Controlling the Default Bookmark Setting for Rowsets in the Single-Tier "Lite" Edition OLE DB Provider for ODBC Data Sources
The BookmarkDefault keyword in the Extended Property segment of the connect string controls whether the Provider creates rowsets with or without a bookmark column. OLE DB does not specify what the default behavior should be.
The Single-Tier "Lite" Edition OLE DB Provider for ODBC Data Sources includes a bookmark column by default.
It is not generally necessary to change this setting, but you can explicitly turn bookmarks on or off with an entry of the form:
BookmarkDefault = On BookmarkDefault = Off
