "SQL Server OLE DB Provider" (SQLOLEDB).

Note: The SQL Server .NET Data Provider knows which Provider it is.  Hence the "provider=" part of the connection string is not needed.

Using C#:

using System.Data.SqlClient; ... SqlConnection oSQLConn = new SqlConnection(); oSQLConn.ConnectionString = "Data Source=(local);" + "Initial Catalog=mySQLServerDBName;" + "Integrated Security=yes"; oSQLConn.Open(); 

Using VB.NET:

Imports System.Data.SqlClient ... Dim oSQLConn As SqlConnection = New SqlConnection() oSQLConn.ConnectionString = "Data Source=(local);" & _ "Initial Catalog=mySQLServerDBName;" & _ "Integrated Security=yes" oSQLConn.Open() 

If connection to a remote server (via IP address):

oSQLConn.ConnectionString = "Network Library=DBMSSOCN;" & _ "Data Source=xxx.xxx.xxx.xxx,1433;" & _ "Initial Catalog=mySQLServerDBName;" & _ "User ID=myUsername;" & _ "Password=myPassword"

Where:
- "Network Library=DBMSSOCN" tells SqlConnection to use TCP/IP Q238949
- xxx.xxx.xxx.xxx is an IP address.  
- 1433 is the default port number for SQL Server.  Q269882 and Q287932
- You can also add "Encrypt=yes" for encryption 
 

For more information, see:  System.Data.SQL Namespace, Q308656, and .NET Data Providers

Note: Microsoft SQLXML Managed Classes exposes the functionality of SQLXML inside the Microsoft .NET Framework.

The OLE DB .NET Data Provider uses native OLE DB through COM interop to enable data access.  

To use the OLE DB .NET Data Provider, you must also use an OLE DB provider (e.g.  SQLOLEDB, MSDAORA, or Microsoft.JET.OLEDB.4.0).

For IBM AS/400 OLE DB Provider

' VB.NET Dim oOleDbConnection As OleDb.OleDbConnection Dim sConnString As String = _ "Provider=IBMDA400.DataSource.1;" & _ "Data source=myAS400DbName;" & _ "User Id=myUsername;" & _ "Password=myPassword" oOleDbConnection = New OleDb.OleDbConnection(sConnString) oOleDbConnection.Open() 

For JET OLE DB Provider

' VB.NET Dim oOleDbConnection As OleDb.OleDbConnection Dim sConnString As String = _ "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=C:\myPath\myJet.mdb;" & _ "User ID=Admin;" & _ "Password="  oOleDbConnection = New OleDb.OleDbConnection(sConnString) oOleDbConnection.Open() 

For Oracle OLE DB Provider

' VB.NET Dim oOleDbConnection As OleDb.OleDbConnection Dim sConnString As String = _ "Provider=OraOLEDB.Oracle;" & _ "Data Source=MyOracleDB;" & _ "User ID=myUsername;" & _ "Password=myPassword"  oOleDbConnection = New OleDb.OleDbConnection(sConnString) oOleDbConnection.Open()

The ODBC .NET Data Provider is an add-on component to the .NET Framework SDK. It provides access to native ODBC drivers the same way the OLE DB .NET Data Provider provides access to native OLE DB providers.

For SQL Server ODBC Driver

' VB.NET Dim oODBCConnection As Odbc.OdbcConnection Dim sConnString As String = _ "Driver={SQL Server};" & _ "Server=MySQLServerName;" & _ "Database=MyDatabaseName;" & _ "Uid=MyUsername;" & _ "Pwd=MyPassword" oODBCConnection = New Odbc.OdbcConnection(sConnString) oODBCConnection.Open() 

For Oracle ODBC Driver

' VB.NET Dim oODBCConnection As Odbc.OdbcConnection Dim sConnString As String = _ "Driver={Microsoft ODBC for Oracle};" & _ "Server=OracleServer.world;" & _ "Uid=myUsername;" & _ "Pwd=myPassword" oODBCConnection = New Odbc.OdbcConnection(sConnString) oODBCConnection.Open() 

For Access (JET) ODBC Driver

' VB.NET Dim oODBCConnection As Odbc.OdbcConnection Dim sConnString As String = _ "Driver={Microsoft Access Driver (*.mdb)};" & _ "Dbq=c:\somepath\mydb.mdb;" & _ "Uid=Admin;" & _ "Pwd=" oODBCConnection = New Odbc.OdbcConnection(sConnString) oODBCConnection.Open() 

For Sybase System 11 ODBC Driver

// C# string myConnStr = "Driver={Sybase System 11};" + "SRVR=mySybaseServerName;" + "DB=myDatabaseName;" + "UID=myUsername;" + "PWD=myPassword"; OdbcConnection myConnection = new OdbcConnection(myConnStr); myConnection.Open(); 

For all other ODBC Drivers

' VB.NET Dim oODBCConnection As Odbc.OdbcConnection Dim sConnString As String = "Dsn=myDsn;" & _                       "Uid=myUsername;" & _ "Pwd=myPassword" oODBCConnection = New Odbc.OdbcConnection(sConnString) oODBCConnection.Open()

The .NET Framework Data Provider for Oracle is an add-on component to the .NET Framework that provides access to an Oracle database using the Oracle Call Interface (OCI) as provided by Oracle Client software.  

Using C#:

using System.Data.OracleClient; OracleConnection oOracleConn = new OracleConnection(); oOracleConn.ConnectionString = "Data Source=Oracle8i;" + "Integrated Security=yes"; oOracleConn.Open(); 

Using VB.NET:

Imports System.Data.OracleClient  Dim oOracleConn As OracleConnection = New OracleConnection() oOracleConn.ConnectionString = "Data Source=Oracle8i;" & _ "Integrated Security=yes"; oOracleConn.Open()

Note: You must have the Oracle 8i Release 3 (8.1.7) Client or later installed in order for this provider to work correctly.

Note: You must have the RTM version of the .NET Framework installed in order for this provider to work correctly.

Note: There are known Oracle 7.3, Oracle 8.0, and Oracle9i client and server problems in this beta release. The server-side issues should be resolved in the final release of the product.  However, Oracle 7.3 client will not be supported.
