Microsoft Jet OLE DB 4.0

.NET Framework Data Provider for OLE DB

  • Use an OLE DB provider from .NET

    Provider=any oledb provider's name;OledbKey1=someValue;OledbKey2=someValue;

    See the respective OLEDB provider's connection strings options. The .net OleDbConnection will just pass on the connection string to the specified OLEDB provider. Read more here.

Microsoft Access accdb ODBC Driver

  • Standard Security

    Driver={Microsoft Access Driver (*.mdb, *.accdb)};Dbq=C:\mydatabase.accdb;
    Uid
    =Admin;Pwd=;
  • Workgroup

    Driver={Microsoft Access Driver (*.mdb, *.accdb)};Dbq=C:\mydatabase.accdb;
    SystemDB
    =C:\mydatabase.mdw;

    No changes were made to the .mdw file format for Office Access 2007. The Office Access 2007 Workgroup Manager creates .mdw files that are identical to those that are created in Access 2000 through Access 2003. The .mdw files that are created in those earlier versions can be used by databases in Office Access 2007.

  • Exclusive

    Driver={Microsoft Access Driver (*.mdb, *.accdb)};Dbq=C:\mydatabase.accdb;
    Exclusive
    =1;Uid=admin;Pwd=;
  • Enable admin statements

    To enable certain programatically admin functions such as CREATE USER, CREATE GROUP, ADD USER, GRANT, REVOKE and DEFAULTS (when making CREATE TABLE statements) use this connection string.

    Driver={Microsoft Access Driver (*.mdb, *.accdb)};Dbq=C:\mydatabase.accdb;
    Uid
    =Admin;Pwd=;ExtendedAnsiSQL=1;
  • Specifying locale identifier

    Use this one to specify the locale identifier which can help with non-US formated dates.

    Driver={Microsoft Access Driver (*.mdb, *.accdb)};Dbq=C:\mydatabase.accdb;
    Locale Identifier
    =2057;Uid=Admin;Pwd=;

    The above example uses the en-gb locale identifier (2057)

  • Standard connection

    Driver={Microsoft Access Driver (*.mdb, *.accdb)};Dbq=C:\mydatabase.mdb;
